What are the stars? (Lecture - 03) by G Srinivasan
Показать описание
Time: 10:00 AM
Venue: Ramanujan Lecture Hall / Madhava Lecture Hall, ICTS Campus, Bangalore
This summer course aims to give a broad perspective on gravity, astrophysics and cosmology and is suitable for advanced undergraduates and graduate students in physics and astronomy. Professor G Srinivasan is a specialist in Condensed matter Physics and Astrophysics and is an excellent teacher. After acquiring his PhD from the University of Chicago in 1970, he had a distinguished career as a scientist and teacher at the IBM Research Laboratory, Chalmers University of Technology, University of Cambridge, and Raman Research Institute. He has done pioneering work in condensed matter physics and astrophysics, and is the author of the best selling popular science books “What Are The Stars?” and “Can Stars Find Peace?”.
Topics:
L1 : Einstein's Theory of Relativity
L 2 : Principles of Radiative Transfer
L 3 : What are the stars?
L 4 : The solar neutrino puzzle.
L 5 : White Dwarfs as Quantum stars.
L 6 : Neutron Stars.
L 7 : Pulsars
L 8 : Black Holes I
L 9 : Black Holes II
L 10 : Between the stars.
L 11 : Supernovae
L 12 : Contemporary Cosmology I
L 13 : Contemporary Cosmology II
0:00:00 A Journey through the Universe
0:00:08 What are the stars? (Lecture-03)
0:02:10 Stars as globes of perfect gas
0:03:54 Gravitational Force
0:06:31 Hydrostatic Equilibrium
0:09:40 Boyle's Law
0:11:14 Equation of Hydrostatic Equilibrium
0:11:55 What are the stars?
0:12:58 Eddington's theory of stars
0:13:52 Radiation Pressure
0:14:09 Hydrostatic Equilibrium
0:16:05 The interior of the Sun
0:29:31 Mass - Luminosity relation
0:31:26 Mass - Luminosity relation calculated by Eddington
0:32:26 Luminosity of a star depends only on its mass!
0:33:23 Why are the stars as they are?
0:33:45 To Eddington this 'agreement' was most annoying! "What business have they on a curve reserved for a perfect gas?", he exclaimed.
0:37:28 "Our mistake was that in estimating the congestion in the stellar ball-room we had forgotten that crinolines are no longer infashion" - Eddington
0:43:07 Eddington was obscure about two things:
0:44:57 The Bohr radius
0:48:36 Lifetime of stars
0:49:16 Element & Relative Mass(percent)
0:49:46 Why does the Sun shine?
0:51:41 Virial Theorem applied to the Sun
0:51:56 How long will the heat last?
0:53:59 Sir Arthur Eddington 24 August, 1920
0:59:37 Mass Deficit
1:02:31 Proton - proton collision
1:06:18 Maxwell-Boltzmann Distribution
1:08:15 Alpha decay of radioactive nuclei
1:11:56 Quantum Tunnelling
1:14:14 Energy production in the Sun
1:19:27 Why doesn't the Sun blow up?
1:20:28 The Safety Valve
1:23:12 Nuclear cycles
1:25:33 To burn or not to burn? That is the question
1:28:24 Fusion reactions
1:29:19 The composition of the core when nuclear reactions finally stop
1:31:34 Q&A
