The Pan-Pacific Planet Search. II. Confirmation of a two-planet system around HD 121056

Robert A. Wittenmyer, Liang Wang, Fan Liu +5

Precise radial velocities from the Anglo-Australian Telescope confirm the presence of a rare short-period planet around the K0 giant HD 121056. An independent two-planet solution u…

Embryo impacts and gas giant mergers II: Diversity of Hot Jupiters' internal structure

Shang-Fei Liu, Craig B. Agnor, D. N. C. Lin +1

We consider the origin of compact, short-period, Jupiter-mass planets. We propose that their diverse structure is caused by giant impacts of embryos and super-Earths or mergers wit…

OGLE-2011-BLG-0265Lb: a Jovian Microlensing Planet Orbiting an M Dwarf

J. Skowron, I. -G. Shin, A. Udalski +121

We report the discovery of a Jupiter-mass planet orbiting an M-dwarf star that gave rise to the microlensing event OGLE-2011-BLG-0265. Such a system is very rare among known planet…

Empirical Study of Simulated Two-planet Microlensing Event

Wei Zhu, Andrew Gould, Matthew Penny +2

We undertake the first study of two-planet microlensing models recovered from simulations of microlensing events generated by realistic multi-planet systems in which 292 planetary…

High resolution transmission spectrum of the Earth's atmosphere -- Seeing Earth as an exoplanet using a lunar eclipse

Fei Yan, Robert A. E. Fosbury, Monika G. Petr-Gotzens +5

With the rapid developments in the exoplanet field, more and more terrestrial exoplanets are being detected. Characterising their atmospheres using transit observations will become…

Predictions for Microlensing Planetary Events from Core Accretion Theory

Wei Zhu, Matthew Penny, Shude Mao +2

We conduct the first microlensing simulation in the context of planet formation model. The planet population is taken from the Ida & Lin core accretion model for stars…

Planetary Transit Candidates in the CSTAR Field: Analysis of the 2008 Data

Songhu Wang, Hui Zhang, Ji-Lin Zhou +26

The Chinese Small Telescope ARray (CSTAR) is a group of four identical, fully automated, static 14.5 cm telescopes. CSTAR is located at Dome A, Antarctica and covers 20 square degr…

Broad-band transmission spectrum and K-band thermal emission of WASP-43b as observed from the ground

Guo Chen, Roy van Boekel, Hongchi Wang +6

(Abridged) We observed one transit and one occultation of the hot Jupiter WASP-43b simultaneously in the g'r'i'z'JHK bands using the GROND instrument on the MPG/ESO 2.2-meter teles…
