Abstract (from CDS):

A planet transits an 11th magnitude, G1 V star in the constellation Corona Borealis. We designate the planet XO-1b and the star XO-1, also known as GSC 02041-01657. XO-1 lacks a trigonometric distance; we estimate it to be 200±20 pc. Of the 10 stars currently known to host extrasolar transiting planets, the star XO-1 is the most similar to the Sun in its physical characteristics: its radius is 1.0±0.08 R☉, its mass is 1.0±0.03 M☉, its Vsini<3 km/s, and its metallicity [Fe/H] is 0.015±0.04. The orbital period of the planet XO-1b is 3.941534±0.000027 days, one of the longer ones known. The planetary mass is 0.90±0.07MJ, which is marginally larger than that of other transiting planets with periods between 3 and 4 days. Both the planetary radius and the inclination are functions of the spectroscopically determined stellar radius. If the stellar radius is 1.0±0.08 R☉, then the planetary radius is 1.30±0.11RJand the inclination of the orbit is 87°.7±1°.2. We have demonstrated a productive international collaboration between professional and amateur astronomers that was important to distinguishing this planet from many other similar candidates.
