Close-Orbiting Exoplanets: Formation, Migration Mechanisms and Properties [PDF]

open access: possible, 2008
The discovery of a signal from a putative extra-solar planet around the nearby Sun-like star 51 Peg by Mayor & Queloz and the rapid confirmation by Marcy & Butler was the main starting point for the field of extrasolar planets. More than a decade later, ‘51 Peg - type planets’ or ‘hot Jupiters’ are frequently discovered and characterised by a variety ...

Precision formation flying at megameter separations for exoplanet characterization

Acta Astronautica, 2016
Abstract Starshade missions offer a near-term capability to measure the spectra of Earth-sized exoplanets, searching for possible bio-indicators. To function, a starshade and telescope separated by approximately 50 Mm must align to the meter-level on the line to the target star.
