Prior to the arrival of the Cassini-Huygens spacecraft, aerosol production in Titan's
atmosphere was believed to begin in the stratosphere where chemical processes are …

ABSTRACT CO 2 ice is an important reservoir of carbon and oxygen in star-and planet-
forming regions. Together with water and CO, CO 2 sets the physical and chemical …

Nitrous oxide (N2O) is widely used in radiation-chemistry and photochemistry as a
scavenger to convert a hydrated electron (e aq–) into a hydroxyl radical (· OH). However, few …

Low-temperature microwave-powered plasma based on hydrogen and hydrogen with noble
gas mixtures are widely used as a continuous vacuum ultraviolet (VUV) source in laboratory …

ABSTRACT CO 2 is one of the most abundant components of ices in the interstellar medium;
however, its formation mechanism has not been clearly identified. Here we report an …

The photodesorption of CO 2 from CO 2 (ice) at 75 K when irradiated by Lyman-α light is
strongly mediated by vibrational relaxation of highly vibrationally excited molecules …

In order to simulate the interaction of sunlight with planetary atmospheres, including Pluto,
Titan and the early Earth, many laboratory studies have used high-power broadband lamps …

As a model for silicate dust grains in the interstellar medium, we have used high area
amorphous SiO 2 as a surface on which to carry out Lyman-α (10.2 eV) photodecomposition …

The photochemical decomposition of CO 2 (ice) at 75 K by Lyman-α radiation (10.2 eV) has
been studied using transmission infrared spectroscopy. An isotope effect in the …

Formation of organic aerosols driven by photochemical reactions has been observed and
suggested in CH 4-containing atmospheres, including Titan and early Earth. However, the …
