Bayesian sampling with BeAtlas, a grid of synthetic Be star spectra I. Recovering the fundamental parameters of α Eri and β CMi

Monthly notices of the Royal Astronomical Society, 2023
Classical Be stars are fast rotating, near main sequence B-type stars. The rotation and the presence of circumstellar discs profoundly modify the observables of active Be stars.

Fundamental parameters for 222 B-type stars for the X-shooter Spectral Library

Proceedings of the International Astronomical Union, 2022
We use the MIDE3700 code to find effective temperatures (Teff) and surface gravities (log g) via the Barbier Chalonge Divan (BCD) method for 222 B-type stars in the ESO archive in preparation for their inclusion as an extension to the X-shooter Spectral ...

The Fundamental Parameters of Massive Stars

AIP Conference Proceedings, 2009
We analyzed far‐UV (FUSE), UV (HST, IUE) and optical spectra of hot massive stars in the Milky Way with non‐LTE, line‐blanketed models with sphericity and expanding winds. We were able to reconcile previously discrepant diagnostics from Hα to highly ionized transitions (e.g.

Asteroseismic Determination of sdB Stars Fundamental Parameters

Astrophysics and Space Science, 2004
Recent observational efforts and theoretical breakthroughs have encouraged the development of detailed asteroseismic analyses of rapidly oscillating sdB stars (the so-called EC14026 stars). This led to the first seismic determinations of the fundamental parameters that define the structure of EHB stars.

Fundamental Parameters for a Sample of Field Blue Horizontal-branch Stars

Research Notes of the AAS
With the aim of identifying hot field blue horizontal-branch (BHB) stars, spectroscopic observations of 21 candidates were carried out at the Observatoire du Mont-Mégantic.
