The discovery of the first extra-solar planet surrounding a main-sequence star was
announced in 1995, based on very precise radial velocity (Doppler) measurements. A total …

▪ Abstract The field of optical and infrared (IR) interferometry has seen rapid technical and
scientific progress over the past few years. A number of instruments capable of precise …

This paper presents a model for the outcome of collisions between planetesimals in a debris
disc, and assesses the impact of collisional processes on the structure and size distribution …

We present a concept dedicated to the detection of faint companions or other morphological
components in the neighbouring of a star by means of coronagraphy. Basically this method …

The discovery of extrasolar planets is one of the greatest achievements of modern
astronomy. The detection of planets that vary widely in mass demonstrates that extrasolar …

Future spaceborne interferometric arrays must meet stringent optical performance and
tolerance requirements while exhibiting modularity and acceptable manufacture and …

This paper provides a derivation from first principles of the stringent symmetry and stability
requirements which deep stellar nulling demands, and also includes a brief status report on …

Radiation theory and measurements are at the core of the climate change debate. This new
book describes in detail the basic physics used in the radiative transfer codes that are a key …

In the area of long-baseline nulling interferometry, high rejection ratios are needed to cancel
out the light of a bright central source and look for nearby faint structures or companions …

We present a catalog of 38 young solar analogs within 25 pc, stars that are uniquely well
suited for observations of their circumstellar environments to improve our understanding of …
