Planet Hunters: A Transiting Circumbinary Planet in a Quadruple Star System
Megan E. Schwamb, Jerome A. Orosz, Joshua A. Carter +17
We report the discovery and confirmation of a transiting circumbinary planet (PH1b) around KIC 4862625, an eclipsing binary in the Kepler field. The planet was discovered by volunt…
Physical Parameters of Asteroids Estimated from the WISE 3 Band Data and NEOWISE Post-Cryogenic Survey
A. Mainzer, T. Grav, J. Masiero +7
Enhancements to the science data processing pipeline of NASA's Wide-field Infrared Explorer (WISE) mission, collectively known as NEOWISE, resulted in the detection of 158,000 m…
A Common Proper Motion Stellar Companion to HAT-P-7
Norio Narita, Yasuhiro H. Takahashi, Masayuki Kuzuhara +51
We report that HAT-P-7 has a common proper motion stellar companion. The companion is located at arcsec to the east and estimated as an M5.5V dwarf based on its colors. W…
Faint moving object detection, and the Low Signal-to-Noise recovery of Main Belt comet P/2008 R1 Garradd
Jan Kleyna, Karen J. Meech, Olivier Hainaut
We describe the recovery of faint Main Belt comet P/2008 R1 Garradd using several telescopes, culminating in a successful low recovery with the Gemini North telescope with GM…
The Nucleus of Main-Belt Comet 259P/Garradd
Eric MacLennan, Henry Hsieh
We present observations of the main-belt comet 259P/Garradd, previously known as P/2008 R1 (Garradd), obtained in 2011 and 2012 using the Gemini North Telescope on Mauna Kea in Haw…
