Star Formation in the Orion Nebula I: Stellar Content
August Muench, Konstantin Getman, Lynne Hillenbrand +1
The Orion Nebula is one of the most frequently observed nearby (<1 kiloparsec) star forming regions and, consequently, the subject of a large bibliography of observations and inter…
X-Ray flares in Orion Young Stars. II. Flares, Magnetospheres, and Protoplanetary Disks
Konstantin V. Getman, Eric D. Feigelson, Giuseppina Micela +3
We study the properties of powerful X-ray flares from 161 pre-main sequence (PMS) stars observed with the Chandra X-ray Observatory in the Orion Nebula region. Relationships betwee…
X-ray flares in Orion young stars. I. Flare characteristics
Konstantin V. Getman, Eric D. Feigelson, Patrick S. Broos +2
Pre-main sequence (PMS) stars are known to produce powerful X-ray flares which resemble magnetic reconnection solar flares scaled by factors up to 10^4. However, numerous puzzles a…
A Chandra Study of the Rosette Star-Forming Complex. I. The Stellar Population and Structure of the Young Open Cluster NGC 2244
Junfeng Wang, Leisa K. Townsley, Eric D. Feigelson +4
We present the first high spatial resolution Chandra X-ray study of NGC 2244, the 2 Myr old stellar cluster immersed in the Rosette Nebula. Over 900 X-ray sources are detected; 77%…
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…
