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…
A comparison of density structures of a star forming and a non-star-forming globule. DCld303.8-14.2 and Thumbprint Nebula
J. Kainulainen, K. Lehtinen, P. Vaisanen +2
We present a study of radial density structure of the star forming globule, DCld303.8-14.2 (DC303), and a non-star forming globule, Thumbprint Nebula (TPN), using near-infrared dat…
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…
C18O (3-2) observations of the Cometary Globule CG 12: a cold core and a C18O hot spot
L. K. Haikala, M. Juvela, J. Harju +3
The feasibility of observing the C18O (3-2) spectral line in cold clouds with the APEX telescope has been tested. As the line at 329.330 GHz lies in the wing of a strong atmospheri…
