Shashikumar Chitre

Shashikumar Madhusudan Chitre FNA, FASc, FNASc, FRAS (7 May 1936 – 11 January 2021) was an Indian mathematician and astrophysicist, known for his research in Astronomy and Astrophysics. The Government of India honored him, in 2012, with Padma Bhushan, the third highest civilian award, for his services to the sciences.

Biography Illustration of the dynamo mechanism that creates the Earth's magnetic field: convection currents of magma in the Earth's outer core, driven by heat flow from the inner core, organized into rolls by the Coriolis force, creates circulating electric currents, which generate the magnetic field.

Shashikumar Chitre graduated in Mathematics from the Elphinstone College, Mumbai, in 1956, on completion of which he was awarded the Duke of Edinburgh Scholarship to study abroad. He joined Peterhouse, University of Cambridge and did another bachelor's degree in 1959. In 1960, he was selected as the Peterhouse Scholar, with which he completed his master's degree. Subsequently, he got selected for Gulbenkian Research studentship, moved to Churchill College and obtained his PhD from the Department of Applied Mathematics and Theoretical Physics of Cambridge, in 1963.

Chitre started his career as a lecturer at the University of Leeds, in 1963, and worked there till 1966 when he obtained another fellowship to join the California Institute of Technology, Pasadena. In 1967, he returned to India and joined the faculty of Tata Institute of Fundamental Research, which served as the base of his research till his retirement in 2001.

Research highlights Chitre's scientific research was focused on solar physics, astrophysics and gravitational lensing. He performed extensive research on the Sun's magnetic activity cycle, the solar dynamo theory, and the role of neutrinos in the solar atmosphere.
