A cold neutral and extremely dim accretion disc may be present as a remnant of past vigorous activity around the black hole at our Galactic Centre (GC). Here we discuss ways to detect such a disc through its interaction with numerous stars present in the central 0.01 pc of the Galaxy. The first major effect expected is X-ray and near-infrared (NIR) flares arising when stars pass through the disc. The second is eclipses of the stars by the disc. We point out conditions under which the properties… 
Using close stars as probes of hot accretion flow in Sgr A
The extremely hot and tenuous accretion flow in the immediate vicinity of Sgr A ∗ is believed to be invisible (too dim) in the X-ray band, except for short X-ray flares. Here we point out that during
Close stars and accretion in low-luminosity active galactic nuclei
TLDR
It is found that, despite 'low' luminosities of LLAGNs, unrealistically high stellar densities are required to make a sizable radiative contribution to the Hubble Space Telescope optical/ultraviolet spectra of these galactic nuclei.
Low angular momentum accretion flow model of Sgr A* activity
Sgr A* is a source of strongly variable emission in several energy bands. It is generally agreed that this emission comes from the material surrounding the black hole which is either falling in or
On highly eccentric stellar trajectories interacting with a self-gravitating disc in Sgr A
We propose that Kozai's phenomenon is responsible for the long-term evolution of stellar orbits near a supermassive black hole. We pursue the idea that this process may be driven by a fossil
Enhanced activity of massive black holes by stellar capture assisted by a self-gravitating accretion disc
Aims. We study the probability of close encounters between stars from a nuclear cluster and a massive black hole (10 4 MM• 10 8 M� ). The gravitational field of the system is dominated by the black
Stellar Processes Near the Massive Black Hole in the Galactic Center
A massive black hole resides in the center of most, perhaps all galaxies. The one in the center of our home galaxy, the Milky Way, provides a uniquely accessible laboratory for studying in detail the
X-ray flares reveal mass and angular momentum of the Galactic Center black hole
We have analysed the light curve of the two brightest X-ray flares from the Galactic Center black hole, one flare observed by XMM-Newton on October 3, 2002 (Porquet et al. \cite{P2003}), and the
Impulsive Electromagnetic Emission near a Black Hole
The electromagnetic signature of a point explosion near a Kerr black hole (BH) is evaluated. The first repetitions produced by gravitational lensing are not periodic in time; periodicity emerges only
Radio Variability of the Sagittarius $ {\rm A^*}$ due to an Orbiting Star
Recently, unprecedentedly accurate data on the orbital motion of stars in the vicinity of the Sagittarius $ {\rm A^*}$ have been available. Such information can be used not only to constrain the mass
The extreme luminosity states of Sagittarius A
We discuss mm-wavelength radio, 2.2–11.8 μm NIR and 2–10 keV X-ray light curves of the super massive black hole (SMBH) counterpart of Sagittarius A* (SgrA*) near its lowest and highest observed

A star in a 15.2-year orbit around the supermassive black hole at the centre of the Milky Way
TLDR
Ten years of high-resolution astrometric imaging allow us to trace two-thirds of the orbit of the star currently closest to the compact radio source (and massive black-hole candidate) Sagittarius A* and show that the star is on a bound, highly elliptical keplerian orbit around Sgr A*.
Rapid X-ray flaring from the direction of the supermassive black hole at the Galactic Centre
TLDR
The discovery of rapid X-ray flaring from the direction of Sagittarius A* provides compelling evidence that the emission is coming from the accretion of gas onto a supermassive black hole at the Galactic Centre.
