Star Formation and Self-Regulated Dynamics of Long, Dense Molecular Filaments
Andi Burkert USM/LMU, Munich, DE | |
| Long, dense molecular filaments like Nessie are often dubbed the bones or the sceleton of the Milky Way. Their coherence and longevity are still a theoretical puzzle. In this contribution I would like to discuss a dynamical model of Nessie-like filaments which assumes gas, flowing through an elongated density wave as expected in spiral arms. The gas is being compressed and condenses into stars and stellar clusters. Stellar feedback disrupts the structure locally. However fresh gas inflow rejuvinates this segment of the filament again, generating a long-lived structure. I will argue that these long filaments provide deep insight into dynamical processes in the galactic disks. They also might play an important role in driving turbulence in the interstellar medium and in generating massive stellar clusters. | |
