Infosys-ICTS Chandrasekhar Lectures
The renowned astrophysicist Subrahmanyan Chandrasekhar worked on a variety of pathbreaking problems in his lifetime. He was awarded the Nobel Prize in 1983 for formulating theories for the creation of the ‘white dwarf’ as the hydrogen fuel of stars of a certain size runs out. The Infosys-ICTS Chandrasekhar Lecture Series are delivered by eminent physicists. The first lecture in any series is aimed at a general audience, while the remaining are targeted at specialists.
