RESEARCH DESCRIPTION

Besides hydrogen and helium, all other atoms that our bodies are made of must be produced inside stars. Relatively small stars like our Sun can produce up to Oxygen, heavier elements must be produced in more massive stars. I study such massive stars.

RESEARCH INTERESTS

  • Computational Astrophysics
  • Magnetohydrodynamics(MHD) Xray emission from massive stars
