TL;DR: In this article, the signatures of molecular ions that can be found in upper atmospheres above cloud decks were used to distinguish super-Earths with a thin atmosphere from H2-dominated sub-Neptunes to address the critical question of whether a low gravity planet around a low mass active star is able to retain its volatile components.

TL;DR: In this paper, a room-temperature dusty plasma experiment was used to detect nitrogen and oxygen atoms in Pluto aerosol analogues, and the results showed that the molecules constituting samples P400 and P600 are very rich in nitrogen atoms (up to 45% in mass of N elements).

TL;DR: In this article, a new set of optical constants for Pluto tholins were derived from a set of Titan aerosol analogues (tholins) using spectroscopic ellipsometry.

TL;DR: In this article, the signatures of molecular ions that can be found in upper atmospheres above cloud decks were used to detect super-Earths with a thin atmosphere from H$_2$-dominated sub-Neptunes.

TL;DR: In this paper, a series of positive ion measurements were performed in three CH4 mixing ratios (1, 5% and 10%) showing a variability in ion population, which is consistent with modeling work simulating aerosol growth in Titan's ionosphere, which includes mass exchange primarily between HCNH+ and C2H5+ and negatively charged particles.
