XO-4b: An Extrasolar Planet Transiting an F5V Star
P. R. McCullough, Christopher J. Burke, Jeff A. Valenti +11
We report the discovery of the planet XO-4b, which transits the star XO-4 (GSC 03793-01994, V=10.7, F5V). Transits are 1.0% deep and 4.4 hours in duration. The star XO-4 has a mass…
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…
Detecting "Temperate" Jupiters: The Prospects of Searching for Transiting Gas Giants in Habitability Zones
S. W. Fleming, S. R. Kane, P. R. McCullough +1
This paper investigates the effects of observing windows on detecting transiting planets by calculating the fraction of planets with a given period that have zero, one (single), tw…
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 +…
The Life Cycle of an XO Planet and the Potential to Detect Transiting Planets of M Dwarfs
Peter R. McCullough, Christopher J. Burke
We describe strategies and tactics for detecting transiting planets, as learned from the experience of the XO Project. A key component is the web-enabled collaboration with a longi…
Observations of Extrasolar Planets Enabled by a Return to the Moon
P. R. McCullough
Ambitious studies of Earth-like extrasolar planets are outlined in the context of an exploration initiative for a return to the Earth's Moon. Two mechanism for linearly polarizing…
