Estimating Stellar Radial Velocity Variability from Kepler and GALEX: Implications for the Radial Velocity Confirmation of Exoplanets
H. M. Cegla, K. G. Stassun, C. A. Watson +2
We cross-match the GALEX and Kepler surveys to create a unique dataset with both ultraviolet (UV) measurements and highly precise photometric variability measurements in the visibl…
An Earth-sized planet with an Earth-like density
Francesco Pepe, Andrew Collier Cameron, David W. Latham +31
Kepler-78 (KIC 8435766) was identified by Sanchis-Ojeda et al. (2013) as harbouring a transiting planet of 1.16 times the size of the Earth and an orbital period of only 8.5 hours.…
Direct Imaging Detection of Methane in the Atmosphere of GJ 504 b
M. Janson, T. Brandt, M. Kuzuhara +54
Most exoplanets detected by direct imaging so far have been characterized by relatively hot (> ~1000 K) and cloudy atmospheres. A surprising feature in some of their atmospheres ha…
Meteor Showers on Earth from Sungrazing Comets
A. Sekhar, D. J. Asher
Sungrazing comets have always captured a lot of interest and curiosity among the general public as well as scientists since ancient times. The perihelion passage of comet C/2012 S1…
Outgassing Behavior of C/2012 S1 (ISON) From September 2011 to June 2013
Karen J. Meech, Bin Yang, Jan Kleyna +26
We report photometric observations for comet C/2012 S1 (ISON) obtained during the time period immediately after discovery (r=6.28 AU) until it moved into solar conjunction in mid-2…
Thermal Properties, Sizes, and Size Distribution of Jupiter-Family Cometary Nuclei
Y. R. Fernandez, M. S. Kelley, P. L. Lamy +14
We present results from SEPPCoN, an on-going Survey of the Ensemble Physical Properties of Cometary Nuclei. In this report we discuss mid-infrared measurements of the thermal emiss…
Discovery of WASP-65b and WASP-75b: Two Hot Jupiters Without Highly Inflated Radii
Y. Gómez Maqueo Chew, F. Faedi, D. Pollacco +38
We report the discovery of two transiting hot Jupiters, WASP-65b (M_pl = 1.55 +/- 0.16 M_J; R_pl = 1.11 +/- 0.06 R_J), and WASP-75b (M_pl = 1.07 +/- 0.05 M_J; R_pl = 1.27 +/- 0.05…
Main-Belt Comet P/2012 T1 (PANSTARRS)
Henry H. Hsieh, Heather M. Kaluna, Bojan Novakovic +25
We present initial results from observations and numerical analyses aimed at characterizing main-belt comet P/2012 T1 (PANSTARRS). Optical monitoring observations were made between…
Saturnian mean motion resonances in meteoroid streams
Aswin Sekhar, David J. Asher
Many previous works have shown the relevance and dynamics of Jovian mean motion resonances (MMR) in various meteoroid streams. These resonant swarms are known to have produced spec…
Lucky Imaging of transiting planet host stars with LuckyCam
F. Faedi, T. Staley, Y. Gomez Maqueo Chew +7
We obtained high-resolution, high-contrast optical imaging in the SDSS band with the LuckyCam camera mounted on the 2.56m Nordic Optical Telescope, to search for faint stellar…
CHEOPS: A Transit Photometry Mission for ESA's Small Mission Programme
C. Broeg, A. Fortier, D. Ehrenreich +18
Ground based radial velocity (RV) searches continue to discover exoplanets below Neptune mass down to Earth mass. Furthermore, ground based transit searches now reach milli-mag pho…
TNOs are Cool: A survey of the trans-Neptunian region. VIII. Combined Herschel PACS and SPIRE observations of 9 bright targets at 70--500 micron
S. Fornasier, E. Lellouch, T. Müller +17
Transneptunian objects (TNOs) are bodies populating the Kuiper Belt and they are believed to retain the most pristine and least altered material of the solar system. The Herschel O…
The Persistent Activity of Jupiter-Family Comets at 3 to 7 AU
Michael S. Kelley, Yanga R. Fernandez, Javier Licandro +14
We present an analysis of comet activity based on the Spitzer Space Telescope component of the Survey of the Ensemble Physical Properties of Cometary Nuclei. We show that the surve…
Analysis of spin-orbit alignment in the WASP-32, WASP-38, and HAT-P-27/WASP-40 systems
D. J. A. Brown, A. Collier Cameron, R. F. Díaz +14
We present measurements of the spin-orbit alignment angle, lambda, for the hot Jupiter systems WASP-32, WASP-38, and HAT-P-27/WASP-40, based on data obtained using the HARPS spectr…
Resonant Behavior of Comet Halley and the Orionid Stream
Aswin Sekhar, David J Asher
Comet 1P/Halley has the unique distinction of having a very comprehensive set of observational records for almost every perihelion passage from 240 B.C. This has helped to constrai…
The Next Generation Transit Survey (NGTS)
Peter J. Wheatley, Don L. Pollacco, Didier Queloz +19
The Next Generation Transit Survey (NGTS) is a new ground-based sky survey designed to find transiting Neptunes and super-Earths. By covering at least sixteen times the sky area of…
The Homogeneous Study of Transiting Systems (HoSTS) I. The Pilot Study of WASP-13
Y. Gómez Maqueo Chew, F. Faedi, P. Cargile +13
We present the fundamental stellar and planetary properties of the transiting planetary system WASP-13 within the framework of the Homogeneous Study of Transiting Systems (HoSTS).…
Transit timing variations in WASP-10b induced by stellar activity?
S. C. C. Barros, G. Boue, N. P. Gibson +5
The hot-Jupiter WASP-10b was reported by Maciejewski et al. (2011a,b) to show transit timing variations (TTV) with an amplitude of ~ 3.5 minutes. These authors proposed that the ob…
Finding Exoplanets Orbiting Young Active Stars. I. Technique
V. E. Moulds, C. A. Watson, X. Bonfils +2
Stellar activity, such as starspots, can induce radial velocity (RV) variations that can mask or even mimic the RV signature of orbiting exoplanets. For this reason RV exoplanet su…
