LECTURE SERIES ON NEUTRON STARS

4 lectures for graduate students, held at ESO Vitacura (Chile) on October 23-27, 2006 (in English)

1: Basics
- History: prediction of neutron stars, discovery of pulsars, how we know they are neutron stars
- Theory: Degenerate fermions, weak interaction equilibrium, equation of state, white dwarfs vs. neutron stars, Chandrasekhar limit, possible exotic forms of matter, neutron star structure
PRESENTATION

2: Phenomenology
- Classical and millisecond pulsars, high-mass and low-mass X-ray binaries, magnetars, thermal emitters, "RRATs"
- What can be observed, how physical properties can be inferred, what are the similarities, differences, and connections among all these objects
PRESENTATION

3: Thermal evolution
- cooling processes in young neutron stars: neutrino and photon emission, direct vs. modified Urca processes, effects of superfluidity and different equations of state, observational constraints
- heating processes in old neutron stars: crust cracking, vortex motion, rotochemical and gravitochemical heating, constraints on variations of the gravitational constant
PRESENTATION

4: Magnetic field
- the origin of the magnetic field, possible connections to main sequence stars and white dwarfs
- magnetic field evolution: magnetars, young vs. old neutron stars, physical processes in isolated and accreting neutron stars
PRESENTATION

 

Shortened & updated version for graduate course “Topics in Astrophysics”, November 2009

1: Basics - 2: Phenomenology - 3: Thermal evolution - 4: Magnetism
