Book excerpt: Classical novae are thermonuclear runaways at the envelope of a WD due to the piling up of H-rich accreted material. They have been observed to produce heavy elements during the explosion, and their role in galactical abundances for some specific elements may not be negligible. MESA (Modules for Experiments in Stellar Astrophysics) code has been thoroughly studied for its application to nova explosions. Detailed know-how of nova simulations with MESA has been achieved, leading the road of future studies using this tool. Its capablities in the field have been tested, demonstrating to reach further than what has been done in previous literature. MESA has been shown to give accurate nucleosynthesis yields for solar-like accreted material without any further postprocessing up to 50 nova bursts. The dependance of the nova outburst properties with the burst number have been anayzed. However, more simulations are needed in order to extract meaningful conclusions about the role of the burst number in the properties of novae outbursts. The key role of the nuclear reaction network has been highlighted, showing that simulations of consecutive novae outbursts require nuclear reactions networks specifically tested for the work. Many nuclear reaction networks that were thoroughly tested in a single nova explosion have not been capable of properly simulating 10 consecutive outbursts. The role of convective overshoot mixing as implemented in MESA has also been tested. It has been found that as shown in previous literature, it does account for dredge up. We plan to extend this work with simulations of consecutive nova outbursts implementing convective overshoot.

Download or read book Astrophysics written by Judith Ann Irwin and published by John Wiley & Sons. This book was released on 2023-08-01 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: ASTROPHYSICS This is a balanced textbook presenting the theory and observations of stars and their evolution—a cornerstone of Astrophysics. Astrophysics: Decoding the Stars is a companion volume to Astrophysics: Decoding the Cosmos from astrophysics teacher and researcher, Professor Judith Irwin. The text presents an accessible, student-friendly guide to the key theories and principles of stars, emphasizing the close connection between observation and theory. To aid in reader comprehension, the text includes online resources and problems at the end of each chapter. Many highlighted boxes summarize key concepts or point to example stars that can be seen with the naked eye. The text focuses on physical concepts, but it also refers to the results of numerical models using online resources. Sample topics covered in Astrophysics: Decoding the Stars include: The Sun, gaseous and radiative processes Stellar interiors, energy transport mechanisms, stellar cores and nuclear energy generation, the global energy budget, timescales, and stability Observational constraints, variable stars, and star formation from molecular clouds to the ZAMS Evolutionary tracks on the HR diagram for stars of different masses, and how stars end their lives Stellar remnants — white dwarfs, neutron stars and pulsars, and black holes Astrophysics: Decoding the Stars is a highly useful textbook resource for second- to fourth-year undergraduate students pursuing an Astrophysics program, along with Physics undergraduates who have opted to take stellar structure and evolution as part of their program. It will also be useful for new graduate students who want a solid grounding in stellar astrophysics.

Download or read book A Study of White Dwarfs written by Spencer Caldwell and published by . This book was released on 2019 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Novae, be it classical, dwarf, or supernovae, are some of the most powerful and luminous events observed in the Universe. Although they share the same root, they are produced by different physical processes. We research systems capable of experiencing novae with the intention of furthering our understanding of these astrophysical phenomena. A cataclysmic variable is a binary star system that contains a white dwarf with the potential of undergoing classical or dwarf novae. A recent observation of a white dwarf within one of these systems was found to have an unusually high surface temperature for its orbital period. The discovery contradicts current evolutionary models, motivating research to determine a theoretical justification for this outlier. Using MESA (Modules for Experiments in Stellar Astrophysics), we simulated novae for a progenitor designed to represent a white dwarf in an interacting binary. We developed post-novae cooling timescales to constrain the temperature value. We found the rate at which classical novae cool post-outburst (

This book was released on 2011-11-24 with total page 747 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique book brings together a comprehensive set of papers on the background, theory, technical issues and applications of agent-based modelling (ABM) within geographical systems. This collection of papers is an invaluable reference point for the experienced agent-based modeller as well those new to the area. Specific geographical issues such as handling scale and space are dealt with as well as practical advice from leading experts about designing and creating ABMs, handling complexity, visualising and validating model outputs. With contributions from many of the world’s leading research institutions, the latest applied research (micro and macro applications) from around the globe exemplify what can be achieved in geographical context. This book is relevant to researchers, postgraduate and advanced undergraduate students, and professionals in the areas of quantitative geography, spatial analysis, spatial modelling, social simulation modelling and geographical information sciences.

This book was released on 2017-12-21 with total page 684 pages. Available in PDF, EPUB and Kindle. Book excerpt: Southwest Asia is one of the most remarkable regions on Earth in terms of active faulting and folding, large-magnitude earthquakes, volcanic landscapes, petroliferous foreland basins, historical civilizations as well as geologic outcrops that display the protracted and complex 540 m.y. stratigraphic record of Earth's Phanerozoic Era. Emerged from the birth and demise of the Paleo-Tethys and Neo-Tethys oceans, southwest Asia is currently the locus of ongoing tectonic collision between the Eurasia-Arabia continental plates. The region is characterized by the high plateaus of Iran and Anatolia fringed by the lofty ranges of Zagros, Alborz, Caucasus, Taurus, and Pontic mountains; the region also includes the strategic marine domains of the Persian Gulf, Gulf of Oman, Caspian, and Mediterranean. This 19-chapter volume, published in honor of Manuel Berberian, a preeminent geologist from the region, brings together a wealth of new data, analyses, and frontier research on the geologic evolution, collisional tectonics, active deformation, and historical and modern seismicity of key areas in southwest Asia.
