Star Formation: Lessons from Taurus
The Taurus molecular cloud complex is the paradigm for quiescent, low-density, isolated star formation. Yet the age distribution of its stellar population indicates that star formation is a rapid and dynamic process, inconsistent with the old picture of magnetically-controlled protostel-lar cloud collapse. Instead, Taurus seems to have formed stars in a manner qualitatively consistent with the ...
متن کاملNew Pre-Main Sequence Candidates in the Taurus-Auriga Star Forming Region
Aims. We have studied the X-ray source population of the Taurus Molecular Cloud (TMC) to search for new members of the Taurus-Auriga star forming region. Methods. Candidate members have been selected among the X-ray sources detected in 24 fields of the XMM-Newton Extended Survey of the Taurus Molecular Cloud, having an IR counterpart in the 2MASS catalog, based on color-magnitude and color-colo...
متن کاملLuminous Red Variable Star
We report photometry and spectroscopy of the evolution of Nova Sagittarii 1994 #1 (V4332 Sagittarii) during outburst. We compare the photometric and spectral evolution of this outburst to known classes of outbursts – including classical novae and outbursts occurring on symbiotic stars – and find this object does not conform to any known class of outburst. The closest match to the behavior of th...
متن کاملEjection of a Low Mass Star in a Young Stellar System in Taurus
We present the analysis of high angular resolution VLA radio observations, made at eleven epochs over the last 20 years, of the multiple system T Tauri. One of the sources (Sb) in the system has moved at moderate speed (5-10 km s−1), on an apparently elliptical orbit during the first 15 years of observations, but after a close (< 2 AU) encounter with the source Sa, it appears to have accelerate...
متن کاملA Multiwavelength Study of Star Formation in the L1495E Cloud in Taurus
We have carried out a deep (t=30000s) x-ray search of the eastern portion of the L1495 cloud centered on the well known weak line T Tauri star (WTTS) V410 Tau using the ROSAT PSPC. This deep exposure enabled a search for candidate pre-main sequence (PMS) objects in this cloud to a limit ∼ 20 times more sensitive than that typical of the fields examined with the Einstein searches. Despite assert...
