Abstract 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 …

Exoplanets can be detected with various observational techniques. Among them, radial
velocity (RV) has the key advantages of revealing the architecture of planetary systems and …

Context. ESPRESSO is the new high-resolution spectrograph of ESO's Very Large
Telescope (VLT). It was designed for ultra-high radial-velocity (RV) precision and extreme …

Abstract NASA's Kepler Space Telescope was designed to determine the frequency of Earth-
sized planets orbiting Sun-like stars, but these planets are on the very edge of the mission's …

Context. The High Accuracy Radial velocity Planet Searcher (HARPS) spectrograph has
been mounted since 2003 at the ESO 3.6 m telescope in La Silla and provides state-of-the …

Context. Searching for planets around stars with different masses helps us to assess the
outcome of planetary formation for different initial conditions. The low-mass M dwarfs are …

We report on the orbital architectures of Kepler systems having multiple-planet candidates
identified in the analysis of data from the first six quarters of Kepler data and reported by …

About one-third of the∼ 1200 transiting planet candidates detected in the first four months of
Kepler data are members of multiple candidate systems. There are 115 target stars with two …

We present a novel, model-independent framework for studying the architecture of an
exoplanetary system at the system level. This framework allows us to characterise, quantify …

Exoplanets down to the size of Earth have been found, but not in the habitable zone—that is,
at a distance from the parent star at which water, if present, would be liquid. There are …
