Very Low-Mass Stellar and Substellar Companions to Solar-like Stars From MARVELS VI: A Giant Planet and a Brown Dwarf Candidate in a Close Binary System HD 87646
Bo Ma, Jian Ge, Alex Wolszczan +34
We report the detections of a giant planet (MARVELS-7b) and a brown dwarf candidate (MARVELS-7c) around the primary star in the close binary system, HD 87646. It is the first close…
A Dynamical Analysis of the Kepler-80 System of Five Transiting Planets
Mariah G. MacDonald, Darin Ragozzine, Daniel C. Fabrycky +10
Kepler has discovered hundreds of systems with multiple transiting exoplanets which hold tremendous potential both individually and collectively for understanding the formation and…
Transit Timing Observations from Kepler. IX. Catalog of the Full Long-Cadence Data Set
Tomer Holczer, Tsevi Mazeh, Gil Nachmani +6
We present a new transit timing catalog of 2599 Kepler Objects of Interest (=KOIs), using the PDC-MAP long-cadence light curves that include the full seventeen quarters of the miss…
Masses of the components of SB2 binaries observed with Gaia. III. Accurate SB2 orbits for 10 binaries and masses of HIP 87895
Flavien Kiefer, Jean-Louis Halbwachs, Frédéric Arenou +9
In anticipation of the Gaia astrometric mission, a large sample of spectroscopic binaries has been observed since 2010 with the SOPHIE spectrograph at the Haute--Provence Observato…
Dearth of short-period Neptunian exoplanets - a desert in period-mass and period-radius planes
Tsevi Mazeh, Tomer Holczer, Simchon Faigler
A few studies have reported a significant dearth of exoplanets with Neptune mass and radius with orbital periods below -- d. This cannot be explained by observational biases…
