Abstract:
We monitored three transits of the giant gas planet around the nearby
K dwarf HD 189733 with the ACS camera on the Hubble Space Telescope.
The resulting very-high accuracy light-curve (signal-to-noise ratio
near 15000 on individual measurements, 35000 on 10-min averages)
allows a direct geometric measurement of the orbital inclination,
radius ratio and scale of the system: i=85.68±0.04,
Rpl/R*=0.1572±0.0004, a/R*=8.92±0.09.
