The excitation of pulsation modes in β Cephei and Slowly Pulsating B stars is known to be very sensitive to opacity changes in the stellar interior where T ∼ 2 × 10 5 K. In this region differences in opacity up to ∼ 50% can be induced by the choice between OPAL and OP opacity tables, and between two different metal mixtures (Grevesse & Noels 1993 and Asplund et al. 2005). We have extended the non-adiabatic computations presented in Miglio et al. (2007) towards models of higher mass and…

Testing the effects of opacity and the chemical mixture on the excitation of pulsations in B stars
• Physics
• 2012
The B-type pulsators known asβ Cephei and Slowly Pulsating B (SPB) stars present pulsations driven by theκ mechanism, which operates thanks to an opacity bump due to the iron group elements. In
Pulsating B and Be stars in the Small Magellanic Cloud
• Physics
• 2008
Context. Stellar pulsations in main-sequence B-type stars are driven by the κ -mechanism due to the Fe-group opacity bump. The current models do not predict the presence of instability strips in the
SPB stars in the open SMC cluster NGC 371
• Physics
• 2008
Pulsation in β Cep and slowly pulsating B (SPB) stars are driven by the K mechanism which depends critically on the metallicity. It has therefore been suggested that β Cep and SPB stars should be
Main-sequence instability strip for different opacities and heavy element abundances: a comparison with observations
• Physics
• 2008
Updated theoretical instability domains are presented for ? Cephei and SPB star models. Calculations were performed using new OP opacities for old (GN93) and new (A04) solar heavy element mixtures.
Domains of pulsational instability of low-frequency modes in rotating upper main sequence stars
• Physics
• 2017
We determine instability domains on the Hertzsprung-Russel diagram for rotating main sequence stars with masses 2-20 $\mathrm M_\odot$. The effects of the Coriolis force are treated in the framework
Kepler observations of the variability in B-type stars
• Physics
• 2011
The analysis of the light curves of 48 B-type stars observed by Kepler is presented. Among these are 15 pulsating stars, all of which show low frequencies, characteristic of slowly pulsating B (SPB)
The IACOB project. IV. New predictions for high-degree non-radial mode instability domains in massive stars and their connection with macroturbulent broadening
• Physics
• 2017
Context. Asteroseismology is a powerful tool to access the internal structure of stars. Apart from the important impact of theoretical developments, progress in this field has been commonly
Spectral and photometric study of Be Stars in the first exoplanet fields of CoRoT
• Physics, Geology
Proceedings of the International Astronomical Union
• 2010
Abstract First we investigate the spectral and photometric properties (colours, magnitudes) of a sample of faint Be stars observed in the first exoplanet fields of CoRoT (IR1, LRA1 and LRC1). We
Is macroturbulent broadening in OB Supergiants related to pulsations
• Physics
• 2010
The spectrum of O and B Supergiants is known to be affected by an important extra line-broadening (usually called macroturbulence) that adds to stellar rotation. Recent analysis of high resolution
Outbursts and stellar properties of the classical Be star HD 6226
• Physics, Geology
Monthly Notices of the Royal Astronomical Society
• 2021
The bright and understudied classical Be star HD 6226 has exhibited multiple outbursts in the last several years during which the star grew a viscous decretion disc. We analyse 659 optical spectra
