Eclipsing binaries in the MACHO database: New periods and classifications for 3031 systems in the Large Magellanic Cloud [PDF]
, 2007 Eclipsing binaries offer a unique opportunity to determine fundamental physical parameters of stars using the constraints on the geometry of the systems. Here we present a reanalysis of publicly available two-color observations of about 6800 stars in the

Precise determination of fundamental parameters of six exoplanet host stars and their planets [PDF]
, 2014 The aim of this paper is to determinate the fundamental parameters of six exoplanet host (EH) stars and their planets. Because techniques for detecting exo-planets yield properties of the planet only as a function of the properties of the host star, we ...

The fundamental parameters of the Ap star 78 Virginis [PDF]
Astronomy & Astrophysics, 2015 Context. Determining the effective temperature of Ap stars, including the roAp stellar pulsators, is a difficult task owing to their strong magnetic field and their related spotted surfaces. It is, however, an important step towards constraining models of their complex atmosphere and testing proposed pulsation excitation mechanisms. Aims.

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 ...

Fundamental Parameters : Normal A0 Dwarf Stars of the Solar Neighbourhood [PDF]
Highlights of Astronomy, 1998 The purpose of this paper is to define a set of “standard”, “reference” or “comparison” stars, according to their use, of spectral type A0V in order to be used for further studies in the domain of peculiar stars as well as normal stars of thisTeffand luminosity range.
