Influence of the initial orbital period and accretion efficiency on the low-mass binary evolution [PDF]
Serbian Astronomical Journal, 2021 This paper presents detailed evolutionary models of low-mass binary systems (1.25 + 1 M⊙) with initial orbital periods of 10, 50 and 100 days and accretion efficiency of 10%, 20%, 50%, and a conservative assumption.

Influence of surface stressing on stellar coronae and winds [PDF]
, 2013 STFC funding has supported this research.The large-scale field of the Sun is well represented by its lowest energy (or potential) state. Recent observations, by comparison, reveal that many solar-type stars show large-scale surface magnetic fields that ...

Young Populous Clusters in the Magellanic Clouds – Implications for Stellar Evolutionary Models [PDF]
Symposium - International Astronomical Union, 1999 We present new UV, visual and Hα photometry obtained with the WFPC2 of NGC 330, NGC 1818, NGC 2004 and NGC 2100, four young populous clusters in the MCs. We present observational evidence for a degree of convective core overshoot in excess of that currently applied in standard models.

The Astronomical Journal, 2022 Abstract Population III stars were the first stars to form after the Big Bang and are believed to have made the earliest contribution to the metal content of the universe beyond the products of the Big Bang nucleosynthesis. These stars are theorized to have had extremely short life spans and therefore would only be observable at high ...

Stellar masses of SDSS-III BOSS galaxies at z~0.5 and constraints to galaxy formation models [PDF]
, 2013 We calculate stellar masses for ∼400 000 massive luminous galaxies at redshift ∼0.2–0.7 using the first two years of data from the Baryon Oscillation Spectroscopic Survey (BOSS).

YONSEI EVOLUTIONARY POPULATION SYNTHESIS (YEPS) MODEL. I. SPECTROSCOPIC EVOLUTION OF SIMPLE STELLAR POPULATIONS [PDF]
The Astrophysical Journal Supplement Series, 2012 We present a series of papers on the year-2012 version of Yonsei Evolutionary Population Synthesis (YEPS) model which is constructed on over 20 years of heritage. This first paper delineates the spectroscopic aspect of integrated light from stellar populations older than 1 Gyr.
