Fundamental parameters of eight Am stars: comparing observations with theory★ [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 In this paper we present a detailed analysis of a sample of eight Am stars, four of them are in the Kepler field of view. We derive fundamental parameters for all observed stars, effective temperature, gravity, rotational and radial velocities, and chemical abundances by spectral synthesis method.

The fundamental parameters of the roAp star 10 Aql [PDF]
Astronomy & Astrophysics, 2013 Due to the strong magnetic field and related abnormal surface layers existing in rapidly oscillating Ap stars, systematic errors are likely to be present when determining their effective temperatures, which potentially compromises asteroseismic studies ...

FUNDAMENTAL PARAMETERS OF MAIN-SEQUENCE STARS IN AN INSTANT WITH MACHINE LEARNING [PDF]
The Astrophysical Journal, 2016 ABSTRACT Owing to the remarkable photometric precision of space observatories like Kepler, stellar and planetary systems beyond our own are now being characterized en masse for the first time. These characterizations are pivotal for endeavors such as searching for Earth-like planets and solar twins, understanding the mechanisms that ...

Fundamental parameters and evolutionary status of the magnetic chemically peculiar stars HD 188041 (V1291 Aquilae), HD 111133 (EP Virginis), and HD 204411: spectroscopy versus interferometry [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 The determination of fundamental parameters of stars is one of the main tasks of astrophysics. For magnetic chemically peculiar stars, this problem is complicated by the anomalous chemical composition of their atmospheres, which requires special ...

Fundamental Parameters of Be Stars Seen Equator-On [PDF]
International Astronomical Union Colloquium, 2002 AbstractThe geometric deformation, as well as the non-uniform surface gravity and temperature distributions induced by the fast rotation, are taken into account to determine the fundamental parameters of 10 Be stars seen nearly equator-on. The stars occur in the first half of the main sequence evolutionary span, which suggests that their fast rotation ...

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 of the Ap-stars GO And, 84 UMa, and K 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 funda-
