Extragalactic eclipsing binaries: astrophysical laboratories [PDF]

New Astronomy Reviews, 2004
Eclipsing binaries (EBs) have long been known for providing accurate stellar fundamental properties, such as masses and radii. These are obtained from the modeling of light and radial velocity curves and, with input data of good quality, uncertainties of a few percent in the components’ physical properties are now routinely achieved.

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 ...

Laboratory for Underground Nuclear Astrophysics (LUNA)

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1994
A compact high-current 50 kV ion accelerator facility including a windowless gas target system, a beam calorimeter, and detector telescopes in close geometry has been built and tested. The data acquisition and analysis involved a multiparameter system and a Monte Carlo program.

Recent Results on Neutrino Masses [PDF]

, 1997
I review the main options one has of introducing mass to neutrinos, including broken R-parity models, as well as the constraints on neutrino properties that follow from astrophysics, cosmology as well as laboratory observations.Comment: 13 pages.

Felsenkeller shallow-underground accelerator laboratory for nuclear astrophysics

EPJ Web of Conferences, 2015
Favored by the low background in underground laboratories, low-background accelerator-based experiments are an important tool to study nuclear reactions involving stable charged particles. This technique has been used for many years with great success at
