Reaction models in nuclear astrophysics

open access: yesEPJ Web of Conferences, 2016
We present different reaction models commonly used in nuclear astrophysics, in particular for the nucleosynthesis of light elements. Pioneering works were performed within the potential model, where the internal structure of the colliding nuclei is ...

State of the Field: Scientific Internationalism during the Cold War

open access: yesHistory, EarlyView.
ABSTRACT This article offers a state‐of‐the‐field assessment of the historiography of scientific internationalism during the Cold War, focusing on three connected problems: the reconceptualization of science diplomacy, the emergence of ‘techno‐dissent’ and the ethical turn in the history of science and technology.

Design Considerations for Visualization Transitions of 3D Spatial Data in Hybrid AR‐Desktop Environments

open access: yesComputer Graphics Forum, EarlyView.
We present design considerations for animated transitions of the appearance of 3D spatial datasets in a hybrid Augmented Reality‐desktop context. Such hybrid interfaces combine both traditional and immersive displays to facilitate the exploration of 2D and 3D data representations in the environment in which they are best displayed.

Nuclear astrophysics with radioactive beams [PDF]

open access: yesPhysics Reports, 2010
The quest to comprehend how nuclear processes influence astrophysical phenomena is driving experimental and theoretical research programs worldwide. One of the main goals in nuclear astrophysics is to understand how energy is generated in stars, how elements are synthesized in stellar events and what the nature of neutron stars is.

Xenoliths in meteorites: Insights into the dynamics of material exchange between asteroids

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract A minor fraction of meteorites contains xenoliths, that is, clasts that were formed on a different parent body than that of the host lithology. The occurrence of xenoliths is direct evidence for the exchange of material between asteroids, including exchanges between asteroids from the carbonaceous (CC) and non‐carbonaceous (NC) reservoirs ...

A Microkrystite from the Australasian Tektite/Microtektite Strewn Field

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Microkrystites are glassy impact spherules. They contain primary crystallites carrying information on the physical and chemical conditions prevailing during vaporization, melting, and ejection in large impact cratering events. We report on the geochemistry and mineralogy down to nanometer scale of the first microkrystite (ODP1144A,14) from the
