First Results from the PAMELA Space Mission
M. Boezio, V. Bonvicini, G. Jerse +53
On the 15th of June 2006, the PAMELA satellite-borne experiment was launched from the Baikonur cosmodrome and it has been collecting data since July 2006. The apparatus comprises a…
A new measurement of the antiproton-to-proton flux ratio up to 100 GeV in the cosmic radiation
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +50
A new measurement of the cosmic ray antiproton-to-proton flux ratio between 1 and 100 GeV is presented. The results were obtained with the PAMELA experiment, which was launched int…
Evidence for CO depletion in the inner regions of gas-rich protoplanetary disks
G. van der Plas, M. E. van den Ancker, B. Acke +4
We investigate the physical properties and spatial distribution of Carbon Monoxide (CO) gas in the disks around the Herbig Ae/Be stars HD 97048 and HD 100546. Using high-spectral-r…
The structure of the protoplanetary disk surrounding three young intermediate mass stars. II. Spatially resolved dust and gas distribution
D. Fedele, M. E. van den Ancker, B. Acke +7
[Abridged] We present the first direct comparison of the distribution of the gas, as traced by the [OI] 6300 AA emission, and the dust, as traced by the 10 micron emission, in the…
The Structure of Protoplanetary Disks Surrounding Three Young Intermediate Mass Stars. I. Resolving the disk rotation in the [OI] 6300 Åline
G. van der Plas, M. E. van den Ancker, D. Fedele +4
We present high spectral resolution optical spectra of three young intermediate mass stars, in all of which we spectrally resolve the 6300 Angstrom [OI] emission line. Two of these…
A Search for NIR Molecular Hydrogen Emission in the CTTS LkHa 264 and the debris disk 49 Cet
A. Carmona, M. E van den Ancker, Th. Henning +3
We report on the first results of a search for H2 emission from protoplanetary disks using CRIRES, ESO's new VLT high resolution NIR spectrograph. We observed the CTTS LkHa 264 and…
