Spectroscopic survey of Kepler stars. II. FIES/NOT observations of A- and F-type stars
E. Niemczura, M. Polińska, S. J. Murphy +7
We have analysed high-resolution spectra of 28 A and 22 F stars in the Kepler field, observed with the FIES spectrograph at the Nordic Optical Telescope. We provide spectral types,…
Photometric and spectroscopic variability of the B5IIIe star HD 171219
L. Andrade, E. Janot-Pacheco, M. Emilio +11
We analyzed the star HD 171219, one of the relatively bright Be stars observed in the seismo field of the CoRoT satellite, in order to determine its physical and pulsation characte…
Spectroscopic Survey of γ Doradus Stars I. Comprehensive atmospheric parameters and abundance analysis of γ Doradus stars
F. Kahraman-Alicavus, E. Niemczura, P. De Cat +11
We present a spectroscopic survey of known and candidate \,Doradus stars. The high-resolution, high signal-to-noise spectra of 52 objects were collected by five different spectr…
Quasiperiodic patterns in Scuti stars: an in-depth study of the CoRoT star HD 174966
A. García Hernández, A. Moya, J. C. Suárez +9
In this work, we have gone one step further from the study presented in the first CoRoT symposium. Our analysis consists on constructing a model database covering the entire uncert…
KIC 4768731: a bright long-period roAp star in the Kepler Field
B. Smalley, E. Niemczura, S. J. Murphy +11
We report the identification of 61.45 d^-1 (711.2 mu Hz) oscillations, with amplitudes of 62.6-mu mag, in KIC 4768731 (HD 225914) using Kepler photometry. This relatively bright (V…
Spectroscopic survey of Kepler stars. I. HERMES/Mercator observations of A- and F-type stars
E. Niemczura, S. J. Murphy, B. Smalley +21
The Kepler space mission provided near-continuous and high-precision photometry of about 207,000 stars, which can be used for asteroseismology. However, for successful seismic mode…
