Abstract:
Accurate and repeated photometric follow-up observations of planetary
transit events are important to precisely characterize the physical
properties of exoplanets. A good knowledge of the main characteristics
of the exoplanets is fundamental in order to trace their origin and
evolution. Multi-band photometric observations play an important role
in this process.
By using new photometric data, we computed precise estimates of the
physical properties of two transiting planetary systems at equilibrium
temperatures of ∼2000K.
We present new broadband, multi-colour photometric observations
obtained using three small class telescopes and the
telescope-defocussing technique. In particular we obtained 11 and 10
light curves covering 8 and 7 transits of HAT-P-23 and WASP-48,
respectively. For each of the two targets, one transit event was
simultaneously observed through four optical filters. One transit of
WASP-48 b was monitored with two telescopes from the same
observatory. The physical parameters of the systems were obtained by
fitting the transit light curves with jktebop and from published
spectroscopic measurements.
Description:
Files contain the data used to plot the lightcurves in Fig. 2, 3, 4 and
5 in the paper. The data were obtained using three different
facilities, one at the Loiano observatory and two at the Calar Alto
observatory.
