Astrophysical ices are being exposed to ionizing radiation in space environments, which
trigger new reactions and desorption processes. In the lab, such processing by radiation has …

Chemical reactions and desorption processes are being triggered by incoming ionizing
radiation over astrophysical ices in cold space environments. The quantification of these …

The chemical inventory of protoplanetary midplanes is the basis for forming planetesimals.
Among them, solid-state reactions based on CO/CO 2 toward molecular complexity on …

In this work, we focus on the study of radiation-induced desorption processes that occurred
in acetonitrile ice irradiated by broad-band X-rays (6 eV to 2 keV) monitored by Fourier …

We investigate the effects produced mainly by broadband soft X-rays up to 2 keV (plus fast
(∼ keV) photoelectrons and low-energy (∼ eV) induced secondary electrons) in the ice …

In this combined experimental–theoretical work we focus on the physical and chemical
changes induced by soft X-rays on sulfur dioxide (SO2) ice at a very low temperature, in an …

In this study, we employed broad-band X-rays (6–2000 eV) to irradiate the frozen acetone
CH3COCH3, at the temperature of 12 K, with different photon fluences up to 2.7× 1018 …

We report theoretically calculated equilibrium oxygen isotopic fractionation factors (17 O/16
O, 18 O/16 O) between a set of representative O-bearing organic molecules and water, as …

Cubic ice (ice Ic) is a crystalline phase of solid water, which exists in the earth's atmosphere
and extraterrestrial environments. We provide experimental evidence that dissociation of …

We present research that systematically examines acetone interacting with various D2O ices
of terrestrial and astrophysical interest using time-resolved, in situ reflection absorption …
