Abstract:
We present the discovery of WASP-39b, a highly inflated transiting
Saturn-mass planet orbiting a late G-type dwarf star with a period of
4.055259-days, Transit Epoch 2455342.9688±0.0002 (HJD), of duration
0.1168d.
Description:
We report the discovery WASP-39b a highly inflated transiting
extrasolar planet. We performed a simultaneous fit to transit
photometry and radial velocity measurements and obtained a planetary
density of 0.141±0.02rhoJ (where rhoJ is the density of
Jupiter). Thus, WASP-39b is the third least dense planet identified by
a ground-based transit survey.
