'Discs round Stars and in Galaxies' - A look at how discs form and some of the things they do in binary star systems and Active Galactic Nuclei.
The areas discussed include:
Why discs? | How discs form from a cloud of dust and gas; the galactic bulge; globular clusters |
Accretion Disc Formation | Roche equipotentials; Roche lobes; reasons for overflow from secondary to primary; drift onto primary |
What can we see on the disc? | Secondary; primary esp. white dwarf; hot spot; boundary layer; disc itself |
Eclipses | What we can see as the (red dwarf) secondary eclipses the primary (white dwarf), hot spot and disc |
Novae and Supernovae | Dwarf novae; anti-dwarf novae; regular novae; supernova Type Ia |
Magnetic Field Effects | Polars; intermediate polars; propellers |
AGN Discs | Eddington rate; Eddington luminosity; efficiency; amount of matter being consumed |
Black Hole at Centre of AGN | Disruption of stars; size of black hole; singularity |
