On the nature of dust clouds in the region towards M81 and NGC3077
Andreas Heithausen
There is some controversy on the nature of dust clouds found in direction of the interacting galaxy triplett M81, M82, and NGC3077. Are they associated with the tidal arms seen in…
A candidate protostellar object in the L1457 / MBM12 cloud
Andreas Heithausen, Christoph Böttner
The association of young T Tauri stars, MBM12A, indicates that L1457 was forming stars not too long ago. With our study we want to find out whether or not there are still signs for…
Chemical and physical small-scale structure in a pre-stellar core
Andreas Heithausen, Christoph Boettner, Fabian Walter
We present a comparative study of several molecular lines and of the dust contiunuum at 1.2mm in a pre-stellar core that is embedded in the Galactic cirrus cloud MCLD123.5+24.9. Pr…
An unbiased deep search for small-area molecular structures
Andreas Heithausen
Small-area molecular structures (SAMS) resembling those clumpuscules, proposed by Pfenniger and Combes (1994) as candidate for baryonic dark matter, have recently been detected (He…
Molecular hydrogen as baryonic dark matter
Andreas Heithausen
High-angular resolution CO observations of small-area molecular structures (SAMS) are presented. The feature-less structures seen in the single-dish measurements break up into seve…
Cold dust and its relation to molecular gas in the dwarf irregular galaxy NGC 4449
C. Boettner, U. Klein, A. Heithausen
We present observations of the dwarf irregular galaxy NGC 4449 at 850 m and 450 m obtained with SCUBA at the JCMT. The distribution of the cold dust agrees well with that of…
