Transport of dust across the Solar System: Constraints on the spatial origin of individual micrometeorites from cosmic-ray exposure
Reto Georg Trappitsch, Xuan Li
The origin of micrometeorites (MMs) from asteroids and comets is well-established, but the relative contribution from these two classes remains poorly resolved. Likewise, determining the precise origin of individual MMs is an open challenge. Here, cosmic-r ...
Royal Soc2024Shape Models of Lucy Targets (3548) Eurybates and (21900) Orus from Disk-integrated Photometry
We use our new light curves, along with historical data, to determine the rotation state, photometric properties, and convex shape models of the targets of the Lucy mission (3548) Eurybates and (21900) Orus. We determine a retrograde spin for both targets, ...
IOP Publishing Ltd2023Disappearance of the extended main sequence turn-off in intermediate age clusters as a consequence of magnetic braking
Context. Extended main sequence turn-offs are features commonly found in the colour-magnitude diagrams of young and intermediate age (less than about 2 Gyr) massive star clusters, where the main sequence turn-off is broader than can be explained by photome ...
EDP SCIENCES S A2019Mass-Spectrometric Detection of Low-Ppm Contaminants in Sputter Process Systems at 10-2 Mbar, Using a Directly Exposed Ion-Source
Trace contaminants in sputter atmospheres (10(-2) mbar Ar) are determined with a mass spectrometer whose ionizer is directly exposed to the process pressure, whereas the quadrupole filter is kept at high vacuum. The background limitations inherent to conve ...
