X-ray flares from Sgr A*: star-disk interactions?
Sergei Nayakshin, Jorge Cuadra, Rashid Sunyaev
Sgr A*, the putative black hole in our Galactic Center (GC), is extraordinary dim in all frequencies. Apparently the black hole is unable to accrete at the Bondi accretion rate for…
Bright stars and an inactive disk in Sgr A* and other dormant galaxy centers. I. The optically thick disk
Jorge Cuadra, Sergei Nayakshin, Rashid Sunyaev
Cold inactive disks are believed to exist in Low Luminosity AGN (LLAGN). They may also exist in the nuclei of inactive galaxies and in the center of our own Galaxy. These disks wou…
The frozen (inactive) disk in Sgr A: freezing the accretion of the hot gas too?
Sergei Nayakshin
The black hole in our Galactic Center is extremely underluminous for the amount of hot gas available for accretion. Theoretical understanding of this fact rests on a likely but not…
Close stars and an inactive accretion disk in Sgr A*: Eclipses and flares
Sergei Nayakshin, Rashid Sunyaev, .
A cold neutral and extremely dim accretion disk may be present as a remnant of a past vigorous activity around the black hole in our Galactic Center (GC). Here we discuss ways to d…
