Transiting planets of intermediate-mass stars
Abstract
In contrast to planets of solar-like stars, very little is known about
close-in planets of intermediate-mass stars
($M_* = 1.3-2.1 M_{\rm \odot}$).
Detecting close-in planets of intermediate-mass main-sequence stars
would show that the formation and migration time of planets must be
short, because the life-time of the proto-planetary disks of such stars
is short.
The detection of such planets would also put strong constraints on the
evaporation rate of planets.
Using data obtained with CoRoT we have identified transiting
Jupiter-like planet candidates with short orbital periods.
We subsequently observed these candidates with the SANDIFORD Echelle
spectrograph on the 2.1-m telescope at McDonald observatory, CAFE on the
2.2-m telescope at Calar Alto, FIES on the 2.6-m NOT telescope at Roque
de Los Muchachos Observatory, and HIRES on the Keck telescope.
In this talk we will be presenting the first results of our survey and
showing that close-in planets around intermediate-mass main-sequence
stars can be detected if their mass is $M_p \geq 2 M_{\rm Jup}$ and
orbital period $P\leq 4\,{\rm d}$.
