MELCHIORS: The Mercator Library of High Resolution Stellar Spectroscopy
P. Royer, T. Merle, K. Dsilva +71
Over the past decades, libraries of stellar spectra have been used in a large variety of science cases, including as sources of reference spectra for a given object or a given spec…
Asteroseismic modelling of the two F-type hybrid pulsators KIC10080943A and KIC10080943B
V. S. Schmid, C. Aerts
Pulsating binary stars are ideal targets for testing the theory of stellar structure and evolution. Fundamental parameters can be derived to high precision from binary modelling an…
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…
KIC 10080943: a binary star with two Doradus/ Scuti hybrid pulsators. Analysis of the g modes
M. A. Keen, T. R. Bedding, S. J. Murphy +5
We use four years of Kepler photometry to study the non-eclipsing spectroscopic binary KIC 10080943. We find both components to be Doradus/ Scuti hybrids, which pulsate in b…
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…
Detection of solar-like oscillations in the bright red giant stars Psc and Tau from a 190-day high-precision spectroscopic multisite campaign
P. G. Beck, E. Kambe, M. Hillen +35
Red giants are evolved stars which exhibit solar-like oscillations. Although a multitude of stars have been observed with space telescopes, only a handful of red-giant stars were t…
Discovery of binarity, spectroscopic frequency analysis, and mode identification of the delta Sct star 4CVn
V. S. Schmid, N. Themeßl, M. Breger +12
More than 40 years of ground-based photometric observations of the delta Sct star 4CVn revealed 18 independent oscillation frequencies, including radial as well as non-radial p-mod…
Understanding the dynamical structure of pulsating stars. HARPS spectroscopy of the delta Scuti stars rho Pup and DX Cet
N. Nardetto, E. Poretti, M. Rainer +4
High-resolution spectroscopy is a powerful tool to study the dynamical structure of pulsating stars atmosphere. We aim at comparing the line asymmetry and velocity of the two delta…
Pulsating red giant stars in eccentric binary systems discovered from Kepler space-based photometry
P. G. Beck, K. Hambleton, J. Vos +30
The unparalleled photometric data obtained by NASA's Kepler space telescope led to an improved understanding of red giant stars and binary stars. Seismology allows us to constrain…
A search for pulsations in the HgMn star HD 45975 with CoRoT photometry and ground-based spectroscopy
T. Morel, M. Briquet, M. Auvergne +28
The existence of pulsations in HgMn stars is still being debated. To provide the first unambiguous observational detection of pulsations in this class of chemically peculiar object…
Low-amplitude rotational modulation rather than pulsations in the CoRoT B-type supergiant HD 46769
C. Aerts, S. Simon-Diaz, C. Catala +16
{We aim to detect and interpret photometric and spectroscopic variability of the bright CoRoT B-type supergiant target HD\,46769 (). We also attempt to detect a magnetic fi…
The GAPS Programme with HARPS-N@TNG II: No giant planets around the metal-poor star HIP 11952
S. Desidera, A. Sozzetti, A. S. Bonomo +37
In the context of the program Global Architecture of Planetary Systems (GAPS), we have performed radial velocity monitoring of the metal-poor star HIP 11952 on 35 nights over about…
