TL;DR: The Second Workshop on Extreme Precision Radial Velocities defined circa 2015 the state of the art Doppler precision and identified the critical path challenges for reaching 10 cm s−1 measurement precision as mentioned in this paper.
Journal ArticleDOI
Soap 2.0: a tool to estimate the photometric and radial velocity variations induced by stellar spots and plages*
TL;DR: In this article, a new version of the Spot Oscillation And Planet (SOAP) code is proposed to estimate the photometric and radial velocity (RV) variations induced by active regions.

TL;DR: The planet Kepler-78b was discovered and found to have a radius of only 1.16, and the mass of this planet is 1.86 Earth masses, which implies a composition of iron and rock similar to that of the Earth.
