Circumstellar Disks in the Outer Galaxy: the Star-Forming Region NGC 1893
M. Caramazza, G. Micela, L. Prisinzano +3
It is still debated whether star formation process depends on environment. In particular it is yet unclear whether star formation in the outer Galaxy, where the environmental condi…
Spitzer-MIPS Observations of the eta Cha Young Association
Thomas. N. Gautier, L. M. Rebull, K. R. Stapelfeldt +1
We have mapped the eta Chamaeleontis young stellar association in the far-infrared with the Multiband Imaging Photometer for Spitzer (MIPS) on the Spitzer Space Telescope. All sixt…
Spitzer/MIPS Observations of Stars in the Beta Pictoris Moving Group
L. M. Rebull, K. R. Stapelfeldt, M. W. Werner +7
We present Multiband Imaging Photometer for Spitzer (MIPS) observations at 24 and 70 microns for 30 stars, and at 160 microns for a subset of 12 stars, in the nearby (~30 pc), youn…
X-ray properties of protostars in the Orion Nebula
L. Prisinzano, G. Micela, E. Flaccomio +8
The origin and evolution of the X-rays in very young stellar objects (YSOs) are not yet well understood since it is very hard to observe YSOs in the protostellar phase. We study th…
Million-Degree Plasma Pervading the Extended Orion Nebula
M. Guedel, K. R. Briggs, T. Montmerle +3
Most stars form as members of large associations within dense, very cold (10-100 K) molecular clouds. The nearby giant molecular cloud in Orion hosts several thousand stars of ages…
Accretion and Outflow-Related X-Rays in T Tauri Stars
M. Guedel, K. Briggs, K. Arzner +22
We report on accretion- and outflow-related X-rays from T Tauri stars, based on results from the "XMM-Newton Extended Survey of the Taurus Molecular Cloud." X-rays potentially form…
