How to distinguish between cloudy mini-Neptunes and water/volatile-dominated super-Earths
B Benneke, S Seager - The Astrophysical Journal, 2013 - iopscience.iop.org
One of the most profound questions about the newly discovered class of low-density super-
Earths is whether these exoplanets are predominately H 2-dominated mini-Neptunes or …

The hazy and metal-rich atmosphere of GJ 1214 b constrained by near-and mid-infrared transmission spectroscopy
The near-infrared transmission spectrum of the warm sub-Neptune exoplanet GJ 1214 b has
been observed to be flat and featureless, implying a high metallicity atmosphere with …

Ground-based near-UV observations of 15 transiting exoplanets: constraints on their atmospheres and no evidence for asymmetrical transits
Transits of exoplanets observed in the near-UV have been used to study the scattering
properties of their atmospheres and possible star–planet interactions. We observed the …
