Gravitational collapse of polytropic, magnetized, filamentary clouds
Mohsen Shadmehri
When the gas of a magnetized filamentary cloud obeys a polytropic equation of state, gravitational collapse of the cloud is studied using a simplified model. We concentrate on the…
Variability in the stellar initial mass function at high mass: coalescence models for starburst clusters
Mohsen Shadmehri
A coalescence model using the observed properties of pre-stellar condensations (PSCs) shows how an initially steep IMF that might be characteristic of primordial cloud fragmentatio…
The Lifetimes of Molecular Cloud Cores: What is the Role of the Magnetic Field?
E. Vazquez-Semadeni, J. Kim, M. Shadmehri +1
We discuss the lifetimes and evolution of dense cores formed as turbulent density fluctuations in magnetized, isothermal molecular clouds. We consider numerical simulations in whic…
Time-dependent evolution of quasi-spherical, self-gravitating accretion flow
Mohsen Shadmehri
A self-similar solution for time evolution of quasi-spherical, self-gravitating accretion flows is obtained under the assumption that the generated heat by viscosity is retained in…
