Fast deuterium fractionation in magnetized and turbulent filaments
Bastian Körtgen, Stefano Bovino, Dominik R. G. Schleicher +4
Deuterium fractionation is considered as an important process to infer the chemical ages of prestellar cores in filaments. We present here the first magneto-hydrodynamical simulati…
Astrochemistry: From primordial gas to present-day clouds
Dominik R. G. Schleicher, Stefano Bovino, Bastian Körtgen +2
Astrochemistry plays a central role during the process of star formation, both in the primordial regime as well as in the present-day Universe. We revisit here the chemistry in bot…
The driving of turbulence in simulations of molecular cloud formation and evolution
Bastian Körtgen, Christoph Federrath, Robi Banerjee
Molecular clouds are to a great extent influenced by turbulent motions in the gas. Numerical and observational studies indicate that the star formation rate and efficiency cruciall…
Deuterium fractionation and H2D+ evolution in turbulent and magnetized cloud cores
Bastian Körtgen, Stefano Bovino, Dominik R. G. Schleicher +2
High-mass stars are expected to form from dense prestellar cores. Their precise formation conditions are widely discussed, including their virial condition, which results in slow c…
