Abstract:
We obtained low-resolution, multi-object spectra of the planet host
star HAT-P-32 and multiple comparison stars during a transit event of
HAT-P-32b. The spectral flux was binned in 62 narrow channels from
3300 to 10000Å and used to create differential photometric light
curves. These light curves were analysed for a wavelength dependence
of the effective planetary radius.
Description:
A set of 62 simultaneous photometric light curves from 3300 to
10000Å of a transit event of HAT-P-32b. The wavelength range of
each light curve is ∼100Å in average. The light curves cover about
one hour pre-transit, the transit event, and about 1 hour
post-transit. Observations have been taken with MODS at LBT in
multi-object mode. Light curves are given in differential magnitudes.
