Single Transit Candidates from K2: Detection and Period Estimation

H. P. Osborn, D. J. Armstrong, D. J. A. Brown +9

Photometric surveys such as Kepler have the precision to identify exoplanet and eclipsing binary candidates from only a single transit. K2, with its 75d campaign duration, is ideal…

ALMA Observations of a Gap and a Ring in the Protoplanetary Disk around TW Hya

Hideko Nomura, Takashi Tsukagoshi, Ryohei Kawabe +8

We report the first detection of a gap and a ring in 336 GHz dust continuum emission from the protoplanetary disk around TW Hya, using the Atacama Large Millimeter/Submillimeter Ar…

The global impact distribution of Near-Earth objects

Clemens Rumpf, Hugh G. Lewis, Peter M. Atkinson

Asteroids that could collide with the Earth are listed on the publicly available Near-Earth object (NEO) hazard web sites maintained by the US and European space agencies (NASA and…

The Kepler-454 System: A Small, Not-rocky Inner Planet, a Jovian World, and a Distant Companion

Sara Gettel, David Charbonneau, Courtney D. Dressing +47

Kepler-454 (KOI-273) is a relatively bright (V = 11.69 mag), Sun-like starthat hosts a transiting planet candidate in a 10.6 d orbit. From spectroscopy, we estimate the stellar tem…

WASP-135b: a highly irradiated, inflated hot Jupiter orbiting a G5V star

Jessica J. Spake, David J. A. Brown, Amanda P. Doyle +27

We report the discovery of a new transiting planet from the WASP survey. WASP-135b is a hot Jupiter with a radius of 1.30 pm 0.09 Rjup, a mass of 1.90 pm 0.08 Mjup and an orbital p…

2P/Encke, the Taurid complex NEOs and the Maribo and Sutter's Mill meteorites

C. Tubiana, C. Snodgrass, R. Michelsen +4

The Taurid meteoroid stream has long been linked with 2P/Encke owing to a good match of their orbital elements, even though the comet's activity is not strong enough to explain the…

The Host Stars of Keplers Habitable Exoplanets: Superflares, Rotation and Activity

D. J. Armstrong, C. E. Pugh, A. -M. Broomhall +4

We embark on a detailed study of the lightcurves of Keplers most Earth-like exoplanet host stars using the full length of Kepler data. We derive rotation periods, photometric activ…

The Outer Solar System Origins Survey: I. Design and First-Quarter Discoveries

Michele T. Bannister, J. J. Kavelaars, Jean-Marc Petit +36

We report the discovery, tracking and detection circumstances for 85 trans-Neptunian objects (TNOs) from the first 42 deg of the Outer Solar System Origins Survey (OSSOS). Th…

The HARPS-N Rocky Planet Search I. HD219134b: A transiting rocky planet in a multi-planet system at 6.5 pc from the Sun

F. Motalebi, S. Udry, M. Gillon +36

We present here the detection of a system of four low-mass planets around the bright (V=5.5) and close-by (6.5 pc) star HD219134. This is the first result of the Rocky Planet Searc…

Sputtering of Oxygen Ice by Low Energy Ions

E. A. Muntean, P. Lacerda, T. A. Field +3

Naturally occurring ices lie on both interstellar dust grains and on celestial objects, such as those in the outer solar system. These ices are continu- ously subjected to irradiat…

Prospects for detecting decreasing exoplanet frequency with main sequence age using PLATO

Dimitri Veras, David J. A. Brown, Alexander J. Mustill +1

The space mission PLATO will usher in a new era of exoplanetary science by expanding our current inventory of transiting systems and constraining host star ages, which are currentl…

Absolute magnitudes and slope parameters for 250,000 asteroids observed by Pan-STARRS PS1 - preliminary results

Peter Vereš, Robert Jedicke, Alan Fitzsimmons +14

We present the results of a Monte Carlo technique to calculate the absolute magnitudes (H) and slope parameters (G) of about 240000 asteroids observed by the Pan-STARRS1 telescope…

Modelling the brightness increase signature due to asteroid collisions

Ev McLoughlin, Alan Fitzsimmons, Alan McLoughlin

We have developed a model to predict the post-collision brightness increase of sub-catastrophic collisions between asteroids and to evaluate the likelihood of a survey detecting th…

Sublimation-Driven Activity in Main-Belt Comet 313P/Gibbs

Henry H. Hsieh, Olivier Hainaut, Bojan Novakovic +15

We present an observational and dynamical study of newly discovered main-belt comet 313P/Gibbs. We find that the object is clearly active both in observations obtained in 2014 and…
