Dynamical Stellar Masses of Pre-main-sequence Stars in Lupus and Taurus Obtained with ALMA Surveys in Comparison with Stellar Evolutionary Models [PDF]
The Astrophysical Journal, 2021 Abstract We analyzed archival molecular line data of pre-main-sequence (PMS) stars in the Lupus and Taurus star-forming regions obtained with ALMA surveys with an integration time of a few minutes per source. We stacked the data of 13CO and C18O (J = 2–1 and 3–2) and CN (N = 3–2, J = 7/2–5/2) lines to enhance the signal-to-noise ratios ...

Probing high-mass stellar evolutionary models with binary stars [PDF]
Proceedings of the International Astronomical Union, 2014 AbstractMass discrepancy is one of the problems that is pending a solution in (massive) binary star research field. The problem is often solved by introducing an additional near core mixing into evolutionary models, which brings theoretical masses of individual stellar components into an agreement with the dynamical ones.

Applications of the k–ω Model in Stellar Evolutionary Models [PDF]
The Astrophysical Journal, 2017 Abstract The k–ω model for turbulence was first proposed by Kolmogorov. A new k–ω model for stellar convection was developed by Li, which could reasonably describe turbulent convection not only in the convectively unstable zone, but also in the overshooting regions.

Benchmarking pre-main sequence stellar evolutionary tracks using disk-based dynamical stellar masses
Astronomy & AstrophysicsStellar masses are a fundamental property to understand models of pre-main sequence evolution, but their values derived from Hertzsprung–Russell (HR) diagrams are strongly model dependent.

Stellar evolutionary models from the zero-age main sequence to the first thermal pulse
The Astrophysical Journal Supplement Series, 1991 Detailed numerical tabulations of 32 stellar evolutionary sequences extending from either the zero-age main sequence (ZAMS) or the zero-age horizontal branch (ZAHB), and through to the occurrence of thermal pulses on the asymptotic giant branch, are presented. The models span a range of 1-3 M ○. (except for one 4 M ○. and one 5 M ○. model) and cover
