Abstract:
The radii of giant planets, as measured from transit observations, may
vary with wavelength due to Rayleigh scattering or variations in
opacity. Such an effect is predicted to be large enough to detect
using ground-based observations at multiple wavelengths. We present
the defocused photometry of a transit in the HAT-P-5 system, obtained
simultaneously through Stroemgren u, Gunn g and r, and Johnson I
filters. Two more transit events were observed through a Gunn r
filter.
Description:
We observed one full transit of HAT-P-5 on the night of 2010 August
23, using the 2.2-m telescope and BUSCA imager at Calar Alto
Astronomical Observatory. BUSCA uses dichroics to split the incoming
light into four wavelength intervals, which traverse different arms of
the instrument and are incident on to four CCDs.
We observed two transits of HAT-P-5 in 2011 May and July, using BFOSC
mounted on the 1.52-m G.D. Cassini Telescope at Loiano Observatory,
Italy.
