Protostellar disk accretion in turbulent filaments
Stefan Heigl, Elena Hoemann, Andreas Burkert
Recent observations of protostellar cores suggest that most of the material in the protostellar phase is accreted along streamers. Streamers in this context are defined as velocity…
Filament fragmentation: Density gradients suppress end dominated collapse
Elena Hoemann, Stefan Heigl, Andreas Burkert
The onset of star formation is set by the collapse of filaments in the interstellar medium. From a theoretical point of view, an isolated cylindrical filament forms cores via the e…
Filament collapse: a two phase process
Elena Hoemann, Stefan Heigl, Andreas Burkert
Using numerical simulations, we investigate the gravitational evolution of filamentary molecular cloud structures and their condensation into dense protostellar cores. One possible…
Taking off the edge -- simultaneous filament and end core formation
Stefan Heigl, Elena Hoemann, Andreas Burkert
Simulations of idealised star-forming filaments of finite length typically show core growth which is dominated by two cores forming at its respective end. The end cores form due to…
Merging Filaments I: A race against collapse
Elena Hoemann, Stefan Heigl, Andreas Burkert
The interstellar medium is characterised by an intricate filamentary network which exhibits complex structures. These show a variety of different shapes (e.g. junctions, rings, etc…
