Abstract:
We report on the confirmation of a transiting giant planet around the
relatively hot (Teff=6801±56K) star HD 2685, whose transit signal
was detected in Sector 1 data of NASA's TESS mission. We confirmed the
planetary nature of the transit signal using Doppler velocimetric
measurements with CHIRON, CORALIE, and FEROS, as well as using
photometric data obtained with the Chilean-Hungarian Automated
Telescope and the Las Cumbres Observatory. From the joint analysis of
photometry and radial velocities, we derived the following parameters
for HD 2685b: P=4.12688+0.00005-0.00004-days,
e=0.091+0.039-0.047, MP=1.17±0.12MJ, and
RP=1.44±0.05RJ. This system is a typical example of an inflated
transiting hot Jupiter in a low-eccentricity orbit. Based on the
apparent visual magnitude (V=9.6mag) of the host star, this is one of
the brightest known stars hosting a transiting hot Jupiter, and it is
a good example of the upcoming systems that will be detected by TESS
during the two-year primary mission. This is also an excellent target
for future ground- and space-based atmospheric characterization as
well as a good candidate for measuring the projected spin-orbit
misalignment angle through the Rossiter-McLaughlin effect.
