Evolution from protoplanetary to debris discs: The transition disc around HD 166191
G. M. Kennedy, S. J. Murphy, C. M. Lisse +12
HD 166191 has been identified by several studies as hosting a rare and extremely bright warm debris disc with an additional outer cool disc component. However, an alternative inter…
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…
A Nearly Polar Orbit for the Extrasolar Hot Jupiter WASP-79b
B. C. Addison, C. G. Tinney, D. J. Wright +5
We report the measurement of a spin-orbit misalignment for WASP-79b, a recently discovered, bloated transiting hot Jupiter from the WASP survey. Data were obtained using the CYCLOP…
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,…
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…
Spectroscopic Observations of SN 2012fr: A Luminous Normal Type Ia Supernova with Early High Velocity Features and Late Velocity Plateau
M. J. Childress, R. A. Scalzo, S. A. Sim +55
We present 65 optical spectra of the Type Ia supernova SN 2012fr, of which 33 were obtained before maximum light. At early times SN 2012fr shows clear evidence of a high-velocity f…
