Abstract:
We present photometry of the G0 star HAT-P-1 during six transits of
its close-in giant planet, and we refine the estimates of the system
parameters. Relative to Jupiter's properties, HAT-P-1b is 1.20±0.05
times larger, and its surface gravity is 2.7±0.2 times weaker.
Although it remains the case that HAT-P-1b is among the least dense of
the known sample of transiting exoplanets, its properties are in
accord with previously published models of strongly irradiated,
coreless, solar-composition giant planets. The times of the transits
have a typical accuracy of 1 minute and do not depart significantly
from a constant period.
Description:
Our observations took place in late 2006, using telescopes at three
different observatories. We observed six distinct transits and
produced seven independent light curves. We observed the transits of
UT 2006 September 18, September 27, and October 6 with the 1.2m
telescope at the Fred L. Whipple Observatory (FLWO) on Mount Hopkins,
Arizona. We observed the transits of UT 2006 September 1, September
10, and September 18 using the Nickel 1m telescope at Lick Observatory
on Mount Hamilton, California. We observed the transits of UT 2006
September 14, November 20, and November 29 using the 1m telescope at
Wise Observatory in Israel.
