Faint source star planetary microlensing: the discovery of the cold gas giant planet OGLE-2014-BLG-0676Lb
N. J. Rattenbury, D. P. Bennett, T. Sumi +85
We report the discovery of a planet --- OGLE-2014-BLG-0676Lb --- via gravitational microlensing. Observations for the lensing event were made by the MOA, OGLE, Wise, RoboNET/LCOGT,…
The Anglo-Australian Planet Search XXV: A Candidate Massive Saturn Analog Orbiting HD 30177
Robert A. Wittenmyer, Jonathan Horner, M. W. Mengel +8
We report the discovery of a second long-period giant planet orbiting HD 30177, a star previously known to host a massive Jupiter analog (HD 30177b: a=3.80.1 au, m sin $i=9.7\…
An Ordered Magnetic Field in the Protoplanetary Disk of AB Aur Revealed by Mid-Infrared Polarimetry
Dan Li, Eric Pantin, Charles M. Telesco +5
Magnetic fields (B-fields) play a key role in the formation and evolution of protoplanetary disks, but their properties are poorly understood due to the lack of observational const…
MagAO Imaging of Long-period Objects (MILO). II. A Puzzling White Dwarf around the Sun-like Star HD 11112
Timothy J. Rodigas, P. Bergeron, Amelie Simon +18
HD 11112 is an old, Sun-like star that has a long-term radial velocity (RV) trend indicative of a massive companion on a wide orbit. Here we present direct images of the source res…
Modelling the Inner Debris Disc of HR 8799
B. Contro, J. Horner, R. A. Wittenmyer +2
In many ways, the HR 8799 planetary system strongly resembles our own. It features four giant planets and two debris belts, analogues to the Asteroid and Edgeworth-Kuiper belts. He…
Gas and dust around A-type stars at tens of Myr:signatures of cometary breakup
J S Greaves, W S Holland, B C Matthews +6
Discs of dusty debris around main-sequence star indicate fragmentation of orbiting planetesimals, and for a few A-type stars, a gas component is also seen that may come from collis…
