Abstract | dc.description.abstract | We present results of the photometric campaign for planetary and low-luminosity object transits conducted by the OGLE survey in
2005 season (Campaign #5). About twenty most promising candidates discovered in these data were subsequently verified spectroscopically
with the VLT/FLAMES spectrograph.
One of the candidates, OGLE-TR-211, reveals clear changes of radial velocity with small amplitude of 82 m/sec, varying in phase with
photometric transit ephemeris. Thus, we confirm the planetary nature of the OGLE-TR-211 system. Follow-up precise photometry of
OGLE-TR-211 with VLT/FORS together with radial velocity spectroscopy supplemented with high resolution, high S/N VLT/UVES
spectra allowed us to derive parameters of the planet and host star. OGLE-TR-211b is a hot Jupiter orbiting a F7-8 spectral type dwarf
star with the period of 3.68 days. The mass of the planet is equal to 1.03±0.20 MJup while its radius 1.36 +0.18
−0.09 RJup. The radius is about
20% larger than the typical radius of hot Jupiters of similar mass. OGLE-TR-211b is, then, another example of inflated hot Jupiters –
a small group of seven exoplanets with large radii and unusually small densities – objects being a challenge to the current models of
exoplanets. | en_US |
