The Young Stellar Cluster in the Ring Around ρ-Ophiuchi 1. Science Justification

چکیده
The interaction of newly formed stars with their parent cloud, particularly in the case of massive stars, can have significant consequences for the subsequent development of the cloud. Hot, massive stars will cause cloud disruption through their ionizing flux as well as through the momentum in their stellar winds. Yet, given the right conditions in the cloud, stellar winds may also cause the collapse of cloud cores and induce further star formation. Whether star formation happens sequentially, prompted by previous bursts of young stars, or whether stars all form in one dynamical time and disperse the cloud is under debate (Elmegreen 2000; Hartmann et al. 2001; Tassis & Mouchschovias 2004).

The initial conditions of star formation in the ρ Ophiuchi main cloud: wide-field millimeter continuum mapping
We present the results of an extensive 1.3 mm continuum mosaicing study of the ρ Ophiuchi central region obtained at the IRAM 30-m telescope with the MPIfR 19–channel bolometer array. The mosaiced field covers a total area of ∼ 480 arcmin2, corresponding to ∼ 1 pc2 at a distance of 160 pc, and includes the DCO dense cores Oph-A, Oph-B1, Oph-B2, Oph-C, Oph-D, Oph-E, and Oph-F. Our mosaic is sens...
متن کاملA Systematic Study of X-Ray Flares from Low-Mass Young Stellar Objects in the ρ Ophiuchi Star-Forming Region with Chandra
We report on the results of a systematic study of X-ray flares from low-mass young stellar objects, using two deep exposure Chandra observations of the main region of the ρ Ophiuchi star-forming cloud. From 195 X-ray sources, including class I–III sources and some young brown dwarfs, we detected a total of 71 X-ray flares. Most of the flares have the typical profile of solar and stellar flares,...
متن کاملStar Formation in the ρ Ophiuchi Molecular Cloud
A review of star formation in the Rho Ophiuchi molecular complex is presented, with particular emphasis on studies of the main cloud, L1688, since 1991. Recent photometric and parallax measurements of stars in the Upper Scorpius subgroup of the Sco-Cen OB association suggest a distance for the cloud between 120 and 140 parsecs. Star formation is ongoing in the dense cores of L1688 with a median...
متن کاملX-ray Detection from Bona-fide and Candidate Brown Dwarfs in the ρ Ophiuchi Cloud with Chandra
We present results of an X-ray search from bona-fide and candidate brown dwarfs in the ρ Ophiuchi cloud cores with the Chandra X-ray Observatory. The selected areas are two fields near the cloud center and are observed with the ACIS-I array of a 17 × 17 size and a ∼100 ks exposure. Among 18 bona-fide and candidate brown dwarfs listed by the infrared spectroscopy, we find X-ray emission from 7 s...

We present an analysis of low resolution infrared spectra for 20 brown dwarf candidates in the core of the ρ Ophiuchi molecular cloud. Fifteen of the sources display absorption-line spectra characteristic of late-type stars. By comparing the depths of water vapor absorption bands in our candidate objects with a grid of M dwarf standards, we derive spectral types which are independent of reddeni...
