Download or read book The Globular Star Clusters of the Andromeda Galaxy written by Charli M Sakari and published by Morgan & Claypool Publishers. This book was released on 2019-12-30 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a brief compilation of results from nearly a century of research on the globular star clusters in the Andromeda Galaxy (M31). It explores the techniques and limitations of the observations, the successes and challenges of the models, and the paradigm for the formation of M31 that has gradually emerged. These results will eventually be superseded by new data, better analysis techniques, and more complex models. However, the emphasis of this book is on the techniques, thought processes, and connections with other studies.
Download or read book Messier s Nebulae and Star Clusters written by Kenneth Glyn Jones and published by Cambridge University Press. This book was released on 1991-04-04 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Charles Messier's catalog of nebulae and star clusters, published in 1784, marked the start of a new era of deep-sky astronomy. Today, this tradition of observing galaxies and clusters is kept alive by dedicated amateur astronomers. Nearly all the objects are visible in a small telescope, and many, such as the Crab Nebula and the Andromeda galaxy, are among the most fascinating objects in the universe. Kenneth Glyn Jones has revised his definitive version of Messier's catalog. His own observations and drawings, together with maps and diagrams, make this a valuable introduction to deep-sky observing. Historical and astrophysical notes bring the science of these nebulae right up to date. This is a unique handbook, unlikely ever to be equaled in its completeness and importance to the telescope owner.

Download or read book Nebulae Star Clusters Galaxies written by Wolfgang Steinicke and published by BoD – Books on Demand. This book was released on 2019-05-23 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nebulae, star clusters, and galaxies are outside our solar system. They belong to the 'deep sky' and lead the observer to great distances and at the same time the view goes far into the past. The light of the most distant galaxies took billions of years to reach us. No less fascinating is our home galaxy, the Milky Way, offering many bright nebulae and star clusters. The book covers three important topics related to deep-sky objects: history, astrophysics, and observation. When beginners observe an object visually, not knowing anything about it, they will only perceive a faint spot of light - nothing really exciting. So, to get the right 'cosmic' feeling, the view should be enriched with stories about the object's discovery, distance, physical nature, or evolution. Supplied with this kind of information, deep-sky observing becomes a fascinating activity - braving the cold and darkness. Over time, advanced fields such as observation techniques or astrophotography come into play. The book informs the reader about all these topics and offers a comprehensive collection of interesting targets.

Download or read book Globular Clusters Guides to Galaxies written by Tom Richtler and published by Springer Science & Business Media. This book was released on 2008-11-23 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principal question of whether and how globular clusters can contribute to a better understanding of galaxy formation and evolution is perhaps the main driving force behind the overall endeavour of studying globular cluster systems. Naturally, this splits up into many individual problems. The objective of the Joint ESO-FONDAP Workshop on Globular Clusters - Guides to Galaxies was to bring together researchers, both observational and theoretical, to present and discuss the most recent results. Topics covered in these proceedings are: internal dynamics of globular clusters and interaction with host galaxies (tidal tails, evolution of cluster masses), accretion of globular clusters, detailed descriptions of nearby cluster systems, ultracompact dwarfs, formations of massive clusters in mergers and elsewhere, the ACS Virgo survey, galaxy formation and globular clusters, dynamics and kinematics of globular cluster systems and dark matter-related problems. With its wide coverage of the topic, this book constitutes a valuable reference of the scientific knowledge of the field.

Download or read book Star Cluster Formation Efficiency in the Andromeda Galaxy written by Lent Clifton Johnson IV and published by . This book was released on 2015 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work revolutionizes the study of star clusters in the Local Group galaxy Andromeda (Messier 31) using high spatial resolution, multi-wavelength imaging from the Hubble Space Telescope obtained as part of the Panchromatic Hubble Andromeda Treasury (PHAT) survey. I construct a cluster catalog using visual identification methods, including the use of image classifications collected from citizen scientist volunteers as part of the Andromeda Project. I perform analysis that combines large numbers of volunteer classifications with expert-derived identifications to yield a well-characterized census of star clusters. The resulting cluster catalog surpasses existing Galactic and extragalactic samples in terms of completeness and uniformity, serves as the basis for a wide range of current and future investigations of star formation and stellar evolution in M31, and is an important legacy data product of the PHAT survey. I use the PHAT star cluster catalog and associated cluster age and mass characterizations to study two aspects of star cluster formation. First, I investigate cluster formation efficiency and its dependence on star formation intensity. This study combines detailed measurements of cluster ages and masses with star formation histories of underlying total stellar populations, where both sets of constraints are derived from fitting color-magnitude diagrams of individually resolved stars. I find that ~4% of young stars (10-100 Myr old) in M31 are born in long-lived star clusters, and demonstrate that this fraction varies systematically as a function of star formation rate surface density ([unknown math symbol]SFR) and gas depletion time ([unknown math symbol]dep). The results derived here agree with trends established by previous observations of nearby galaxies in which cluster formation efficiency correlates with star formation rate intensity. The spatially-resolved measurements of cluster formation efficiency in M31 are also consistent with theoretical predictions, providing observational support for a model of cluster formation in which star clusters are born in regions of high gas density and star formation efficiency within a hierarchically-structured interstellar medium. In addition to star cluster formation efficiency, I also study the mass distribution of the young cluster populations (10-300 Myr old) in M31. I find that the mass function shape is well described by a Schechter function, with a power law index of [unknown math symbol] = -1.99 +̲ 0.12 and a characteristic mass of Mc = 8.5+2.8-1.8 M[unknown math symbol]. This exponential high-mass truncation of the cluster mass function occurs at a significantly lower mass in M31 than found for other nearby star forming galaxies. I show for the first time that the exponential truncation of the cluster mass function varies systematically with star formation rate intensity, such that the characteristic Schechter mass increases with star formation rate surface density as Mc [unknown math symbol] [unknown math symbol]SFR^~1.3. Additionally, I explore the possibility that the Mc-[unknown math symbol]SFR relation derived here might also apply to old globular cluster systems, and thus be useful in constraining properties of star formation environments in the early universe.
Download or read book The Complex Lives of Star Clusters written by David Stevenson and published by Springer. This book was released on 2015-05-09 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: As with the author’s recent books Extreme Explosions and Under a Crimson Sun, the complex topic of star clusters is broken down and made accessible with clear links to other areas of astronomy in a language which the non-specialist can easily read and enjoy. The full range of topics are addressed regarding how star clusters are formed. Why is it some are dense conglomerates of stars while others are looser associations? Are the young, brilliant clusters seen in neighboring galaxies such as the Large Magellanic Cloud, M33 or M82 analogous to the ancient globulars seen in the Milky Way? How will these clusters change as their stars wane and die? More interestingly, how does living in a dense star cluster affect the fates of the stars and any attendant planets that accompany them? Star clusters form many of the most dazzling objects in the astronomers’ catalogs. Many amateur astronomers are interested in exploring how these objects are created and what it would be like to live among these objects. From the historical views of how star clusters came about to the most recent assumptions about how stars within these clusters evolve, different strands of science, from observation to theory, are woven together into a compelling investigation specifically targeted at amateur astronomers.
