Abstract:
We report the discovery of a new transiting planet in the southern
hemisphere. It was found by the WASP-south transit survey and
confirmed photometrically and spectroscopically by the 1.2m Swiss
Euler telescope, LCOGT 2m Faulkes South Telescope, the 60cm TRAPPIST
telescope, and the ESO 3.6m telescope. The orbital period of the
planet is 2.94 days. We find that it is a gas giant with a mass of
0.88±0.10MJ and an estimated radius of 0.96±0.05RJ. We
obtained spectra during transit with the HARPS spectrograph and detect
the Rossiter-McLaughlin effect despite its small amplitude.
Description:
The data is composed of 7 photometric timeseries and 2 set of radial
velocities. 2 photometric timeseries originate from the WASP-South
instrument, 2 from the Euler Telescope, 1 from the FTS telescope, 2
from the TRAPPIST telescope. The RVs come from the CORALIE
spectrograph on the Euler Telescope, and from HARPS, on the ESO 3.6m
They give evidence for the presence of a planet around WASP-23.
