1. (S-7a) The Black Hole at the Center of our Galaxy
... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

4. Dust evolution across the CO snowline in a protoplanetary disk
... General information . ... Staff . Research staff . ... Information . ... Historical highlights . Historical research . ... This process is thought to occur in circumstellar disks of gas and dust around young stars on rather short timescales : infrared surveys show that the number of low mass stars with disks drops dramatically for stars older than 10 Myr, suggesting that in order to form large solids before the disk disperses, the growth process has to take place within a few million years. ...

10. Black holes in galactic nuclei - Figure 2
HST images of the nuclear gas and dust disk in NGC 7052. The top panel shows a true-color composite HST image, with a ground-based image as inset. The bottom panel shows false color images in, from left to right: I-band, B-I, H_alpha + [NII] (ionized gas). The gas kinematics inferred from HST/FOS spectra suggest a nuclear BH of 3 x 10^8 solar masses ( [R13] , [R22] ). See the Space Telescope Science Institute Press Release for more information. ...

... The event horizon is the boundary of a black hole) . ... When the supermassive star implodes (collapses under it?s own gravity) a black hole is formed. Many black holes have been found in the centres of galaxies. ... It was thought that black holes don?t give out any energy at all (except when engulfing stars). ... It is thought that as the stars pass near to the centre, they are pulled in by the black hole and forced to remain orbiting around the black hole. ...

Next: Binary Radiopulsars with Black Up: Black Holes in Binaries Previous: Black Holes in Binaries . Two different types of stellar BH formation exist: (1) direct core collapse   of a massive star and (2) AIC of a NS. A BH of the first type presumably will have a mass comparable to that of the collapsing star and can be born both from a single star and in a binary system. ...

15. Evidences of supercritical accretion onto black hole in SS433
... SS433 is a close binary system, one star is a supergiant, a second one is a black hole. ... Even a black hole cannot accept such an enormous mass flux, a supercritical accretion disk appears, all the excess gas glows up to several tens of thousands degrees and is ejected off the disk with enormous velocities. ... SAO researchers have found an evidence of the supercritical accretion onto a black hole in SS433, which follows from a brightness variability of the SS433 disk. ...
