Photospheric properties and fundamental parameters of M dwarfs [PDF]
Astronomy & Astrophysics, 2018 Context. M dwarfs are an important source of information when studying and probing the lower end of the Hertzsprung-Russell (HR) diagram, down to the hydrogen-burning limit. Being the most numerous and oldest stars in the galaxy, they carry fundamental information on its chemical history.

The fundamental parameters of the roAp star 10 Aquilae [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 of these pulsators.

Accurate Fundamental Stellar Parameters [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractWe combine results from interferometry, asteroseismology and spectroscopic analyses to determine accurate fundamental parameters (mass, radius and effective temperature) of 10 bright solar-type stars covering the H-R diagram from spectral type F5 to K1. Using “direct” techniques that are only weakly model-dependent we determine the mass, radius

FUNDAMENTAL PARAMETERS AND CHEMICAL COMPOSITION OF ARCTURUS [PDF]
The Astrophysical Journal, 2011 We derive a self-consistent set of atmospheric parameters and abundances of 17 elements for the red giant star Arcturus: Teff = 4286+/-30 K, logg = 1.66+/-0.05, and [Fe/H] = -0.52+/-0.04. The effective temperature was determined using model atmosphere fits to the observed spectral energy distribution from the blue to the mid-infrared (0.44 to 10 um ...

Fundamental Parameters of Cepheids: Masses and Multiplicity [PDF]
AIP Conference Proceedings, 2009 Masses determined from classical Cepheids in binary systems are a primary test of both pulsation and evolutionary calculations. The first step is to determine the orbit from ground-based radial velocities. Complementary satellite data from Hubble, FUSE, IUE, and Chandra provide full information about the system. A summary of recent results on masses is

Inversion of stellar fundamental parameters from Espadons and Narval high-resolution spectra [PDF]
, 2014 The general context of this study is the inversion of stellar fundamental parameters from high-resolution Echelle spectra. We aim indeed at developing a fast and reliable tool for the post-processing of spectra produced by Espadons and Narval ...

The fundamental parameters of the roAp starγ Equulei [PDF]
Astronomy & Astrophysics, 2011 Physical processes working in the stellar interiors as well as the evolution of stars depend on some fundamental stellar properties, such as mass, radius, luminosity, and chemical abundances. A classical way to test stellar interior models is to compare the predicted and observed location of a star on theoretical evolutionary tracks in a H-R diagram ...
