Detection of Solar-Like Oscillations, Observational Constraints, and Stellar Models for Cyg, the Brightest Star Observed by the {\it Kepler} Mission
J. A. Guzik, G. Houdek, W. J. Chaplin +52
Cygni is an F3 spectral-type main-sequence star with visual magnitude V=4.48. This star was the brightest star observed by the original Kepler spacecraft mission. Short-cadence…
A peculiar Of star in the Local Group galaxy IC 1613
A. Herrero, M. Garcia, J. Puls +4
Context. Results from the theory of radiatively driven winds are incorporated in stellar evolutionary and population synthesis models, and used in our interpretation of the observa…
Are the Stellar Winds in IC1613 stronger than expected?
A. Herrero, M. Garcia, K. Uytterhoeven +8
In this poster we present the results of our analyses of three early massive stars in IC 1613, whose spectra have been observed with VIMOS and analyzed with CMFGEN and FASTWIND. On…
Is macroturbulence in OB Sgs related to pulsations?
S. Simón-Díaz, A. Herrero, K. Uytterhoeven +3
As part of a long term observational project, we are investigating the macroturbulent broadening in O and B supergiants (Sgs) and its possible connection with spectroscopic variabi…
Observational evidence for a correlation between macroturbulent broadening and line-profile variations in OB Supergiants
S. Simón-Díaz, A. Herrero, K. Uytterhoeven +3
The spectra of O and B supergiants are known to be affected by a significant form of extra line broadening (usually referred to as macroturbulence) in addition to that produced by…
The nature of V39: an LBV candidate or LBV impostor in the very low metallicity galaxy IC 1613?
A. Herrero, M. Garcia, K. Uytterhoeven +4
[abridged] Context: Very few examples of luminous blue variable (LBV) stars or LBV candidates (LBVc) are known, particularly at metallicities below the SMC. The LBV phase is crucia…
Multiperiodicity in the large-amplitude rapidly-rotating Ceph ei star HD 203664
C. Aerts, P. De Cat, J. De Ridder +4
We perform a seismic study of the young massive Cephei star HD 203664 with the goal to constrain its interior structure. Our study is based on a time series of 328 new Geneva 7-…
