Neutron Stars and Blackholes (Lecture 06: Pulsars) by G Srinivasan

SUMMER COURSES

NEUTRON STARS AND BLACK HOLES

SPEAKER: G Srinivasan (​Raman Research Institute - Retired)

DATE: 15 May 2019 to 28 June 2019

VENUE: Emmy Noether Seminar Room, ICTS Bangalore
The theme of the course will be neutron stars and black holes, with emphasis on neutron stars in binaries (their formation and rotational history); their mergers; gamma ray bursts; formation of intermediate mass and super massive black holes.

Lectures:

1) Diffuse Stars
2) Life History of the stars
3) Quantum Stars
4) Neutron Stars and Supernovae
5) Interior of neutron stars
6) Superfluidity and superconductivity inside neutron stars.
7) Neutron Stars as Pulsars
8) Gravitation - From Newton to Einstein
9) Maximum mass of neutron stars
10) Evolution of neutron stars in close binaries
11) Recycled pulsars
12) Tests General Relativity using Double Neutron Stars
13) Gravitational radiation from neutron star mergers
14) Black Holes of General Relativity
15) Super massive Black Holes
16) Universe versus Multiverse


Schedule:

May – 15, 17, 22, 24, 29 and 31
June – 5, 7, 12, 14, 19, 21, 24, 26 and 28
