Underground nuclear astrophysics studies with CASPAR

EPJ Web of Conferences, 2016
The drive of low-energy nuclear astrophysics laboratories is to study the reactions of importance to stellar burning processes and elemental production through stellar nucleosynthesis, over the energy range of astrophysical interest.

Using Visual Analytics to Maintain Situation Awareness in Astrophysics [PDF]

, 2008
We present a novel collaborative visual analytics application for cognitively overloaded users in the astrophysics domain. The system was developed for scientists needing to analyze heterogeneous, complex data under time pressure, and then make ...

Magnetic properties of geraisites, the first tektite strewn field identified in Brazil

Meteoritics &Planetary Science, EarlyView.
Abstract Geraisites are a newly recognized class of tektite from Brazil. They occur as centimeter‐sized, elongated to subspherical bodies scattered across surface gravel and shallow subsurface layers within a ~90‐km‐long strewn field extending between the municipalities of São João do Paraíso and Curral de Dentro, near the border between the states of ...

Astrophysics experiments with radioactive beams at ATLAS

AIP Advances, 2014
Reactions involving short-lived nuclei play an important role in nuclear astrophysics, especially in explosive scenarios which occur in novae, supernovae or X-ray bursts.

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.

Impact‐diagnostic criteria for use in confirming a meteorite impact origin of terrestrial geological structures: Recommendations by the Impact Cratering Committee of the Meteoritical Society

Meteoritics &Planetary Science, EarlyView.
Abstract The framework of the Impact Cratering Committee (ICC) of the Meteoritical Society was approved in 2020, with the first committee members appointed in 2023. The ICC has a mandate to (1) approve, maintain, and update a database of confirmed terrestrial meteorite impact structures, (2) define and regularly update the criteria used for ...

Reassessing the organic carbon budget in the Murchison meteorite through an extraction–recovery mass‐balance approach

Meteoritics &Planetary Science, EarlyView.
Abstract A substantial fraction of organic carbon in carbonaceous chondrites has long been described as “missing,” reflecting incomplete recovery and limited resolution of operationally defined organic components. Here, we present a quantitative reassessment of the carbon budget in the Murchison meteorite using an integrated extraction–recovery mass ...

Connecting astrophysics to laboratory fluid dynamics - Astrophysical thermonuclear flashes

30th Fluid Dynamics Conference, 1999
We discuss the strategy followed by the Center for Astrophysical Thermonuclear Flashes in validating codes designed for thermonuclear burning on the surfaces or the interior of evolved compact stars. As an illustration, we discuss in some detail our progress in simulating Rayleigh-Taylor mixing relevant to Type la supernovae. © 1999 by The Univ.
