Using ISOPHOT maps at 100 and 200  μ m and raster scans at 100, 120, 150 and 200  μ m we have detected four unresolved far-infrared sources in the high latitude molecular cloud L 183. Two of the sources are identified with 1.3 mm continuum sources found by Ward-Thompson et al. ([CITE], [CITE]) and are located near the temperature minimum and the coincident column density maximum of dust distribution. For these two sources, the ISO observations have enabled us to derive temperatures (~8.3 K) and…

A cold globule with a Class 0/I embedded source

Infrared observations of the dark cloud DC 303.8-14.2 and the embedded point source IRAS 13036-7644 have been made with the ISOPHOT instrument aboard ISO at 7.7 μm, 60 μm, 100 μm and 200 μm. We have

L183 (L134n) revisited. II. The dust content

We present here a complete dust map of L183 (=L134N) with opacities ranging from A V = 3 to 150 mag. Five peaks are identified as being related to known molecular peaks and among these dust peaks two

Revisiting the Magnetic Field of the L183 Starless Core

We present observations of linear polarization from dust thermal emission at 850 μm toward the starless cloud L183. These data were obtained at the James Clerk Maxwell Telescope (JCMT) using the

The initial conditions of isolated star formation — VI. SCUBA mapping of pre-stellar cores

Observations have been carried out with the Submillimetre Common-User Bolometer Array (SCUBA) at the James Clerk Maxwell Telescope (JCMT) of regions of comparatively isolated star formation in

L183 (=L134N) revisited

We report new 1.2 mm continuum observations of the L183 (=L134N) dark cloud with the MAMBO bolometer array at IRAM. Combined with ISOCAM and ISOPHOT data at 7 and 200 μ m, this new observation is not

Polarization of seven MBM clouds at high Galactic latitude

We made R-band polarization measurements of 234 stars towards the direction of MBM 33-39 cloud complex. The distance of MBM 33-39 complex was determined as $120\pm10$ pc using polarization results

Properties of dust in the high-latitude translucent cloud L1780. I. Spatially distinct dust populati

We have analyzed the properties of dust in the high galactic latitude translucent cloud Lynds 1780 using ISOPHOT maps at 100  μ m and 200  μ m and raster scans at 60  μ m, 80  μ m, 100  μ m, 120  μ

Molecular complexity in pre-stellar cores: a 3 mm-band study of L183 and L1544

Context. Pre-stellar cores (PSCs) are units of star formation. Besides representing early stages of the dynamical evolution leading to the formation of stars and planets, PSCs also provide a

Large-scale variations of the dust optical properties in the Galaxy

We present an analysis of the dust optical properties at large scale, for the whole galactic anticenter hemisphere. We used the 2MASS Extended Source Catalog to obtain the total reddening on each


We have observed the four hyperfine components of the 18 cm OH transition toward the translucent cloud eastward of Heiles Cloud 2 (HCL2E), the cold dark cloud L134N, and the photodissociation region



Far-infrared and molecular line observations of Lynds 183 - Studies of cold gas and dust

We have mapped the dark cloud L183 in the far-infrared at 100 m and 200 m with the ISOPHOT photometer aboard the ISO satellite. The observations make it possible for the rst time to study the
