The Mass of Kepler-93b and The Composition of Terrestrial Planets
Courtney D. Dressing, David Charbonneau, Xavier Dumusque +32
Kepler-93b is a 1.478 +/- 0.019 Earth radius planet with a 4.7 day period around a bright (V=10.2), astroseismically-characterized host star with a mass of 0.911+/-0.033 solar mass…
Defocussed Transmission Spectroscopy: A potential detection of sodium in the atmosphere of WASP-12b
J. R. Burton, C. A. Watson, P. Rodriguez-Gil +4
We report on a pilot study of a novel observing technique, defocussed transmission spectroscopy, and its application to the study of exoplanet atmospheres using ground-based platfo…
Roche tomography of cataclysmic variables - VI. Differential rotation of AE Aqr - Not tidally locked!
Colin Hill, Christopher Watson, Tariq Shahbaz +2
We present Roche tomograms of the K4V secondary star in the cataclysmic variable AE Aqr, reconstructed from two datasets taken 9 days apart, and measure the differential rotation o…
The Kepler-10 planetary system revisited by HARPS-N: A hot rocky world and a solid Neptune-mass planet
Xavier Dumusque, Aldo S. Bonomo, Raphaelle D. Haywood +31
Kepler-10b was the first rocky planet detected by the Kepler satellite and con- firmed with radial velocity follow-up observations from Keck-HIRES. The mass of the planet was measu…
A Window on Exoplanet Dynamical Histories: Rossiter-McLaughlin Observations of WASP-13b and WASP-32b
R. D. Brothwell, C. A. Watson, G. Hebrard +42
We present Rossiter-McLaughlin observations of WASP-13b and WASP-32b and determine the sky-projected angle between the normal of the planetary orbit and the stellar rotation axis (…
The spotty donor star in the X-ray transient Cen X-4
T. Shahbaz, C. A. Watson, V. S. Dhillon
We accurately determine the fundamental system parameters of the neutron-star X-ray transient Cen X-4 solely using phase-resolved high-resolution UVES spectroscopy. We first determ…
