Formation of metal-free binaries: Impact of H line cooling and CIE cooling
Rafeel Riaz, Dominik R. G. Schleicher, Stefano Bovino +2
During primordial star formation, the main cooling channel is provided by H and super-molecules, such as H or H, at sufficiently high densities. When the latter f…
Turbulence and its connection to episodic accretion in binary YSOs
Rafeel Riaz, Dominik R. G. Schleicher, Siegfried Vanaverbeke +1
We report signatures of episodic accretion in young stellar objects (YSOs) that emerge in protobinary configurations in a gravoturbulent gas collapse. We find in most of these prot…
Stellar Initial Mass Function over a range of redshifts
Rafeel Riaz, Dominik R. G. Schleicher, Siegfried Vanaverbeke +1
The stellar Initial Mass Function (IMF) seems to be close to universal in the local star-forming regions. However, this quantity of a newborn stellar population responds differentl…
Do fragmentation and accretion affect the stellar Initial Mass Function?
R. Riaz, D. R. G. Schleicher, S. Vanaverbeke +1
While the stellar Initial Mass Function (IMF) appears to be close to universal within the Milky Way galaxy, it is strongly suspected to be different in the primordial Universe, whe…
Formation of massive black holes via collisions and accretion
D. R. G. Schleicher, M. A. Fellhauer, T. Boekholt +13
To explain the observed population of supermassive black holes at z~7, very massive seed black holes or, alternatively, super-Eddington scenarios are needed to reach final masses o…
The formation of protostellar binaries in primordial minihalos
Rafeel Riaz, Stefano Bovino, Siegfried Vanaverbeke +1
The first stars are known to form in primordial gas, either in minihalos with about ~M or so-called atomic cooling halos of about ~M. Simulations have s…
