We present a new database of stellar evolution models for a large range of masses and chemical compositions, based on an up-to-date theoretical framework. We briefly discuss the physical inputs and the assumptions adopted in computing the stellar.
24 Μαΐ 2023 · Our knowledge of stellar evolution is driven by one-dimensional (1D) simulations. 1D models, however, are severely limited by uncertainties on the exact behaviour of many multidimensional...
We start in Sect. 2 with a brief summary of the equations of stellar structure and evolution, and an overview of the main evolutionary properties of models of different initial masses, to set the stage for the discussion that follows.
28 Ιουν 2024 · We explore a simulation-based inference (SBI) workflow to infer from optical absorption spectra the posterior distributions of metallicities and the star formation histories (SFHs) of galaxies (i.e. the star formation rate as a function of time).
plications in computational stellar astrophysics. A 1-D stellar evolution module, MESA star, combines many of the numerical and physics modules for simulations of a wide range of stellar evolution scenarios ranging from very-low mass to mas-sive stars, including advanced evolutionary phases. MESA star solves the fully
An Introduction to the Theory of Stellar Structure and Evolution. Second Edition. Using fundamental physics, the theory of stellar structure and evolution can predict how stars are born, how their complex internal structure changes, what nuclear fuel they burn, and their ultimate fate.
Although the details of the theory of stellar evolution are complex, it is possible to gain some insight into the results expected of these calculations from some simple considerations.
