The life cycles of Be viscous decretion discs: fundamental disc parameters of 54 SMC Be stars [PDF]
, 2018 Be stars are main-sequence massive stars with emission features in their spectrum, which originates in circumstellar gaseous discs. Even though the viscous decretion disc (VDD) model can satisfactorily explain most observations, two important physical ...

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

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 ...

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 ...

Fundamental parameters of bright Ap stars from wide-range energy distributions and advanced atmospheric models [PDF]
, 2012 Aims. As a well-established procedure for the vast majority of normal main-sequence stars, determination of atmospheric and stellar parameters turns to be a challenging process in case of magnetic chemically peculiar stars.
