High-spatial resolution U–Pb dating of phosphate minerals in Martian meteorite Allan Hills 84001
U–Pb dating phosphates NanoSIMS Martian meteorites ALH 84001
2017/4/11
Phosphate minerals, which are ubiquitous in terrestrial and extra-terrestrial rocks, are important carriers of trace elements,
including U and Th, which provide chronological information because of t...

We study the properties of chaotic motions in the intra cluster medium using a set of 20 galaxy clusters simulated with large dynamical range, using the Adaptive Mesh Refinement code ENZO (e.g. Norman...
High-spatial-resolution imaging of thermal emission from debris disks
circumstellar matter infrared stars – planetary systems
2010/11/11
We have obtained sub-arcsec mid-IR images of a sample of debris disks within 100 pc. For our sample of nineteen A-type debris disk candidates chosen for their IR excess, we have resolved, for the firs...
Observations of dusty torii and compact disks around evolved stars: the high spatial resolution IR view
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
The recent high angular resolution observations have shown that the transition between a globally symmetrical giant and a source surrounded by a spatially complex environment occurs relatively early, ...
