Characterizing six seismic solar analogs observed by Kepler, K2, and HERMES
R. A. GarcÃa, S. Mathur, G. T. Hookway +31
Solar analogs, stars that closely match the fundamental properties of the Sun, provide key benchmarks for testing stellar structure and evolution across different ages and activity…
Self-Consistent Nonlinear Classical Cepheid Pulsations During Stellar Evolution with MESA
Ebraheem Farag, Earl P. Bellinger, Philip Mocz +5
We extend the time-dependent convection treatment in \code{MESA} by introducing eddy-viscous damping. This software change brings \code{MESA-TDC} into closer alignment with the rad…
Red-Giant Asteroseismology of Low-Mass Population III Stars
Thiago Ferreira, Earl P. Bellinger, Ebraheem Farag +1
Low-mass stars from the first epoch of star formation may still persist in the Milky Way and its satellite dwarf galaxies today; however, their detection is confounded by surface p…
The Effect of Different Methods for Accounting for -enhancement on the Asteroseismic Modeling of Metal-Poor Stars
Christopher J. Lindsay, J. M. Joel Ong, Sarbani Basu +2
Constraining stellar models using asteroseismic and spectroscopic observations is a powerful method for precisely determining the fundamental properties of stars in different kinem…
Evolution of Low-Mass Population III Stars: Convection, Mass Loss, Nucleosynthesis, and Neutrinos
Thiago Ferreira, Earl P. Bellinger, Ebraheem Farag +1
The first stars likely formed from pristine clouds, marking a transformative epoch after the dark ages by initiating reionisation and synthesising the first heavy elements. Among t…
Precise Asteroseismic Ages for the Helmi Streams
Christopher J. Lindsay, Marc Hon, J. M. Joel Ong +6
The Helmi streams are remnants of a dwarf galaxy that was accreted by the Milky Way and whose stars now form a distinct kinematic and chemical substructure in the Galactic halo. Pr…
