Resolved imaging of extra-solar planets with future 10-100 km optical interferometric arrays

Characterization of Extra-Solar Planets with Direct-Imaging Techniques

Extra-solar planets with SKA

SKA would have distinct capabilities for studies associated with extra-solar planets, their formation and properties.

Extra-solar planets

Fig, 1: Detection methods for extra-solar planets, The lower extent of the lines indicates, roughly, the detectable masses that are in principle within reach of present measurements (solid lines), and those that might be expected within the next 10-20 years (dashed), The (logarithmic) mass scale is shown at left, The miscellaneous signatures to the upper right are less well quantified in mass t...

Direct imaging of extra-solar planets in star forming regions

Context. Most exoplanet imagers consist of ground-based adaptive optics coronagraphic cameras which are currently limited in contrast, sensitivity and astrometric precision, but advantageously observe in the near-infrared window (1–5 μm). Because of these practical limitations, our current observational aim at detecting and characterizing planets puts heavy constraints on target selection, obse...

Pupil phase apodization for achromatic imaging of extra-solar planets

Direct imaging of extra-solar planets in the visible and infrared region has generated great interest among scientists and the general public as well. However, this is a challenging problem. Difficulties of detecting a planet (faint source) are caused, mostly, by two factors: sidelobes caused by starlight diffraction from the edge of the pupil and the randomly scattered starlight caused by the ...
