The spin-orbit angles of the transiting exoplanets WASP-1b, WASP-24b, WASP-38b and HAT-P-8b from Rossiter-McLaughlin observations
E. K. Simpson, D. Pollacco, A. Collier Cameron +18
We present observations of the Rossiter-McLaughlin effect for the transiting exoplanet systems WASP-1, WASP-24, WASP-38 and HAT-P-8, and deduce the orientations of the planetary or…
WASP-38b: A Transiting Exoplanet in an Eccentric, 6.87d Period Orbit
S. C. C. Barros, F. Faedi, A. Collier Cameron +31
We report the discovery of WASP-38b, a long period transiting planet in an eccentric 6.871815 day orbit. The transit epoch is 2455335.92050 +/- 0.00074 (HJD) and the transit durati…
WASP-37b: a 1.8 MJ exoplanet transiting a metal-poor star
E. K. Simpson, F. Faedi, S. C. C. Barros +39
We report on the discovery of WASP-37b, a transiting hot Jupiter orbiting a mv = 12.7 G2-type dwarf, with a period of 3.577471 \pm 0.00001 d, transit epoch T0 = 2455338.6188 \pm 0.…
On the alignment of debris disks and their host stars' rotation axis -implications for spin-orbit misalignment in exoplanetary systems
C. A. Watson, S. P. Littlefair, C. Diamond +5
It has been widely thought that measuring the misalignment angle between the orbital plane of a transiting exoplanet and the spin of its host star was a good discriminator between…
Rotation periods of exoplanet host stars
Elaine Simpson, Sallie Baliunas, Greg Henry +1
The stellar rotation periods of ten exoplanet host stars have been determined using newly analysed Ca II H & K flux records from Mount Wilson Observatory and Stromgren b, y photome…
Estimating the masses of extra-solar planets
C. A. Watson, S. P. Littlefair, A. Collier Cameron +2
All extra-solar planet masses that have been derived spectroscopically are lower limits since the inclination of the orbit to our line-of-sight is unknown except for transiting sys…
Orbital period variations of hot-Jupiters caused by the Applegate effect
C. A. Watson, T. R. Marsh
Several authors have shown that precise measurements of transit time variations of exoplanets can be sensitive to other planetary bodies, such as exo-moons. In addition, the transi…
