The young binary HD 102077: Orbit, spectral type, kinematics, and moving group membership
Maria Wöllert, Wolfgang Brandner, Sabine Reffert +4
The K-type binary star HD 102077 was proposed as a candidate member of the TW Hydrae Association (TWA) which is a young (5-15 Myr) moving group in close proximity (~50 pc) to the s…
HATS-4b: A Dense Hot-Jupiter Transiting a Super Metal-Rich G Star
A. Jordán, R. Brahm, G. Á. Bakos +31
We report the discovery by the HATSouth survey of HATS-4b, an extrasolar planet transiting a V=13.46 mag G star. HATS-4b has a period of P = 2.5167 d, mass of Mp = 1.32 Mj, radius…
Radial velocity variations in the young eruptive star EX Lup
Á. Kóspál, M. Mohler-Fischer, A. Sicilia-Aguilar +7
EX Lup-type objects (EXors) are low-mass pre-main sequence objects characterized by outbursts attributed to highly enhanced disk accretion. The trigger mechanism of EXor outbursts…
The Mass-Radius Relationship for Very Low Mass Stars: Four New Discoveries from the HATSouth Survey
G. Zhou, D. Bayliss, J. D. Hartman +15
We report the discovery of four transiting F-M binary systems with companions between 0.1-0.2 Msun in mass by the HATSouth survey. These systems have been characterised via a globa…
Reanalysis of the FEROS observations of HIP 11952
A. Müller, V. Roccatagliata, Th. Henning +7
Aims. We reanalyze FEROS observations of the star HIP 11952 to reassess the existence of the proposed planetary system. Methods. The radial velocity of the spectra were measured by…
HATS-3b: An inflated hot Jupiter transiting an F-type star
D. Bayliss, G. Zhou, K. Penev +26
We report the discovery by the HATSouth survey of HATS-3b, a transiting extrasolar planet orbiting a V=12.4 F-dwarf star. HATS-3b has a period of P = 3.5479d, mass of Mp = 1.07MJ,…
