WTS-1 b - Transiting hot Jupiter around a K-type star

I report on the discovery of WTS-1 b, a hot Jupiter orbiting a mid K-dwarf (~K3V) in a tight 1-day orbit. It is the first planet orbiting a relatively cool star to be found with the WFCAM Transit Survey (WTS). The WTS is a large-scale, infrared photometric monitoring campaign of a vast sample of low-mass stars using the 3.8-m United Kingdom InfraRed Telescope (UKIRT). The survey operates in a unique harmony with the UKIRT observing queue schedule by observing only in poor sky conditions that other programs cannot use. WTS-1 b joins a small sample of giant planets found in very close orbits around stars less massive than the Sun, in contrast to the Kepler sample, which finds that most planets around these stars are small Neptune-size objects. The short orbital period of WTS-1 b, coupled with the measured rotation period and low-mass of the host star, provides an important observational constraint on the theory of tidal evolution and in-spiral timescales for hot Jupiters, which are expected to depend on spectral type. I will also discuss the current status of the WTS and its recent results in characterising the poorly understood, but observationally favourable, population of M-dwarf exoplanet host stars.

Nice find, Sirius

The EPE hasn't produced a page for this yet, which is odd because I found the aforementioned paper in their bibliography.

We can expect more WTS planets. If no one has a quarrel with it, I'll just rename this thread "WTS results" when that time comes.

Weirdly enough the link now gives the designation as WTS-2 b.

And it's the "first planet orbiting a relatively cool star to be found with the WFCAM Transit Survey" too!
