Monitoring the Planetary Transits of HD 209458b
Abstract
Portions of four planetary transits of HD 209458 were observed using the Fine Guidance Sensors (FGS) onboard the Hubble Space Telescope (HST). The combined data were fit with a transit model, yielding a determination of the stellar radius R* = 1.17 ± 0.03 R⊙, the planetary radius Rp = 1.43 ± 0.04 RJ, and the orbital inclination i = 86.1o ± 0.1o.
