Robo-AO and SOAR High-Resolution Surveys of Exoplanet Hosting Stars
Frontiers in Astronomy and Space Sciences, 2021 In the past decade, space-based transit surveys have delivered thousands of potential planet-hosting systems. Each of these needs to be vetted and characterized using follow-up high-resolution imaging.

Exoplanets - search methods, discoveries, and prospects for astrobiology [PDF]
, 2008 Whereas the Solar System has Mars and Europa as the best candidates for finding fossil/extant life as we know it - based on complex carbon compounds and liquid water - the 263 (non-pulsar) planetary systems around other stars as known at 15 September ...

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012 Exoplanets—planets orbiting around stars other than our own Sun—appear to be common. Significant research effort is now focused on the observation and characterization of exoplanet atmospheres. Species such as water vapour, methane, carbon monoxide and carbon dioxide have been observed in a handful of hot, giant, gaseous planets, but ...

Exoplanet albedo spectra and colors as a function of planet phase, separation, and metallicity [PDF]
, 2010 First generation optical coronagraphic telescopes will obtain images of cool gas and ice giant exoplanets around nearby stars. The albedo spectra of exoplanets at planet-star separations larger than about 1 AU are dominated by reflected light to beyond 1

The Detection and Characterization of Extrasolar Planets
Challenges, 2014 We have now confirmed the existence of > 1800 planets orbiting stars other thanthe Sun; known as extrasolar planets or exoplanets. The different methods for detectingsuch planets are sensitive to different regions of parameter space, and so, we are ...

Habitable Zones in Binary Star Systems: A Zoology
Galaxies, 2020 Several concepts have been brought forward to determine where terrestrial planets are likely to remain habitable in multi-stellar environments. Isophote-based habitable zones, for instance, rely on insolation geometry to predict habitability, whereas ...

Adaptive Optics Observations of Exoplanets, Brown Dwarfs, & Binary Stars [PDF]
, 2011 The current direct observations of brown dwarfs and exoplanets have been obtained using instruments not specifically designed for overcoming the large contrast ratio between the host star and any wide-separation faint companions. However, we are about to
