A Four-Planet System Orbiting The K0V Star HD 141399

Vogt, Steven S.; Butler, R. Paul; Rivera, Eugenio J.; Kibrick, Robert; Burt, Jennifer; Hanson, Russell; Meschiari, Stefano; Henry, Gregory W.; Laughlin, Gregory (2014-06)

We present precision radial velocity (RV) data sets from Keck-HIRES and from Lick Observatory's new Automated Planet Finder Telescope and Levy Spectrometer on Mt. Hamilton that reveal a multiple-planet system orbiting the ...

Transiting Exoplanets From The CoRoT Space Mission: XXVI. CoRoT-24: a transiting multiplanet system

Alonso, R.; Moutou, C.; Endl, M.; Almenara, J. M.; Guenther, E. W.; Deleuil, M.; Hatzes, A.; Aigrain, S.; Auvergne, M.; Baglin, A.; Barge, P.; Bonomo, A. S.; Borde, P.; Bouchy, F.; Cavarroc, C.; Cabrera, J.; Carpano, S.; Csizmadia, S.; Cochran, W. D.; Deeg, H. J.; Diaz, R. F.; Dvorak, R.; Erikson, A.; Ferraz-Mello, S.; Fridlund, M.; Fruth, T.; Gandolfi, D.; Gillon, M.; Grziwa, S.; Guillot, T.; Hebrard, G.; Jorda, L.; Leger, A.; Lammer, H.; Lovis, C.; MacQueen, P. J.; Mazeh, T.; Ofir, A.; Olivier, M.; Pasternacki, T.; Patzold, M.; Queloz, D.; Rauer, H.; Rouan, D.; Santerne, A.; Schneider, J.; dos Santos, M. T.; Tingley, B.; Titz-Weider, R.; Weingrill, J.; Wuchterl, G. (2014-07)

We present the discovery of a candidate multiply transiting system, the first one found in the CoRoT mission. Two transit like features with periods of 5.11 and 11.76 d are detected in the CoRoT light curve around a main ...

Kepler-424 B: A "Lonely" Hot Jupiter That Found A Companion

Endl, Michael; Caldwell, Douglas A.; Barclay, Thomas; Huber, Daniel; Isaacson, Howard; Buchhave, Lars A.; Brugamyer, Erik; Robertson, Paul; Cochran, William D.; MacQueen, Phillip J.; Havel, Mathieu; Lucas, Phillip; Howell, Steve B.; Fischer, Debra; Quintana, Elisa; Ciardi, David R. (2014-11)

Hot Jupiter systems provide unique observational constraints for migration models in multiple systems and binaries. We report on the discovery of the Kepler-424 (KOI-214) two-planet system, which consists of a transiting ...

High Precision Abundances in the 16 Cyg Binary System: A Signature of the Rocky Core in the Giant Planet

Maia, Marcelo Tucci; Melendez, Jorge; Ramirez, Ivan (2014-08)

We study the stars of the binary system 16 Cygni to determine with high precision their chemical composition. Knowing that the component B has a detected planet of at least 1.5 Jupiter masses, we investigate if there are ...

Astrometry, Radial Velocity, And Photometry: The Hd 128311 System Remixed With Data From Hst, Het, And Apt

McArthur, Barbara E.; Benedict, G. Fritz; Henry, Gregory W.; Hatzes, Artie; Cochran, William D.; Harrison, Thomas E.; Johns-Krull, Chris; Nelan, Ed (2014-11)

We have used high-cadence radial velocity measurements from the Hobby-Eberly Telescope with published velocities from the Lick 3 m Shane Telescope, combined with astrometric data from the Hubble Space Telescope (HST) Fine ...
