Formation of CO2 Driven by Photochemistry of Water Ice Mixed with Carbon Grains
The Astrophysical Journal, 2023 We present results on photochemistry of carbon-grains/water-ice mixtures at temperatures from 10 to 150 K. Such a temperature range corresponds to the physical conditions found in molecular clouds, hot cores and corinos, protostellar envelopes, and ...

Double to Tenfold M-shell Photoionization of Singly Charged Lanthanum Ions
The Astrophysical JournalUsing the photon-ion merged-beams technique at the PETRA III synchrotron light source, we have measured cross sections for double and up to tenfold photoionization of La ^+ ions by a single photon in the energy range 820–1400 eV, where resonances and ...

Detectors and Shieldings: Past and Future at LUNA
UniverseNuclear reactions are responsible for the chemical evolution of stars, galaxies and the Universe. Unfortunately, at temperatures of interest for nuclear astrophysics, the cross-sections of the thermonuclear reactions are in the pico- femto-barn range and

ISO and Laboratory Astrophysics [PDF]
Symposium - International Astronomical Union, 1992 ISO, the Infrared Space Observatory is capable of measuring spectra across most of the mid-infrared, the region from 4000 to 500 cm−1 (2.5-20 μm). Of these 3500 cm−1, about 670 have been inaccessible to astronomers due to strong atmospheric absorptions and about 750 cm−1 require an airborne platform, making access limited. ISO will provide high quality

Advances in instrumentation for nuclear astrophysics
AIP Advances, 2014 The study of the nuclear physics properties which govern energy generation and nucleosynthesis in the astrophysical phenomena we observe in the universe is crucial to understanding how these objects behave and how the chemical history of the universe ...
