]]> Comment on Black holes are not fed by colliding galaxies after all by Kelly Oakes http://kellyoakes.wordpress.com/2011/01/10/do-galaxy-mergers-trigger-black-hole/#comment-130 Tue, 12 Jul 2011 18:53:34 +0000 http://kellyoakes.wordpress.com/?p=285#comment-130 I don’t think that’s right – stars don’t move towards the galactic centre as they grow older. Brown dwarfs are actually “failed” stars – ones that don’t have enough mass to fuse hydrogen, and are a bit like really big planets. Red dwarfs are small (and cool) main sequence stars. A white dwarf is an end point in the life of a star that isn’t massive enough to become a neutron star or black hole.

As far as I’m aware, stars in these stages of their life can occur anywhere in the galaxy (whether they do or not is another matter, but there is no sequence that has stars moving towards the galactic centre as they get older).

gradually make their way in towards the Galactic Centre? They are born from nebulae on the outer extremities, take on mass and get larger and larger to form Brown Dwarfs, then Red Dwarfs, then Main sequence stars, before fizzling out into small heavy White dwarfs. These white dwarfs eventually explode into supernovas or become engulfed by the black hole which then spits them out as x-rays etc. By this logic, the AGNs would be those which are presently chomping on an old star, while other galactic centres are less active – because their oldest star has not reached the critical proximity.
