Abstract

Massive star formation theory is not as advanced as low mass star formation. One of the main reasons for slow progress is lack of good theoretical models and observational data for early stages of massive star formation. In the last decade or so, a lot of work has been done on understanding accretion flows around young stars but much remains to be done for their massive counterparts. In this proposal, we plan on studying accretion flows around massive stars that are expected to be different from their low mass counterparts because of higher densities, mass (gravitational effects) and stronger magnetic fields that couple well to the gas (due to higher temperatures). We plan on running short-intermediate scale simulations using the publicly available code PLUTO that has been extensively used to study various astrophysical flows.
