A white dwarf bound to the transiting planetary system WASP-98
John Southworth, P. -E. Tremblay, B. T. Gaensicke +2
WASP-98 is a planetary system containing a hot Jupiter transiting a late-G dwarf. A fainter star 12 arcsec distant has previously been identified as a white dwarf, with a distance…
A multiplicity study of transiting exoplanet host stars. II. Revised properties of transiting planetary systems with companions
J. Southworth, A. J. Bohn, M. A. Kenworthy +2
We perform a detailed study of six transiting planetary systems with relatively bright stars close enough to affect observations of these systems. Light curves are analysed taking…
A multiplicity study of transiting exoplanet host stars. I. High-contrast imaging with VLT/SPHERE
A. J. Bohn, J. Southworth, C. Ginski +3
We study the multiplicity of host stars to known transiting extra-solar planets to test competing theories on the formation mechanisms of hot Jupiters. We observed 45 exoplanet hos…
The EBLM Project VI. The mass and radius of five low-mass stars in F+M binaries discovered by the WASP survey
S. Gill, P. F. L. Maxted, J. A. Evans +27
Some M-dwarfs around F-/G-type stars have been measured to be hotter and larger than predicted by stellar evolution models. Inconsistencies between observations and models need add…
Spitzer Microlensing parallax reveals two isolated stars in the Galactic bulge
Weicheng Zang, Yossi Shvartzvald, Tianshu Wang +90
We report the mass and distance measurements of two single-lens events from the 2017 Spitzer microlensing campaign. The ground-based observations yield the detection of finite-sour…
OGLE-2017-BLG-1186: first application of asteroseismology and Gaussian processes to microlensing
Shun-Sheng Li, Weicheng Zang, Andrzej Udalski +102
We present the analysis of the event OGLE-2017-BLG-1186 from the 2017 Spitzer microlensing campaign. This is a remarkable microlensing event because its source is photometrically b…
