TL;DR: In this article, the authors present an analysis of the CoRoT-7b radial velocity measurements that uses very few and simple assumptions in treating the activity signal, and demonstrate that the contribution of activity to the final radial velocity curve is negligible and that the K-amplitude due to the planet is well constrained.

TL;DR: It is discussed how to read a planet's spectrum to assess its habitability and search for the signatures of a biosphere and an amazing scope of diverse planets that will set planet formation, evolution, and the authors' planet into an overall context.

TL;DR: The Nearby Earth Astrometric Telescope (NEAT) as discussed by the authors is designed to carry out space-borne extremely high-precision measurements at the 0.05 mu as (1 sigma) accuracy level, sufficient to detect dynamical effects due to orbiting planets of mass even lower than Earth's around the nearest stars.

TL;DR: In this paper, the authors proposed a mission called Darwin, whose primary goal is the study of terrestrial extrasolar planets and the search for life on them, and described different characteristics of the instrument.

TL;DR: The evolution of Earth-like habitable planets is a complex process that depends on the geodynamical and geophysical environments, and it is necessary that plate tectonics remain active over billions of years.
