A volume-limited survey of mCP stars within 100 pc – I. Fundamental parameters and chemical abundances [PDF]

Monthly notices of the Royal Astronomical Society, 2018
We present the first results of a volume-limited survey of main sequence (MS) magnetic chemically peculiar (mCP) stars. The sample consists of all identified intermediate-mass MS stars (mCP and non-mCP) within a heliocentric distance of $100\,{\rm pc ...

Benchmarking the fundamental parameters of Ap stars with optical long-baseline interferometric measurements

Astronomy & Astrophysics, 2020
Context. The variety of physical processes at play in chemically peculiar stars makes it difficult to determine their fundamental parameters. In particular, for the magnetic ones, called Ap stars, the strong magnetic fields and the induced spotted ...

Fundamental parameters of B type stars [PDF]

Proceedings of the International Astronomical Union, 2014
AbstractFundamental parameters of 26 well-studied sharp-lined single early B-type stars in OB associations and in the field within a distance of ≤400 pc from the Sun are compared to high-precision data from detached eclipsing binaries (DEBs). Fundamental parameters are derived from accurate and precise atmospheric parameters determined earlier by us ...

The IGRINS YSO Survey. I. Stellar Parameters of Pre-main-sequence Stars in Taurus-Auriga [PDF]

Astrophysical Journal, 2021
We present fundamental parameters for 110 canonical K- and M-type (1.3−0.13 M ⊙) Taurus-Auriga young stellar objects (YSOs). The analysis produces a simultaneous determination of effective temperature (T eff), surface gravity (log g), magnetic-field ...

Accurate fundamental parameters of eclipsing binary stars [PDF]

Proceedings of the International Astronomical Union, 2004
The study of detached eclipsing binaries is one of the most powerful ways to investigate the properties of individual stars and stellar systems. We present preliminary masses, radii and effective temperatures for the eclipsing binary WW Aurigae, which is composed of two metallic-lined A-type stars.

The Gaia–Kepler Stellar Properties Catalog. I. Homogeneous Fundamental Properties for 186,301 Kepler Stars [PDF]

Astronomical Journal, 2020
An accurate and precise Kepler Stellar Properties Catalog is essential for the interpretation of the Kepler exoplanet survey results. Previous Kepler Stellar Properties Catalogs have focused on reporting the best-available parameters for each star, but ...
