We report on new aspects of the star-forming region S235AB revealed through high-resolution observations at radio and mid-infrared wavelengths. Using the Very Large Array, we...

The Two Micron All Sky Survey (Cat. ), along with the Stellar Population Synthesis Model of the Galaxy, developed in Besancon, is used to calculate the extinction distribution...

L-band data of RCW 57 at 3.5 micron taken with SPIREX (South Pole Infrared Explorer) is presented. The photometry was combined with 2MASS JHK data at 1.25 -2.2 micron....

High sensitivity 21-cm HI line observations with an rms noise level of ~0.5mJy were made of 35 spiral galaxies in the Coma Supercluster, using the refurbished Arecibo telescope,...

The absorption spectra of the olivine particles of different Mg/Fe content were measured in the infrared spectral region between 5 and 100{mu}m, while the particles were...

In an ongoing effort to identify and study high-mass protostellar candidates we have observed in various tracers a sample of 235 sources selected from the IRAS Point Source...

An infrared study that includes ground-based mid-infrared images between 8.7 and 18.7um and IRAC images at 3.6, 4.5, 5.8 and 8.0um of the W75 N massive star forming region is...

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...

We have observed two rotational transitions of both CS and C^17^O, and the 1.2mm continuum emission towards a sample of 130 high-mass protostellar candidates with...

We present observations of the infrared fine-structure lines of [Si II] (34.8{mu}m), [O I] (63.2 and 145.5{mu}m) and [C II] (157.7{mu}m) obtained with the ISO SWS and LWS...

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...

This catalog is an up-date of Wu et al., 1996, Cat. . Cone search capability for table J/A+A/426/503/table1a (CO outflows, and their basic parameters)

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...

We present the results of mapping observations with ISO of [OI]63{mu}m, 145{mu}m, [NII]122{mu}m, [CII]158{mu}m, [SiII]35{mu}m, and H_2_9.66{mu}m line emissions for the Carina...

Laboratory detection of four isomers of C_5_H_2_ molecule have been reported by Travers et al. (1997ApJ...483L.135T), McCarthy et al. (1997, Science, 275, 518), and Gottlieb et...

In this paper, we report new observations and derive chemical abundances for a sample of 26 planetary nebulae (PN) located in the anti-center direction. Most of these nebulae...

We present the oxygen abundance determination for 90 HII regions in the inner parts of the grand design galaxy M101. The abundances were derived employing the P method...

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...

We study the Large Magellanic Cloud Papillon Nebula (N 159-5), a conspicuous High Excitation Blob (HEB) lying in the star forming complex N 159. Using JHK near-infrared...

We present results from an ISOCAM survey in the two broad band filters LW2 (5-8.5{mu}m) and LW3 (12-18{mu}m) of a 0.13 square degree coverage of the Serpens Main Cloud Core. A...
