NIR imaging of HH 223
The dark cloud Lynds 723 (L723) is a low-mass star-forming region where one of the few known cases of a quadrupolar CO outflow has been reported. Two recent works have found... -
CO maps in Serpens
The Serpens North cluster is a nearby low mass star forming region which is part of the Gould belt. It contains a range of young stars thought to correspond to two different... -
Sensitivity analysis list of chemical reactions
Because of new telescopes that will dramatically improve our knowledge of the interstellar medium, chemical models will have to be used to simulate the chemistry of many regions... -
Low-mass population in {rho} Oph cloud
Star formation theories are currently divergent regarding the fundamental physical processes that dominate the substellar regime. Observations of nearby young open clusters... -
NGC 6334-NGC 6357 complex
Our knowledge of high-mass star formation has been mainly based on follow-up studies of bright sources found by IRAS, and has thus been incomplete for its earliest phases, which... -
Extended red(dened) regions in 2MASS
The aim of this paper is to identify extended red regions in the outer galactic plane based on reddening of stars in the near-infrared. We argue that these regions appear... -
Catalog of high extinction clouds
The earliest phases of massive star formation are found in cold and dense infrared dark clouds (IRDCs). Since the detection method of IRDCs is very sensitive to the local... -
Dust coagulation in molecular clouds
The cores in molecular clouds are the densest and coldest regions of the interstellar medium (ISM). In these regions ISM-dust grains have the potential to coagulate. This study... -
Young T Tauri star in CB 26 molecular outflows
The disk-outflow connection is thought to play a key role in extracting excess angular momentum from a forming proto-star. Although jet rotation has been observed in a few... -
A search for pre-biotic molecules
Low-noise, 0.8MHz resolution spectra around 90GHz towards four hot core sources: Orion KL, W51 e1/e2, S140, and W3(OH), are presented. The observations were performed using the... -
N2H+(1-0) maps of Ophiuchus main cloud
The earliest phases of clustered star formation and the origin of the stellar initial mass function (IMF) are currently much debated. In order to constrain the origin of the... -
Velocities of OMC-1 flows
Observations are reported of H_2_ IR emission in the S(1) v=1-0 line at 2.121{mu}m in the Orion Molecular Cloud, OMC1, using the GriF instrument on the Canada-France-Hawaii... -
Morphologies in the Cepheus Flare region
These tables contain the data of the cloud sample on which the study of the relationships between cloud morphology, optical and IR properties, and star formation is based. The... -
Interstellar ^12^C/^13^C ratios
The ^12^C/^13^C isotope ratio is a tracer of stellar yields and the efficiency of mixing in the ISM. ^12^CH^+^/^13^CH^+^ is not affected by interstellar chemistry, and is the... -
C^18^O/C^17^O near rho Oph
Observations of up to ten carbon monoxide (CO and isotopomers) transitions are presented to study the interstellar C^18^O/C^17^O ratio towards 21 positions in the nearby... -
H_2_ flows in rho Ophiuchi A
We present an unbiased search for molecular hydrogen emission in the L1688 cloud within the rho Ophiuchi molecular cloud complex. Our near-infrared survey covers a connected... -
IRAS 08211-4158 cluster IR photometry
We present the astrometry and near infrared photometry (H, K, L, M) of the cluster associated with the star forming region IRAS 08211-4158 in the Vela Molecular Clouds. The... -
CO abundance of 3 globules
We have studied the ratio of carbon monoxide column density to the extinction A_J_ of background field stars in the direction of three globules: B133, B335, L466. The N(CO) to... -
Infrared knots along protostellar jets
We present the near infrared spectra (0.9-2.5 micron) of protostellar jets (HH 24-26, HH72, BHR71). The observations were carried out with Sofi at R~600 with the 1x290arcsec... -
WSRT wide-field HI survey. II.
We have used the Westerbork array to carry out an unbiased wide-field survey for HI emission features, achieving an RMS sensitivity of about 18mJy/Beam at a velocity resolution...
