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…

The Dawes Review 3: The Atmospheres of Extrasolar Planets and Brown Dwarfs

Jeremy Bailey

The last few years has seen a dramatic increase in the number of exoplanets known and in the range of methods for characterising their atmospheric properties. At the same time, new…

Ks band secondary eclipses of WASP-19b and WASP-43b with the Anglo-Australian Telescope

G. Zhou, D. D. R. Bayliss, L. Kedziora-Chudczer +3

We report new Ks band secondary eclipse observations for the hot-Jupiters WASP-19b and WASP-43b. Using the IRIS2 infrared camera on the Anglo-Australian Telescope (AAT), we measure…

A Spin-Orbit Alignment for the Hot Jupiter HATS-3b

B. C. Addison, C. G. Tinney, D. J. Wright +1

We have measured the alignment between the orbit of HATS-3b (a recently discovered, slightly inflated Hot Jupiter) and the spin-axis of its host star. Data were obtained using the…

Searching for Earth-mass planets around Centauri: precise radial velocities from contaminated spectra

Christoph Bergmann, Michael Endl, John B. Hearnshaw +2

This work is part of an ongoing project which aims to detect terrestrial planets in our neighbouring star system Centauri using the Doppler method. Owing to the small angular s…

GJ 832c: A super-earth in the habitable zone

R. A. Wittenmyer, Mikko Tuomi, R. P. Butler +17

We report the detection of GJ 832c, a super-Earth orbiting near the inner edge of the habitable zone of GJ 832, an M dwarf previously known to host a Jupiter analog in a nearly-cir…

Collisional modelling of the debris disc around HIP 17439

Ch. Schüppler, T. Löhne, A. V. Krivov +3

We present an analysis of the debris disc around the nearby K2 V star HIP 17439. In the context of the Herschel DUNES key programme the disc was observed and spatially resolved in…

Correlations between the stellar, planetary and debris components of exoplanet systems observed by

J. P. Marshall, A. Moro-Martín, C. Eiroa +18

The DEBRIS, DUNES and GT programmes observed 37 exoplanet host stars within 25 pc at 70, 100 and 160 m with the sensitivity to detect far-infrared excess emi…

The Mt John University Observatory Search For Earth-mass Planets In The Habitable Zone Of Alpha Centauri

M. Endl, C. Bergmann, J. Hearnshaw +6

The "holy grail" in planet hunting is the detection of an Earth-analog: a planet with similar mass as the Earth and an orbit inside the habitable zone. If we can find such an Earth…

Planets in Spin-Orbit Misalignment and the Search for Stellar Companions

Brett C. Addison, C. G. Tinney, Duncan J. Wright +3

The discovery of giant planets orbiting close to their host stars was one of the most unexpected results of early exoplanetary science. Astronomers have since found that a signific…

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…

The Anglo-Australian Planet Search. XXIII. Two New Jupiter Analogs

Robert A. Wittenmyer, Jonathan Horner, C. G. Tinney +9

We report the discovery of two long-period giant planets from the Anglo-Australian Planet Search. HD 154857c is in a multiple-planet system, while HD 114613b appears to be solitary…

A Dynamical Investigation of the Proposed BD +20 2457 System

Jonathan Horner, Robert A. Wittenmyer, Tobias C. Hinse +1

We present a detailed dynamical analysis of the orbital stability of the BD +20 2457 system, which features planets or brown dwarfs moving on relatively eccentric orbits. We find t…
