The Transit Light Curve Project. IX. Evidence for a Smaller Radius of the Exoplanet XO-3b
Joshua N. Winn, Matthew J. Holman, Guillermo Torres +9
We present photometry of 13 transits of XO-3b, a massive transiting planet on an eccentric orbit. Previous data led to two inconsistent estimates of the planetary radius. Our data…
XO-3b: A Massive Planet in an Eccentric Orbit Transiting an F5V Star
Christopher M. Johns-Krull, Peter R. McCullough, Christopher J. Burke +13
We report the discovery of a massive (Mpsini = 13.02 +/- 0.64 Mjup; total mass 13.25 +/- 0.64 Mjup), large (1.95 +/- 0.16 Rjup) planet in a transiting, eccentric orbit (e = 0.260 +…
XO-2b: Transiting Hot Jupiter in a Metal-rich Common Proper Motion Binary
Christopher J. Burke, P. R. McCullough, Jeff A. Valenti +15
We report on a V=11.2 early K dwarf, XO-2 (GSC 03413-00005), that hosts a Rp=0.98+0.03/-0.01 Rjup, Mp=0.57+/-0.06 Mjup transiting extrasolar planet, XO-2b, with an orbital period o…
