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
