HD 106906 b: A planetary-mass companion outside a massive debris disk
Vanessa Bailey, Tiffany Meshkat, Megan Reiter +14
We report the discovery of a planetary-mass companion, HD 106906 b, with the new Magellan Adaptive Optics (MagAO) + Clio2 system. The companion is detected with Clio2 in three band…
A Detailed Analysis of the HD 73526 2:1 Resonant Planetary System
Robert A. Wittenmyer, Xianyu Tan, Man Hoi Lee +15
We present six years of new radial-velocity data from the Anglo-Australian and Magellan Telescopes on the HD 73526 2:1 resonant planetary system. We investigate both Keplerian and…
De-biased Populations of Kuiper Belt Objects from the Deep Ecliptic Survey
E. R. Adams, A. A. S. Gulbis, J. L. Elliot +4
The Deep Ecliptic Survey (DES) discovered hundreds of Kuiper Belt objects from 1998-2005. Follow-up observations yielded 304 objects with good dynamical classifications (Classical,…
A dynamically-packed planetary system around GJ667C with three super-Earths in its habitable zone
Guillem Anglada-Escudé, Mikko Tuomi, Enrico Gerlach +8
Since low-mass stars have low luminosities, orbits at which liquid water can exist on Earth-sized planets are relatively close-in, which produces Doppler signals that are detectabl…
A Combined VLT and Gemini Study of the Atmosphere of the Directly-Imaged Planet, beta Pictoris b
Thayne Currie, Adam Burrows, Nikku Madhusudhan +10
We analyze new/archival VLT/NaCo and Gemini/NICI high-contrast imaging of the young, self-luminous planet Pictoris b in seven near-to-mid IR photometric filters, using advanced…
Two planetary companions around the K7 dwarf GJ 221 : a hot super-Earth and a candidate in the sub-Saturn desert range
Pamela Arriagada, Guillem Anglada-Escudé, R. Paul Butler +5
We report two low mass companions orbiting the nearby K7 dwarf GJ 221 that have emerged from re-analyzing 4.4 years of publicly available HARPS spectra complemented with 2 years of…
