Abstract:
WASP-80 is one of only two systems known to contain a hot Jupiter
which transits its M-dwarf host star. We present eight light curves of
one transit event, obtained simultaneously using two defocussed
telescopes. These data were taken through the Bessell I, Sloan
g'r'i'z' and near-infrared JHK passbands. We use our data to search
for opacity-induced changes in the planetary radius, but find that all
values agree with each other. Our data are therefore consistent with a
flat transmission spectrum to within the observational uncertainties.
We also measure an activity index of the host star of
logR'_HK=-4.495, meaning that WASP-80A shows strong chromospheric
activity. The non-detection of starspots implies that, if they exist,
they must be small and symmetrically distributed on the stellar
surface. We model all available optical transit light curves and
obtain improved physical properties and orbital ephemerides for the
system.
Description:
8 light curves of one transit of the extrasolar planetary system
WASP-80, observed on 2013 June 16, are presented.
Seven of the datasets were obtained using the MPG/ESO 2.2-m telescope,
GROND camera and filters similar to Sloan g', r', i', z', and J, H, K
at the ESO Observatory in La Silla (Chile).
Another data set was obtained using the 1.54-m Danish telescope, DFOSC
camera and Bessel-i filter at La Silla (Chile).
