Shashikumar Madhusudan Chitre
Shashikumar Madhusudan Chitre, Indian astrophysicist (Mumbai 07 May 1936 – Mumbai 11 January 2021) Considered one of the leading international researchers in astrophysics Made seminal contributions to understanding of solar oscillations in terms of the internal structure of the sun With J.V. Narlikar proposed the hypothesis of the gravitational curvature of radio waves due to the presence of galaxies (1978) Mapped the differential rotation of the solar interior Measured heavy elements abundances in the solar interior With Saslaw & Narasimha discovered Einstein rings SOME BIBLIOGRAPHY The Structure of Sunspots.
