The discovery of large numbers of young low-mass stars and brown dwarfs over the past
decade has made it possible to investigate star formation and early evolution in a previously …

Submillimeter continuum map** of the Rho Ophiuchi A cloud core reveals four compact
clumps with masses less than about 1 solar mass embedded in an arcshaped ridge of total …

This paper analyzes optical and infrared photometry of pre-main-sequence stars in the
Taurus-Aunga molecular cloud. More than half of the stars in our sample have excess near …

A comprehensive census of the stellar content of the OB associations within 1 kpc from the
Sun is presented, based on Hipparcos positions, proper motions, and parallaxes. It is a key …

We present the results of an extensive 1.3 mm continuum mosaicing study of the rho
Ophiuchi central region obtained at the IRAM 30-m telescope with the MPIfR 19-channel …

We present the results of a 1.3 mm continuum survey for cold circumstellar dust, conducted
with the IRAM 30 m telescope on a sample of over 100 young stellar objects (YSOs) in or …

A new grid of 65 faint near-infrared standard stars is presented. They are spread around the
sky, lie between 10th and 12th magnitude at K, and are measured in most cases to …

Although supernova (SN) explosions and stellar winds happen at very small scales, they
affect the interstellar medium (ISM) at galactic scales and regulate the formation of a whole …

We present a database of 264 cores mapped in the (J, K)=(1, 1) and (2, 2) lines of NH 3. We
list the core gas properties—peak positions, total ammonia column densities, intrinsic line …

We present new multiwavelength submillimeter continuum measurements of the
circumstellar dust around 48 young stars in the ρ Ophiuchi dark clouds. Supplemented with …
