WHO I AM: I
came to Cornell University from Moscow, Russia in 1996 from active
astrophysics group led by academician Zeldovich. I learned a lot from
members of the group, in particular from Prof. Bisnovatyi-Kogan and Dr.
Illarionov. In Cornell I learned plasma astrophysics from Prof.
Lovelace.
WHAT I AM DOING: I
am leading 2.5D (axisymmetric) and 3D numerical simulations in Cornell Plasma
Astrophysics group, and in the
US-Russia collaborative research team.
Also I am doing lots of simulations/visualizations myself and work in a
number of interesting directions. I
enjoy to guide two Cornell graduate students, Akshay Kulkarni and Min
Long who are doing a lot of nice computing work.
MAIN
RESEARCH INTERESTS: Numerical simulations of the disk accretion
to a star with a dipole or more complex magnetic fields, investigation of the funnel
flows, application to T Tauri stars, comparison of theoretical models
with spectra of T Tauri stars. Investigation of the
"propeller"
stage of evolution of T Tauri stars. Application of the disk-magnetosphere
interaction models to accreting neutron stars and cataclysmic variables.
Theoretical and numerical investigation of different
stages of evolution of isolated neutron stars. Accretion
to magnetic dipole: spherical Bondi
accretion, accretion in the "propeller"
regime. Modeling of
propagation of magnetized neutron stars
through the ISM. Observability of isolated neutron stars.
The
origin of astrophysical jets.
MHD simulations and analysis of magneto-centrifugally driven jets and
outflows from the disk. Collimation of outflows. Numerical modeling of evolution of magnetic loops
threading an accretion disk.
