Properties of transiting extrasolar planets [PDF]

, 2011
A growing number of extrasolar planets have been detected using transit photometry, and these systems are presently important, in that these planets have strongly constrained parameters, particularly their radii, and this combined with the masses can ...

Helium Depletion in Escaping Atmospheres of Sub-Neptunes: A Signature of Primary-to-secondary Transition

The Astrophysical Journal
Short-period sub-Neptunes are common in extrasolar systems. These sub-Neptunes are generally thought to have primary atmospheres of protoplanetary-disk gas origin.

Direct imaging of massive extrasolar planets

, 2010
The direct detection of an extrasolar planet can provide accurate measurements of its orbit, mass and composition, greatly improving our understanding of how planets form and evolve. Recent advances in ground-based and space-based imaging techniques have

Carbon Cycle Imbalances on Arid Terrestrial Planets with Implications for Venus

The Planetary Science Journal
Arid terrestrial exoplanets are potentially abundant and are thus interesting targets in the search for life. In particular, M-dwarf planets such as those in the TRAPPIST-1 system may possess limited surface water, whereas early solar system terrestrials

The Exozodi Spectral Effect: Residual Habitable Zone Dust May Bias exoEarth Characterization

The Astronomical Journal
All exoplanetary systems are expected to host exozodiacal dust, or exozodi, originating from planetesimals. For many stars, exozodi will likely be the largest source of astrophysical noise in direct observations of terrestrial exoplanets. Nearby Sun-like

Role of Magma Oceans in Controlling Carbon and Oxygen of Sub-Neptune Atmospheres

The Astrophysical Journal
Most exoplanets with a few Earth radii are more inflated than bare-rock planets with the same mass, indicating a substantial volatile amount. Neither the origin of the volatiles nor the planet’s bulk composition can be constrained from the mass–radius ...
