Abstract:
We present ground-based optical observations of the 2009 September and
2010 January transits of HD 80606b. Based on three partial light
curves of the 2009 September event, we derive a midtransit time of
Tc[HJD]=2455099.196±0.026, which is about 1σ away from the
previously predicted time. We observed the 2010 January event from
nine different locations, with most phases of the transit being
observed by at least three different teams. We determine a midtransit
time of Tc[HJD]=2455210.6502±0.0064, which is within 1.3σ of
the time derived from a Spitzer observation of the same event.
Description:
The new data presented in this paper are three photometric time series
spanning the first portion of the transit of 2009 September 23/24,
based on observations across North America; and ten photometric time
series spanning the entire transit of 2010 January 13/14, based on
data from Israel (Wise Observatory 1.0m, Z filter), Europe
(Observatoire de Haute Provence 1.2m, Gunn-r), Canary Islands (Gran
Telescopio Canarias 10.4m, i'), North America (AO 0.41m (I), RHO 0.76m
(i'), FLWO 1.2m (i'), TMO 1.0m (i'), WAO 0.36m (I) and MLO 1.0m (i')),
and Hawaii (Faulkes Telescope North 2.0m (Z)). In all cases, we
gathered CCD images encompassing the target star, HD 80606 (G5V,
V=9.06, B-V=0.76), and its visual binary companion, HD 80607 (G5V,
V=9.07, B-V=0.87), which is located 21" east.
