Abstract:
We present photometry of HD 189733 during eight transits of its
close-in giant planet, and out-of-transit photometry spanning 2yr.
Using the transit photometry, we determine the stellar and planetary
radii and the photometric ephemeris. Outside of transits, there are
quasi-periodic flux variations with a 13.4-day period that we
attribute to stellar rotation. In combination with previous results,
we derive upper limits on the orbital eccentricity and on the true
angle between the stellar rotation axis and planetary orbit (as
opposed to the angle between the projections of those axes on the
sky).
Description:
Our observations took place in 2005 and 2006 using telescopes at four
different observatories.
We observed the transits of UT 2006 July 21 and September 10 with the
1.2m telescope at the Fred L. Whipple Observatory (FLWO) on Mount
Hopkins, Arizona.
We used the T10 0.8m automated photometric telescope (APT) at Fairborn
Observatory, in Arizona, to observe four complete transits of HD
189733b and to monitor the out-of-transit stellar flux. We observed
the transits of UT 2005 November 28, 2006 May 2, 2006 May 22, and 2006
June 11.
We observed the transit of UT 2006 August 21 with the 2m telescope at
the Multicolor Active Galactic Nuclei Monitoring (MAGNUM) observatory
on Haleakala, Hawaii.
We observed the transit of 2006 September 5 with the 1m telescope at
Wise Observatory, in Israel.
