Kepler Eclipsing Binary Stars. VII. The Catalog of Eclipsing Binaries Found in the Entire Kepler Data-Set
Brian Kirk, Kyle Conroy, Andrej Prša +47
The primary Kepler Mission provided nearly continuous monitoring of ~200,000 objects with unprecedented photometric precision. We present the final catalog of eclipsing binary syst…
Internal rotation of the red-giant star KIC 4448777 by means of asteroseismic inversion
M . P. Di Mauro, R. Ventura, D. Cardini +13
In this paper we study the dynamics of the stellar interior of the early red-giant star KIC 4448777 by asteroseismic inversion of 14 splittings of the dipole mixed modes obtained f…
Tiling strategies for optical follow-up of gravitational wave triggers by wide field of view telescopes
Shaon Ghosh, Steven Bloemen, Gijs Nelemans +2
Binary neutron stars are among the most promising candidates for joint gravitational-wave and electromagnetic astronomy. The goal of this work is to investigate the strategy of usi…
Looking at the bright side - The story of AA Dor as revealed by its cool companion
Maja Vučković, Roy H. Østensen, Peter Németh +2
Irradiation effects in close binaries are crucial for a reliable determination of system parameters and understanding the close binary evolution. We study irradiated light originat…
BEER analysis of Kepler and CoRoT light curves: IV. Discovery of four new low-mass white dwarf companions in the Kepler data
Simchon Faigler, Ilya Kull, Tsevi Mazeh +3
We report the discovery of four short-period eclipsing systems in the Kepler light curves, consisting of an A-star primary and a low-mass white dwarf (WD) secondary (dA+WD) - KIC 4…
KIC 10080943: An eccentric binary system containing two pressure- and gravity-mode hybrid pulsators
V. S. Schmid, A. Tkachenko, C. Aerts +14
Gamma Doradus and delta Scuti pulsators cover the transition region between low mass and massive main-sequence stars, and as such, are critical for testing stellar models. When the…
Phase resolved spectroscopy and Kepler photometry of the ultracompact AM CVn binary SDSS J190817.07+394036.4
T. Kupfer, P. J. Groot, S. Bloemen +8
{\it Kepler} satellite photometry and phase-resolved spectroscopy of the ultracompact AM CVn type binary SDSS J190817.07+394036.4 are presented. The average spectra reveal a variet…
Kepler's first view of O-star variability: K2 data of five O stars in Campaign 0 as a proof-of-concept for O-star asteroseismology
B. Buysschaert, C. Aerts, S. Bloemen +9
We present high-precision photometric light curves of five O-type stars observed with the refurbished {\it Kepler\/} satellite during its Campaign 0. For one of the stars, we also…
SDSS J1152+0248: An eclipsing double white dwarf from the Kepler K2 campaign
N. Hallakoun, D. Maoz, M. Kilic +13
We report the discovery of the sixth known eclipsing double white dwarf (WD) system, SDSS J1152+0248, with a 2.3968 +/- 0.0003 h orbital period, in data from the Kepler Mission's K…
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…
