On TP-AGB stars and the mass of galaxies [PDF]

, 2007
Recent calculations of evolutionary tracks of TP-AGB stars of different mass and metallicity by Marigo et al. (2007) have been incorporated in the Bruzual & Charlot evolutionary population synthesis models.

The Y^2 Stellar Evolutionary Tracks [PDF]

, 2002
We present a database of the latest stellar models of the $Y^2$ (Yonsei-Yale) collaboration. This database contains the stellar evolutionary tracks from the pre-main-sequence birthline to the helium core flash that were used to construct the $Y^2 ...

Benchmarking pre-main sequence stellar evolutionary tracks using disk-based dynamical stellar masses

Astronomy & Astrophysics
Stellar 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.

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

, 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 input physics, together with the inclusion of the pre-main sequence phase, not present in our previous ...

CALIBRATION OF STELLAR PARAMETERS OF 85 PEG SYSTEM [PDF]

Journal of Astronomy and Space Sciences, 2007
We have investigated the evolutionary status of 85 Peg within the framework of standard evolutionary theory. 85 Peg has been known to be a visual and spectroscopic binary system in the solar neighborhood. In spite of the accurate information of the total

On the self-consistent physical parameters of LMC intermediate-age clusters

, 2008
The LMC clusters are unique templates of simple stellar population (SSP), being crucial to calibrate models describing the integral light as well as to test the stellar evolution theory.

MESA Isochrones and Stellar Tracks (MIST). II. Models with α-enhanced Chemical Composition

The Astrophysical Journal Supplement Series
We update and expand the MESA Isochrones and Stellar Tracks (MIST) database to include variations in the α -capture elements, specifically [ α /Fe] = −0.2, 0, +0.2, +0.4, and +0.6 for the full range of −3 ≤ [Fe/H] ≤ +0.5 already covered by MIST ...
