The discovery of a planetary candidate around the evolved low-mass Kepler giant star HD 175370
M. Hrudková, A. Hatzes, R. Karjalainen +20
We report on the discovery of a planetary companion candidate with a minimum mass Msini = 4.6 M_J orbiting the K2 III giant star HD 175370 (KIC 007940959). This star was a target i…
Modelling the asymmetric wind of the luminous blue variable binary MWC 314
A. Lobel, J. H. Groh, C. Martayan +12
We present a spectroscopic analysis of MWC 314, a luminous blue variable (LBV) candidate with an extended bipolar nebula. The detailed spectroscopic variability is investigated to…
Time resolved spectroscopy of BD+46 442: gas streams and jet creation in a newly discovered evolved binary with a disk
N. Gorlova, H. Van Winckel, C. Gielen +9
Previous studies have shown that many post-AGB stars with dusty disks are associated with single-lined binary stars. To verify the binarity hypothesis on a larger sample, we starte…
Mass ratio from Doppler beaming and Rømer delay versus ellipsoidal modulation in the Kepler data of KOI-74
S. Bloemen, T. R. Marsh, P. Degroote +18
We present a light curve analysis and radial velocity study of KOI-74, an eclipsing A star + white dwarf binary with a 5.2 day orbit. Aside from new spectroscopy covering the orbit…
Chemically tagging the Hyades stream: Does it partly originate from the Hyades cluster?
L. Pompéia, T. Masseron, B. Famaey +19
The Hyades stream has long been thought to be a dispersed vestige of the Hyades cluster. However, recent analyses of the parallax distribution, of the mass function, and of the act…
HERMES: a high-resolution fibre-fed spectrograph for the Mercator telescope
Gert Raskin, Hans Van Winckel, Herman Hensberge +18
The HERMES high-resolution spectrograph project aims at exploiting the specific potential of small but flexible telescopes in observational astrophysics. The optimised optical desi…
