File table1 contains the list of the 212 ISOCAM sources recognized as members of the rho Ophiuchi embedded cluster. It lists their J2000 coordinates, flux densities at 6.7 and...

We present a second update of the Arcetri Catalog of water masers (Comoretto et al., 1990A&AS...84..179C; Brand et al., 1994, Cat. ). The present study reports the results...

We have performed the first detailed spatially resolved spectroscopy of Cas A in the 1.6-10keV energy range, using data taken with the Medium Energy Concentrator Spectrometer...

Detailed atmospheric abundances have been calculated for a sample of A-G supergiant stars with IR fluxes and/or high galactic latitudes. HD 172481 and HD 158616 show clear...

We present observations of the region between 5{deg}<=l<=45{deg} and |b|<=3{deg}, in the OH 1612.231MHz line, taken from 1993 to 1995 with NRAO's Very Large Array...

We carried out a systematic search for nearby dwarf galaxies in the northern sky based on POSS-II film copies. As a result we present a list of 101 nearby dwarf galaxy...

We have used the Nancay Radio Telescope to obtain new global HI data for 16 giant low surface brightness (LSB) galaxies. Our targets have optical luminosities and disk scale...

To investigate the distance and linear dimensions of the Draco Molecular Cloud (MBM 41) we have obtained new CCD photometry for a selection of stars in 20 selected areas toward...

The 7 and 15{mu}m observations of the Galaxy obtained by the ISOGAL program offer an unique possibility to investigate and separate the different populations of stars in the...

We surveyed 81 dense molecular cores associated with regions of massive star formation and Sgr A in the J_(K_-1_K_1_)=5_(05)-4_(04) and 10(010)-9_(09) lines of HNCO. Line...

We present a photometric study of the compact HII region Sh2-88B and its associated stellar cluster. The positions and JHKmagnitudes are obtained for 125 stars over an 80"x80"...

We have obtained two deep exposures of the {rho} Oph cloud core region with the ROSAT High Resolution Imager. The improved position accuracy (1"-6") with respect to previous...

We present multiband photometric observations of three spiral galaxies selected in a sample suited for the study of young stellar groupings and their relationship with the...

We present the results of an ISOCAM survey of the Chamaeleon I dark cloud conducted in two broad-band filters at 6.7 and 14.3{mu}m. In an area of 0.59deg^2^. we have detected a...

Sub-arcsecond JHK images of the star formation region NGC 6334 IV covering 14.7arcmin^2^ have been obtained. These were supplemented by H_2_ and Br{gamma} images of the central...

The table shows clump parameters for 130 peaks in CO(J=1->0) emission detected in the Lambda-Orionis ring in the survey of Lang et al. (1998PASA...15...70L). The clumps were...

From an H-{alpha} image of the spiral barred galaxy NGC 3359, an HII region catalogue is composed. The catalogue comprises the position, mean radius and the calibrated H-alpha...

This table contains the dust temperatures and dust-to-gas mass ratios derived for a sample of planetary nebulae and the observational data used for these determinations

We are searching for Young Stellar Objects (YSOs) near the boundary between protostars and pre-main-sequence objects, what we term Transitional YSOs. We have identified a sample...

DENIS observations in the J(1.25{mu}m) and K_S_(2.15{mu}m) bands together with isochrones calculated for the RGB and AGB phase are used to draw an extinction map of the inner...
