TL;DR: In this article, the authors present a first general characterization of the pulsational behavior of A-F type stars as observed in the Kepler light curves of a sample of 750 candidate A-f type stars, and observationally investigate the relation between γ Doradus (γ Dor), δ Scuti (δ Sct), and hybrid stars.
Journal ArticleDOI
Deviations from a uniform period spacing of gravity modes in a massive star
Pieter Degroote,Conny Aerts,Conny Aerts,A. Baglin,Andrea Miglio,Maryline Briquet,Arlette Noels,Ewa Niemczura,Josefina Montalbán,Steven Bloemen,R. Oreiro,M. Vučković,K. Smolders,M. Auvergne,Frédéric Baudin,Claude Catala,Eric Michel +16 more
TL;DR: The detection of numerous gravity modes in a young star with a mass of about seven solar masses is reported, and the mean period spacing allows the extent of the convective core to be estimated and the clear periodic deviation from the mean constrains the location of the chemical transition zone to be at about 10 per cent of the radius.
Journal ArticleDOI
Signatures of internal rotation discovered in the Kepler data of five slowly pulsating B stars
Péter Pápics,Andrew Tkachenko,T. Van Reeth,Conny Aerts,Conny Aerts,Ehsan Moravveji,M. Van de Sande,K. De Smedt,Steven Bloemen,Steven Bloemen,John Southworth,J. Debosscher,Ewa Niemczura,J. F. Gameiro +13 more
TL;DR: In this paper, the authors used spectral synthesis and disentangling techniques to derive fundamental parameters and to determine precise orbital parameters from high-resolution spectra of slowly pulsating B (SPB) stars.
Journal ArticleDOI
Gravito-inertial and pressure modes detected in the B3 IV CoRoT target HD 43317
Péter Pápics,Maryline Briquet,A. Baglin,Ennio Poretti,Conny Aerts,Pieter Degroote,Andrew Tkachenko,Thierry Morel,W. Zima,Ewa Niemczura,Monica Rainer,M. Hareter,Frédéric Baudin,C. Catala,E. Michel,R. Samadi,M. Auvergne +16 more
TL;DR: In this paper, the authors analyzed and interpreted the pulsational behavior of the B3-IV star HD43317 using the CoRoT light curve along with the ground-based spectroscopy gathered by the HARPS instrument.
