The magnetic field of the double-lined spectroscopic binary system HD 5550
E. Alecian, A. Tkachenko, C. Neiner +3
(Abridged) In the framework of the BinaMicS project, we have begun a study of the magnetic properties of a sample of intermediate-mass and massive short-period binary systems, as a…
Weak magnetic field, solid-envelope rotation, and wave-induced N-enrichment in the SPB star Cassiopeiae
M. Briquet, C. Neiner, P. Petit +3
Aims. The main-sequence B-type star Cassiopeiae is known as a N-rich star with a magnetic field discovered with the Musicos spectropolarimeter. We model the magnetic field of t…
The MiMeS Survey of Magnetism in Massive Stars: Introduction and overview
G. A. Wade, C. Neiner, E. Alecian +47
The MiMeS project is a large-scale, high resolution, sensitive spectropolarimetric investigation of the magnetic properties of O and early B type stars. Initiated in 2008 and compl…
Search for magnetic fields in particle-accelerating colliding-wind binaries
C. Neiner, J. Grunhut, B. Leroy +2
Some colliding-wind massive binaries, called particle-accelerating colliding-wind binaries (PACWB), exhibit synchrotron radio emission, which is assumed to be generated by a stella…
gamma Peg: testing Vega-like magnetic fields in B stars
C. Neiner, D. Monin, B. Leroy +2
gam Peg is a bright B pulsator showing both p and g modes of beta Cep and SPB types. It has also been claimed to be a magnetic star by some authors while others do not detect a mag…
Discovery of a magnetic field in the CoRoT hybrid B-type pulsator HD 43317
M. Briquet, C. Neiner, B. Leroy +2
A promising way of testing the impact of a magnetic field on internal mixing (core overshooting, internal rotation) in main-sequence B-type stars is to perform asteroseismic studie…
The Kepler characterization of the variability among A- and F-type stars. I. General overview
K. Uytterhoeven, A. Moya, A. Grigahcene +38
The Kepler spacecraft is providing time series of photometric data with micromagnitude precision for hundreds of A-F type stars. We present a first general characterization of the…
Kepler observations of variability in B-type stars
L. A. Balona, A. Pigulski, P. De Cat +27
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 SPB sta…
Photometric variability of the Be star CoRoT-ID 102761769
M. Emilio, L. Andrade, E. Janot-Pacheco +16
Classical Be stars are rapid rotators of spectral type late O to early A and luminosity class V-III, wich exhibit Balmer emission lines and often a near infrared excess originating…
Asteroseismology of Solar-type Stars with Kepler I: Data Analysis
C. Karoff, W. J. Chaplin, T. Appourchaux +46
We report on the first asteroseismic analysis of solar-type stars observed by Kepler. Observations of three G-type stars, made at one-minute cadence during the first 33.5d of scien…
The asteroseismic potential of Kepler: first results for solar-type stars
W. J. Chaplin, T. Appourchaux, Y. Elsworth +105
We present preliminary asteroseismic results from Kepler on three G-type stars. The observations, made at one-minute cadence during the first 33.5d of science operations, reveal hi…
Pulsations in the late-type Be star HD 50209 detected by CoRoT
P. D. Diago, J. Gutierrez-Soto, M. Auvergne +22
The presence of pulsations in late-type Be stars is still a matter of controversy. It constitutes an important issue to establish the relationship between non-radial pulsations and…
The Gaia satellite: a tool for Emission Line Stars and Hot Stars
Christophe Martayan, Yves Fremat, Ronny Blomme +19
The Gaia satellite will be launched at the end of 2011. It will observe at least 1 billion stars, and among them several million emission line stars and hot stars. Gaia will provid…
