The young stellar population in M17 revealed by Chandra
Patrick S. Broos, Eric D. Feigelson, Leisa K. Townsley +5
We report here results from a Chandra ACIS observation of the stellar populations in and around the Messier 17 H II region. The field reveals 886 sources, 771 of which have stellar…
Hard X-rays from Ultra-Compact HII Regions in W49A
M. Tsujimoto, T. Hosokawa, E. D. Feigelson +2
We report the Chandra detection of hard X-ray emission from the Welch ring in W49A, an organized structure of ultra-compact (UC) HII regions containing a dozen nascent early-type s…
Binarity as a key factor in protoplanetary disk evolution: Spitzer disk census of the eta Chamaeleontis cluster
J. Bouwman, W. A. Lawson, C. Dominik +4
The formation of planets is directly linked to the evolution of the circumstellar (CS) disk from which they are born. The dissipation timescales of CS disks are, therefore, of dire…
An X-ray Census of Young Stars in the Massive Southern Star-Forming Complex NGC 6357
Junfeng Wang, Leisa K. Townsley, Eric D. Feigelson +4
We present the first high spatial resolution X-ray study of the massive star forming region NGC 6357, obtained in a 38 ks Chandra/ACIS observation. Inside the brightest constituent…
The XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST)
M. Guedel, K. R. Briggs, K. Arzner +18
(abridged:) The XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST) surveys the most populated ~5 square degrees of the Taurus star formation region, using the XMM-Newt…
A Re-appraisal of the Habitability of Planets Around M Dwarf Stars
Jill C. Tarter, Peter R. Backus, Rocco L. Mancinelli +29
Stable, hydrogen-burning, M dwarf stars comprise about 75% of all stars in the Galaxy. They are extremely long-lived and because they are much smaller in mass than the Sun (between…
