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…
Gravity-mode period spacings as seismic diagnostic for a sample of gamma Doradus stars from Kepler space photometry and high-resolution ground-based spectroscopy
T. Van Reeth, A. Tkachenko, C. Aerts +20
Gamma Doradus stars (hereafter gamma Dor stars) are gravity-mode pulsators of spectral type A or F. Such modes probe the deep stellar interior, offering a detailed fingerprint of t…
Ground-Based Transit Observations of the Super-Earth 55 Cnc e
E. J. W. de Mooij, M. Lopez-Morales, R. Karjalainen +2
We report the first ground-based detections of the shallow transit of the super-Earth exoplanet 55 Cnc e using a 2-meter-class telescope. Using differential spectrophotometry, we o…
Detecting non-uniform period spacings in the Kepler photometry of gamma Doradus stars: methodology and case studies
T. Van Reeth, A. Tkachenko, C. Aerts +9
Context. The analysis of stellar oscillations is one of the most reliable ways to probe stellar interiors. Recent space missions such as Kepler have provided us with an opportunity…
Detection of a large sample of Gamma Dor stars from Kepler space photometry and high-resolution ground-based spectroscopy
A. Tkachenko, C. Aerts, A. Yakushechkin +10
The space-missions MOST, CoRoT, and Kepler deliver a huge amount of high-quality photometric data suitable to study numerous pulsating stars. Our ultimate goal is a detection and a…
Detection of gravity modes in the massive binary V380 Cyg from Kepler spacebased photometry and high-resolution spectroscopy
A. Tkachenko, C. Aerts, K. Pavlovski +17
We report the discovery of low-amplitude gravity-mode oscillations in the massive binary star V380 Cyg, from 180 d of Kepler custom-aperture space photometry and 5 months of high-r…
HD 181068: A Red Giant in a Triply-Eclipsing Compact Hierarchical Triple System
A. Derekas, L. L. Kiss, T. Borkovits +41
Hierarchical triple systems comprise a close binary and a more distant component. They are important for testing theories of star formation and of stellar evolution in the presence…
Two Type Ic supernovae in low-metallicity, dwarf galaxies: diversity of explosions
D. R. Young, S. J. Smartt, S. Valenti +15
We present BVRI photometry and optical spectroscopy of two Type Ic supernovae SN 2007bg and SN 2007bi discovered in wide-field, non-targeted surveys and associated with sub-luminou…
WASP-3b: a strongly-irradiated transiting gas-giant planet
D. Pollacco, I. Skillen, A. Collier Cameron +43
We report the discovery of WASP-3b, the third transiting exoplanet to be discovered by the WASP and SOPHIE collaboration. WASP-3b transits its host star USNO-B1.0 1256-0285133 ever…
