ISO far infrared observations of the high latitude cloud L1642. II. Correlated variations of far-infrared emissivity and temperature of "classical large" dust particles
K. Lehtinen, M. Juvela, K. Mattila +2
Our aim is to compare the infrared properties of big, ``classical'' dust grains with visual extinction in the cloud L1642. In particular, we study the differences of grain emissivi…
Scattered H-alpha light from Galactic dust clouds
K. Mattila, M. Juvela, K. Lehtinen
Bright emission nebulae, or HII regions, around hot stars are readily seen in H-alpha light. However, the all-pervasive faint H-alpha emission has only recently been detected and m…
Properties of dust in the high-latitude translucent cloud L1780 I: Spatially distinct dust populations and increased dust emissivity from ISO observations
M. Ridderstad, M. Juvela, K. Lehtinen +2
We have analyzed the properties of dust in the high galactic latitude translucent cloud Lynds 1780 using ISOPHOT maps at 100 and 200 micrometers and raster scans at 60, 80, 100, 12…
The ratio of N(C18O) and Av in Chamaeleon I and III-B using 2MASS and SEST
J. Kainulainen, K. Lehtinen, J. Harju
We investigate the relationship between the C18O column density and the visual extinction in Chamaeleon I and in a part of the Chamaeleon III molecular cloud. The C18O column densi…
Far infrared observations of pre-protostellar sources in Lynds 183
K. Lehtinen, K. Mattila, D. Lemke +3
Using ISOPHOT maps at 100 and 200um and raster scans at 100, 120, 150 and 200um we have detected four unresolved far-infrared sources in the high latitude molecular cloud L183. Two…
Far-infrared and molecular line observations of Lynds 183 - studies of cold gas and dust
M. Juvela, K. Mattila, K. Lehtinen +3
We have mapped the dark cloud L183 in the far-infrared at 100um and 200um with the ISOPHOT photometer aboard the ISO satellite. The observations make it possible for the first time…
