    • An ancient extrasolar system with five sub-earth-size planets 

      Ragozzine, Darin A.; Campante, Tiago L.; Barclay, Thomas S.; Swift, Jonathan J.; Huber, Daniel; Adibekyan, V. Zh.; Cochran, William D.; Burke, Christopher J.; Isaacson, Howard T.; Quintana, Elisa V. (2015-01-27)
      The chemical composition of stars hosting small exoplanets (with radii less than four Earth radii) appears to be more diverse than that of gas-giant hosts, which tend to be metal-rich. This implies that small, including ...
    • A DEEP SEARCH for ADDITIONAL SATELLITES AROUND the DWARF PLANET HAUMEA 

      Burkhart, Luke D.; Ragozzine, Darin A.; Brown, Michael E. (2016-05-27)
      Haumea is a dwarf planet with two known satellites, an unusually high spin rate, and a large collisional family, making it one of the most interesting objects in the outer solar system. A fully self-consistent formation ...
    • A DYNAMICAL ANALYSIS of the KEPLER-80 SYSTEM of FIVE TRANSITING PLANETS 

      Macdonald, Mariah G.; Ragozzine, Darin A.; Fabrycky, Daniel C.; Ford, Eric B.; Holman, Matthew J.; Isaacson, Howard T.; Lissauer, Jack Jonathan; Lopez, Eric D.; Mazeh, Tsevi; Rogers, Leslie A. (2016-10)
      Kepler has discovered hundreds of systems with multiple transiting exoplanets which hold tremendous potential both individually and collectively for understanding the formation and evolution of planetary systems. Many of ...
    • KEPLER 453 b - THE 10th KEPLER TRANSITING CIRCUMBINARY PLANET 

      Welsh, William F.; Orosz, Jerome A.; Short, Donald R.; COCHRAN, WILLIAM D.; Endl, Michael; Brugamyer, Erik J.; HAGHIGHIPOUR, NADER; Buchhave, Lars A.; Doyle, Laurance R.; Ragozzine, Darin A. (2015-08-10)
      We present the discovery of Kepler-453 b, a 6.2 RƟ planet in a low-eccentricity, 240.5 day orbit about an eclipsing binary. The binary itself consists of a 0.94 and 0.195 M☉ pair of stars with an orbital period of 27.32 ...
    • KOI-3158: The oldest known system of terrestrial-size planets 

      Campante, Tiago L.; Barclay, Thomas S.; Swift, Jonathan J.; Huber, Daniel; Adibekyan, V. Zh.; Cochran, William D.; Burke, Christopher J.; Isaacson, Howard T.; Quintana, Elisa V.; Ragozzine, Darin A. (2015-09-23)
      The first discoveries of exoplanets around Sun-like stars have fueled efforts to find ever smaller worlds evocative of Earth and other terrestrial planets in the Solar System. While gas-giant planets appear to form ...

    • Planetary candidates observed by Kepler iv: Planet sample from Q1-Q8 (22 months) 

      Ragozzine, Darin A.; Burke, Christopher J.; Bryson, Stephen T.; Mullally, Fergal R.; Rowe, Jason F.; Christiansen, Jessie L.; Thompson, Susan E.; Coughlin, Jeffrey L.; Haas, Michael R.; Batalha, Natalie M. (2014-01-10)
      We provide updates to the Kepler planet candidate sample based upon nearly two years of high-precision photometry (i.e., Q1-Q8). From an initial list of nearly 13,400 threshold crossing events, 480 new host stars are ...
    • TRANSIT TIMING OBSERVATIONS from KEPLER. IX. CATALOG of the FULL LONG-CADENCE DATA SET 

      Holczer, Tomer; Mazeh, Tsevi; Nachmani, Gil; Jontof-Hutter, Daniel S.; Ford, Eric B.; Fabrycky, Daniel C.; Ragozzine, Darin A.; Kane, Mackenzie; Steffen, Jason H. (2016-07)
      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 17 quarters of the mission (ftp://wise-ftp.tau.ac.il/pub/tauttv/TTV/ver-112). ...
