There are 1 comment on the Tehran Times story from Oct 6, 2012, titled UCLA astronomers discover star racing around black hole at center of our galaxy. In it, Tehran Times reports that:

UCLA astronomers report the discovery of a remarkable star that orbits the enormous black hole at the center of our Milky Way galaxy in a blistering 11-and-a-half years - the shortest known orbit of any star near this black hole.

Beginning to look like a wasp nest in there.

be interesting to know of the mass and type of the stars.

If they are red giants tidal stripping may occur at close pass.

Low mass stars may also (as they are ionised plasma) may be affected by the ferocious magnetic field associated with the "drag & spin" disc of the central black hole. The orbit will as a result decay if they orbit anti spin and circularise with time if they orbit pro spin.

This is an important process (see galaxy M104 with central black hole with low precession rate). As Milky way black hole is unmerged it precesses in all 3 axes (disco mode) so orbits of stars will vary versus the drag & spin disc around the equatorial plane of the black hole as the drag & spin disc precesses.

Black hole is also about to munch a protoplanetary disc from one of the newly formed ring stars Looks interesting in there but a lot of buzz & sting to come I think.

Have a nice day: Ag
