NASA’S Spitzer Marks Beginning of New Age of Planetary Science

“In the new studies, Spitzer has directly observed the warm infrared glows of two previously detected “hot Jupiter” planets, designated HD 209458b and TrES-1. Hot Jupiters are extrasolar gas giants that zip closely around their parent stars.”

TrES-1: The Transiting Planet of a Bright K0V Star, arXiv.org e-Print archive

“We report the detection of a transiting Jupiter-sized planet orbiting a relatively bright (V=11.79) K0V star. We designate the planet TrES-1; its inferred mass is 0.75 +/- 0.07 Jupiter masses, its radius is 1.08 (+0.18/-0.04) Jupiter radii, and its orbital period is 3.030065 +/- 0.000008 days.”
