Progress on nuclear reaction rates affecting the stellar production of 26Al

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2022
The radioisotope 26Al is a key observable for nucleosynthesis in the Galaxy and the environment of the early Solar System. To properly interpret the large variety of astronomical and meteoritic data, it is crucial to understand both the nuclear ...

Is there a mass discrepancy in the Cepheid binary OGLE-LMC-CEP0227? [PDF]

open access: yes, 2011
Context. The Cepheid mass discrepancy, the difference between masses predicted from stellar evolution and stellar pulsation calculations, is a challenge for the understanding of stellar astrophysics. Recent models of the eclipsing binary Cepheid OGLE-LMC-

Stellar Evolution Models of Young Stars: Progress and Limitations

open access: yes, 2015
Stellar evolution models are a cornerstone of young star astrophysics, which necessitates that they yield accurate and reliable predictions of stellar properties.

Code dependencies of pre-supernova evolution and nucleosynthesis in massive stars: Evolution to the end of core helium burning [PDF]

open access: yes, 2014
Massive stars are key sources of radiative, kinetic and chemical feedback in the Universe. Grids of massive star models computed by different groups each using their own codes, input physics choices and numerical approximations, however, lead to ...

On compressive radial tidal forces

open access: yes, 2007
Radial tidal forces can be compressive instead of disruptive, a possibility that is frequently overlooked in high level physics courses. For example, radial tidal compression can emerge in extended stellar systems containing a smaller stellar cluster ...

parsec: stellar tracks and isochrones with the PAdova and TRieste Stellar Evolution Code [PDF]

open access: yes, 2012
We present the updated version of the code used to compute stellar evolutionary tracks in Padova. It is the result of a thorough revision of the major in put physics, together with the inclusion of the pre‐main sequence phase, not present in our previous

Uncertainties in AGB Evolution and Nucleosynthesis

open access: yes, 2016
We summarise the evolution and nucleosynthesis in AGB and Super-AGB stars. We then examine the major sources of uncertainty, especially mass-loss.Comment: 8 pages, no figures.

Observationally-Motivated Analysis of Simulated Galaxies [PDF]

open access: yes, 2014
The spatial and temporal relationships between stellar age, kinematics, and chemistry are a fundamental tool for uncovering the physics driving galaxy formation and evolution.
