Population and dynamical state of the eta Chamaeleontis sparse young open cluster
A-Ran Lyo, Warrick A. Lawson, Eric D. Feigelson +1
We report new results in our continuing study of the unique compact (1 pc extent), nearby (d = 97 pc), young (t = 9 Myr) stellar cluster dominated by the B9 star eta Chamaeleontis.…
The epsilon Chamaeleontis young stellar group and the characterization of sparse stellar clusters
Eric D. Feigelson, Warrick A. Lawson, Gordon P. Garmire
We present the outcomes of a Chandra X-ray Observatory snapshot study of five nearby Herbig Ae/Be (HAeBe) stars which are kinematically linked with the Oph-Sco-Cen Association (OSC…
Determination of the gas-to-dust ratio in nearby dense clouds using X-ray absorption measurements
MyHa Vuong, Thierry Montmerle, Nicolas Grosso +3
We present a comparison of the gas and dust properties of the dense interstellar matter in six nearby star-forming regions (d<500 pc): rho Oph, Cha I, R CrA, IC 348, NGC 1333, and…
Ten Million Degree Gas in M 17 and the Rosette Nebula: X-ray Flows in Galactic H II Regions
L. K. Townsley, E. D. Feigelson, T. Montmerle +3
We present the first high-spatial-resolution X-ray images of two high-mass star forming regions, the Omega Nebula (M 17) and the Rosette Nebula (NGC 2237--2246), obtained with the…
Coronal X-ray emission from an intermediate-age brown dwarf
Yohko Tsuboi, Yoshitomo Maeda, Eric D. Feigelson +4
We report the X-ray detection of the brown dwarf (BD) companion TWA 5B in a Myr old pre-main sequence binary system. We clearly resolve the faint companion (35 photons)…
A Deep Chandra Catalog of X-ray Point Sources toward the Galactic Center
M. P. Muno, F. K. Baganoff, M. W. Bautz +7
(abridged) We present a catalog of 2357 point sources detected during 590 ks of Chandra observations of the 17-by-17 arcminute field around Sgr A*. This field encompasses a physica…
