Fundamental Parameters of He-Weak and He-Strong Stars [PDF]

Astronomy & Astrophysics, 2007
We carried out low resolution spectroscopic observations in the wavelength range 3400-4700 A of 20 He-weak and 8 He-strong stars to determine their fundamental parameters by means of the Divan-Chalonge-Barbier (BCD) spectrophotometric system.

Fundamental Parameters of Massive Stars [PDF]

EAS Publications Series, 2003
We discuss the determination of fundamental parameters of `normal' hot, massive OB-type stars, namely temperatures, luminosities, masses, gravities and surface abundances.

Using limb darkening to measure fundamental parameters of stars [PDF]

Astronomy & Astrophysics, 2012
Context. Limb darkening is an important tool for understanding stellar atmospheres, but most observations measuring limb darkening assume various parameterizations that yield no significant information about the structure of stellar atmospheres. Aims. We

Fundamental stellar parameters of benchmark stars from CHARA interferometry [PDF]

Astronomy & Astrophysics, 2022
Context. Stellar models applied to large stellar surveys of the Milky Way need to be properly tested against a sample of stars with highly reliable fundamental stellar parameters. We have established a programme aiming to deliver such a sample of stars. Aims.

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 ...

Fundamental parameters and infrared excesses of Hipparcos stars [PDF]

Royal Astronomical Society. Monthly Notices, 2012
We derive the fundamental parameters (temperature and luminosity) of 107 619 Hipparcos stars and place these stars on a true Hertzsprung-Russell diagram.

Atmospheric and Fundamental Parameters of Eight Nearby Multiple Stars

The Astronomical Journal, 2022
Abstract We present the complete set of atmospheric and fundamental parameters, in addition to the masses, for the individual components of eight stellar systems. The list of the systems, whose orbital solutions were published recently, includes seven binaries (HIP 14524, HIP 16025, HIP 46199, HIP 47791, HIP 60444, HIP 61100, HIP 73085 ...

Fundamental parameters of RR Lyrae stars from multicolour photometry and Kurucz atmospheric models -- III. SW And, DH Peg, CU Com, DY Peg [PDF]

, 2014
We report the most comprehensive UBV(RI)_C observations of the bright, radially pulsating field stars SW And, DH Peg, CU Com, DY Peg. Long term variation has been found in the ultraviolet colour curves of SW And and DH Peg.

Fundamental parameters of Be stars located in the seismology fields of COROT [PDF]

, 2005
In preparation for the COROT space mission, we determined the fundamental parameters (spectral type, temperature, gravity, vsini) of the Be stars observable by COROT in its seismology fields (64 Be stars).

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.
