TL;DR: In this article, the smallest radius transiting extrasolar planet (TEP) discovered from the ground, and the first hot Neptune discovered to date by transit searches, was reported.
Journal ArticleDOI
Precision radial velocities with an iodine absorption cell
Geoffrey W. Marcy,R. P. Butler +1 more
TL;DR: In this paper, the authors used gaseous iodine for generating reference absorption lines in stellar spectra taken at high resolution, which provided both a highly precise wavelength scale (calibrated with a Fourier transform spectrum) and a specification of the spectrograph PSF over the entire echelle format.

TL;DR: The detection of Kepler-47 establishes that close binary stars can host complete planetary systems, and reveals two small planets orbiting a pair of two low-mass stars.
