Pulsations in the late-type Be star HD 50209 detected by CoRoT (2009)
Diago, P. D., Gutierrez-Soto, J., Auvergne, M., Fabregat, J., Floquet, M., ...
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 mass-loss...
Silvester, J., Neiner, C., Henrichs, H. F., Wade, G. A., Petit, V., Alecian, E., ...
We have obtained 40 high-resolution circular spectropolarimetric measurements of 12 slowly-pulsating B (SPB) stars, 8 Beta Cephei stars and two Be stars with the ESPaDOnS and NARVAL...
Fundamental parameters of B Supergiants from the BCD System (2009)
Zorec, J., Cidale, L., Arias, M. L., Fremat, Y., Muratore, M. F., Torres, A. F., ...
Effective temperatures of early-type supergiants are important to test stellar atmosphere- and internal structure-models of massive and intermediate mass objects at different evolutionary phases....
More on pulsating B-type stars in the Magellanic Clouds (2009)
Diago, P. D., Gutiérrez-Soto, J., Fabregat, J., Martayan, C.
We present here the results of our research for B-type pulsators in low metallicity environments, searching for short-term periodic variability in a large sample of B and Be stars in the Magellanic...
The Gaia satellite: a tool for Emission Line Stars and Hot Stars (2008)
Martayan, C, Frémat, Y, Blomme, R, Jonckheere, A, Borges, M, De Batz, B, ...
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 provide parallaxes for...
Pulsating B and Be stars in the Magellanic Clouds (2008)
Diago, P. D., Gutiérrez-Soto, J., Fabregat, J., Martayan, C., Suso, J.
Stellar pulsations in main-sequence B-type stars are driven by the $\kappa$-mechanism due to the Fe-group opacity bump. The current models do not predict the presence of instability strips in the B...
Pulsating B and Be stars in the Magellanic Clouds (2008)
Diago, P. D., Gutiérrez-Soto, J., Fabregat, J., Martayan, C., Suso, J.

Pulsating B and Be stars in the Small Magellanic Cloud (2007)
Diago, P. D., Gutierrez-Soto, J., Fabregat, J., Martayan, C.
Context: Stellar pulsations in main-sequence B-type stars are driven by the kappa-mechanism due to the Fe-group opacity bump. The current models do not predict the presence of instability strips in...
Rotation in the ZAMS: Be and Bn stars (2006)
Zorec, J., Frémat, Y., Martayan, C., Cidale, L., Torres, A.
We show that Be stars belong to a high velocity tail of a single B-type star rotational velocity distribution in the MS. This implies that: 1) the number fraction N(Be)/N(Be+B) is independent of the...
