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…
Photometric study of two beta Cephei pulsators in eclipsing systems
D. Drobek, A. Pigulski, R. R. Shobbrook +1
We present results of a photometric study of the young southern open cluster Stock 14. This cluster is known to contain two eclipsing systems with presumed beta Cephei components,…
Atmospheric Parameters of 169 F, G, K and M-type Stars in the Kepler Field
J. Molenda-Zakowicz, S. G. Sousa, A. Frasca +15
The asteroseismic and planetary studies, like all research related to stars, need precise and accurate stellar atmospheric parameters as input. We aim at deriving the effective tem…
Variability Survey in the Open Cluster Stock 14 and the Surrounding Fields
D. Drobek, A. Pigulski, R. R. Shobbrook +1
We present the results of a photometric variability survey in the young open cluster Stock 14 and the surrounding fields. In total, we detected 103 variable stars of which 88 are n…
Spectroscopic and Photometric Observations of Kepler Asteroseismic Targets
J. Molenda-Zakowicz, M. Jerzykiewicz, G. Kopacki +10
We summarize our ground-based program of spectroscopic and photometric observations of the asteroseismic targets of the Kepler space telescope. We have already determined atmospher…
New pulsating variable stars in the Stock 14 open cluster and surrounding fields
D. Drobek
This paper presents the preliminary results of a multicolour photometric study of the young open cluster Stock 14 and adjacent fields. The reddening, distance and age of the cluste…
Variable Stars in the Open Cluster NGC 7044
G. Kopacki, D. Drobek, Z. Kolaczkowski +1
We present results of a search for variable stars in the intermediate-age open cluster NGC 7044. We found 23 variable stars in the observed field. One star turned out to be of the…
Spectroscopic and photometric study of two B-type pulsators in eclipsing systems
D. Drobek, A. Pigulski
Pulsating stars in eclipsing binary systems play an important role in asteroseismology. The combination of their spectroscopic and photometric orbital solutions can be used to dete…
