Einstein IPC observations of the nearby Chamaeleon I star forming cloud show 22 well-resolved soft X-ray sources in a 1x2 deg region. Twelve are associated with H-alpha emission line pre-main sequence (PMS) stars, and four with optically selected PMS stars. Several X-ray sources have two or more PMS stars in their error circles. Optical spectra were obtained at CTIO of possible stellar counterparts of the remaining X-ray sources. They reveal 5 probable new cloud members, K7-MO stars with weak…

An X-Ray Census of Young Stars in the Chamaeleon I North Cloud
Sensitive X-ray imaging surveys provide a new and effective tool to establish the census of pre-main-sequence (PMS) stars in nearby young stellar clusters. We report here a deep Chandra X-Ray
A deep XMM-Newton X-ray observation of the Chamaeleon I dark cloud
Context. Low-mass stars are known to exhibit strong X-ray emission during the early stages of evolution. Nearby star forming regions are ideal targets to study the X-ray properties of pre-main
The X-Ray Emission of T Tauri Stars in Taurus-Auriga as Seen from the Einstein Observatory IPC
We present a systematic study of the X-ray emission of pre-main-sequence stars in the Taurus-Auriga cluster. The sample consists of the 69 catalogued stars in this region observed with the Einstein
ROSAT X-ray detection of a young brown dwarf in the chamaeleon I dark cloud
Photometry and spectroscopy of the object Cha Halpha 1, located in the Chamaeleon I star-forming cloud, show that it is a approximately 10(6)-year-old brown dwarf with spectral type M7.5 to M8 and
XMM-Newton probes the stellar population in Chamaeleon I South
We report on a 30 ks XMM-Newton observation of the central region of the Cha I star forming cloud. The field includes a substantial fraction of the known pre-main-sequence population of Cha I South,
The X-Ray Emission from Pms Stars in Taurus-Auriga, and the Relationship with Other Diagnostics of Activity
We present a systematic study of the X-ray emission of pre-main-sequence stars in the Taurus-Auriga complex; the sample consists of all catalogued stars in this region observed with the Einstein
X-ray emission from young stars in Taurus-Auriga-Perseus: Luminosity functions and the rotation - activity - age - relation
We report on a systematic search for X-ray emission from pre-main sequence and young main sequence stars in the Taurus-Auriga-Perseus region. Our stellar sample consists of all T Tauri stars from the
ROSAT X-ray Study of the Stellar Population of the Chamaeleon I Dark Cloud
Two soft X-ray images of the Chamaeleon I cloud obtained with the ROSAT PSPC are presented. Seventy reliable, and perhaps 19 additional X-ray sources are found. Up to 90% of these sources are
Settling onto the Main Sequence: ROSAT Observations of H and χ Persei
We have studied X-rays from the double cluster h and χ Per with an 11 ks ROSAT position-sensitive proportional counter (PSPC) observation. Emission is concentrated toward the two cluster centers.
