Stellar Spin-Orbit Misalignment in a Multiplanet System

Daniel Huber, Joshua A. Carter, Mauro Barbieri +32

Stars hosting hot Jupiters are often observed to have high obliquities, whereas stars with multiple co-planar planets have been seen to have low obliquities. This has been interpre…

Kepler White Paper: Asteroseismology of Solar-Like Oscillators in a 2-Wheel Mission

W. J Chaplin, H. Kjeldsen, J. Christensen-Dalsgaard +53

We comment on the potential for continuing asteroseismology of solar-type and red-giant stars in a 2-wheel Kepler Mission. Our main conclusion is that by targeting stars in the ecl…

High-precision photometry by telescope defocussing. V. WASP-15 and WASP-16

J. Southworth, L. Mancini, P. Browne +40

We present new photometric observations of WASP-15 and WASP-16, two transiting extrasolar planetary systems with measured orbital obliquities but without photometric follow-up sinc…

Physical properties, transmission and emission spectra of the WASP-19 planetary system from multi-colour photometry

L. Mancini, S. Ciceri, G. Chen +43

We present new ground-based, multi-colour, broad-band photometric measurements of the physical parameters, transmission and emission spectra of the transiting extrasolar planet WAS…

A sub-Mercury-sized exoplanet

Thomas Barclay, Jason F. Rowe, Jack J. Lissauer +55

Since the discovery of the first exoplanet we have known that other planetary systems can look quite unlike our own. However, until recently we have only been able to probe the upp…

Estimating the parameters of globular cluster M 30 (NGC 7099) from time-series photometry

N. Kains, D. M. Bramich, A. Arellano Ferro +47

We present the analysis of 26 nights of V and I time-series observations from 2011 and 2012 of the globular cluster M 30 (NGC 7099). We used our data to search for variable stars i…

Fundamental Properties of Kepler Planet-Candidate Host Stars using Asteroseismology

Daniel Huber, William J. Chaplin, Jørgen Christensen-Dalsgaard +31

We have used asteroseismology to determine fundamental properties for 66 Kepler planet-candidate host stars, with typical uncertainties of 3% and 7% in radius and mass, respectivel…

Microlensing Discovery of a Population of Very Tight, Very Low-mass Binary Brown Dwarfs

J. -Y. Choi, C. Han, A. Udalski +121

Although many models have been proposed, the physical mechanisms responsible for the formation of low-mass brown dwarfs are poorly understood. The multiplicity properties and minim…

A Giant Planet beyond the Snow Line in Microlensing Event OGLE-2011-BLG-0251

N. Kains, R. Street, J. -Y. Choi +128

We present the analysis of the gravitational microlensing event OGLE-2011-BLG-0251. This anomalous event was observed by several survey and follow-up collaborations conducting micr…

Asteroseismic determination of obliquities of the exoplanet systems Kepler-50 and Kepler-65

W. J. Chaplin, R. Sanchis-Ojeda, T. L. Campante +26

Results on the obliquity of exoplanet host stars -- the angle between the stellar spin axis and the planetary orbital axis -- provide important diagnostic information for theories…

Kepler-68: Three Planets, One With a Density Between That of Earth and Ice Giants

Ronald L. Gilliland, Geoffrey W. Marcy, Jason F. Rowe +30

NASA's Kepler Mission has revealed two transiting planets orbiting Kepler-68. Follow-up Doppler measurements have established the mass of the innermost planet and revealed a third…
