Astronomy: September 2014


We propose a method to distinguish between cloudy, hazy and clearsky (free of clouds and hazes) exoplanet atmospheres that could be applicable to upcoming large aperture space and ground-based telescopes such as JWST and E-ELT.

Future radial velocity, astrometric and direct imaging surveys will find nearby Earth-sized planets within the habitable zone (HZ) in the near future. How can we search for water and oxygen in those non-transiting planets?

In no other field of astrophysics has the impact of new instrumentation been as substantial as in the domain of exoplanets.

ExoEarth yield is a critical science metric for future exoplanet imaging missions. Here we estimate exoEarth candidate yield using single visit completeness for a variety of mission design and astrophysical parameters.
