Kepler observations of A-F pre-main sequence stars in Upper Scorpius: Discovery of six new ~Scuti and one ~Doradus stars
V. Ripepi, L. Balona, G. Catanzaro +3
We present light curves and periodograms for 27 stars in the young Upper Scorpius association (age=\,Myr) obtained with the Kepler spacecraft. This association is only th…
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…
Pulsation frequency distribution in Delta Scuti stars
L. A. Balona, J. Daszynska-Daszkiewicz, A. A. Pamyatnykh
We study the frequency distributions of Delta Scuti stars observed by the Kepler satellite in short-cadence mode. To minimize errors in the estimated stellar parameters, we divided…
Analysis of Kepler B stars: rotational modulation and Maia variables
L. A. Balona, A. S. Baran, J. Daszynska-Daszkiewicz +1
We examine 4-yr almost continuous Kepler photometry of 115 B stars. We find that the light curves of 39 percent of these stars are simply described by a low-frequency sinusoid and…
Oscillations in stellar superflares
L. A. Balona, A. -M. Broomhall, A. Kosovichev +3
Two different mechanisms may act to induce quasi-periodic pulsations (QPP) in whole-disk observations of stellar flares. One mechanism may be magneto-hydromagnetic (MHD) forces and…
Spots on Am stars
L. A. Balona, G. Catanzaro, O. P. Abedigamba +2
We investigate the light variations of 15 Am stars using four years of high-precision photometry from the Kepler spacecraft and an additional 14 Am stars from the K2 Campaign 0 fie…
