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

Astronomy & Astrophysics, 2020
Context.Benchmark stars are crucial as validating standards for current as well as future large stellar surveys of the Milky Way. However, the number of suitable metal-poor benchmark stars is currently limited, owing to the difficulty in determining reliable effective temperatures (Teff) in this regime.Aims.We aim to construct a new set of metal-poor ...

B stars in open clusters: fundamental parameters [PDF]

Proceedings of the International Astronomical Union, 2010
AbstractWe use the BCD spectrophotometric classification system to derive fundamental parameters of B stars in NGC 2439, NGC 3766 and NGC 6087. We are able to perform a complete study of each open cluster by deriving spectral classification of its members, distance modulus and age as well.

Fundamental parameters of “normal” B stars in the solar neighborhood [PDF]

Proceedings of the International Astronomical Union, 2010
AbstractUnderstanding phenomena of activity in stars, like pulsations or magnetism, benefits from systematic comparisons of some key physical parameters of active with those of “normal” stars. Here we concentrate on a careful derivation of fundamental parameters of a well selected sample of 27 “normal” B stars in nearby OB associations and in the field.

Fundamental parameters and infrared excesses of Hipparcos stars

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. This is achieved by comparing BT-Settl model atmospheres to spectral energy distributions (SEDs) created from Hipparcos, Tycho, SDSS, DENIS, 2MASS, MSX, AKARI, IRAS and WISE data. We also identify and

Fundamental parameters of the Ap-stars GO And, 84 UMa, and κ Psc [PDF]

Astronomy & Astrophysics, 2021
Aims. The aim of this work is to determine fundamental parameters of three Ap stars, GO And (HD 4778), κ Psc (HD 220825), and 84 UMa (HD 120198), using spectroscopic techniques. By analysing these stars, we complete the sample of Ap stars for which fundamental parameters have additionally been derived by means of interferometry.

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 ...

The Fundamental Stellar Parameters of FGK Stars in the SEEDS Survey

, 2017
Large exoplanet surveys have successfully detected thousands of exoplanets to-date. Utilizing these detections and non-detections to constrain our understanding of the formation and evolution of planetary systems also requires a detailed understanding of the basic properties of their host stars.

The fundamental parameters of the roAp star α Circini [PDF]

Monthly Notices of the Royal Astronomical Society, 2008
Abstract We have used the Sydney University Stellar Interferometer to measure the angular diameter of α Cir. This is the first detailed interferometric study of a rapidly oscillating A (roAp) star, α Cir being the brightest member of its class.
