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\…
ACCESS I: An Optical Transmission Spectrum of GJ 1214b Reveals a Heterogeneous Stellar Photosphere
Benjamin Rackham, Néstor Espinoza, Dániel Apai +8
GJ 1214b is the most studied sub-Neptune exoplanet to date. Recent measurements have shown its near-infrared transmission spectrum to be flat, pointing to a high-altitude opacity s…
A New M Dwarf Debris Disk Candidate in a Young Moving Group Discovered with Disk Detective
Steven M. Silverberg, Marc J. Kuchner, John P. Wisniewski +15
We used the Disk Detective citizen science project and the BANYAN II Bayesian analysis tool to identify a new candidate member of a nearby young association with infrared excess. W…
A terrestrial planet candidate in a temperate orbit around Proxima Centauri
Guillem Anglada-Escudé, Pedro J. Amado, John Barnes +28
At a distance of 1.295 parsecs, the red-dwarf Proxima Centauri ( Centauri C, GL 551, HIP 70890, or simply Proxima) is the Sun's closest stellar neighbor and one of the best stud…
Imaging protoplanets: observing transition disks with non-redundant masking
Steph Sallum, Josh Eisner, Laird M. Close +17
Transition disks, protoplanetary disks with inner clearings, are promising objects in which to directly image forming planets. The high contrast imaging technique of non-redundant…
The Magellan PFS Planet Search Program: Radial Velocity and Stellar Abundance Analyses of the 360 AU, Metal-Poor Binary "Twins" HD 133131A & B
Johanna K. Teske, Stephen A. Shectman, Steve S. Vogt +5
We present a new precision radial velocity (RV) dataset that reveals multiple planets orbiting the stars in the 360 AU, G2G2 "twin" binary HD 133131AB. Our 6 years of high…
