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…
HAT-P-44b, HAT-P-45b, and HAT-P-46b: Three Transiting Hot Jupiters in Possible Multi-Planet Systems
J. D. Hartman, G. Á. Bakos, G. Torres +26
We report the discovery by the HATNet survey of three new transiting extrasolar planets orbiting moderately bright (V=13.2, 12.8 and 11.9) stars. The planets have orbital periods o…
Examining the broadband emission spectrum of WASP-19b: A new z band eclipse detection
George Zhou, Lucyna Kedziora-Chudczer, Daniel D. R. Bayliss +1
WASP-19b is one of the most irradiated hot-Jupiters known. Its secondary eclipse is the deepest of all transiting planets, and has been measured in multiple optical and infrared ba…
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,…
A portrait of the extreme Solar System object 2012 DR30
Cs. Kiss, Gy. Szabó, J. Horner +15
2012 DR30 is a recently discovered Solar System object on a unique orbit, with a high eccentricity of 0.9867, a perihelion distance of 14.54 AU and a semi-major axis of 1109 AU, in…
HATS-2b: A transiting extrasolar planet orbiting a K-type star showing starspot activity
M. Mohler-Fischer, L. Mancini, J. D. Hartman +24
We report the discovery of HATS-2b, the second transiting extrasolar planet detected by the HATSouth survey. HATS-2b is moving on a circular orbit around a V=13.6 mag, K-type dwarf…
