Mass accretion rate of the galactic black hole A0620-00 in its quiescent state.

PAL S. and CHAKRABARTI S.K.

Abstract (from CDS):

Our recent radio observation using the Giant Meter Radio Telescope (GMRT) of the galactic black hole transient A0620-00 at 1.280GHz revealed a micro-flare of a few milli-Jansky. Assuming an equipartition of magnetic energy and the gravitational potential energy of accreting matter, it is possible to estimate the upper limit of the accretion rate. Assuming a black hole mass of 10M☉ residing at the center, we find this to be at most {dot}(M)=(8.5±1.4)x10–11M☉/yr. This is consistent with earlier estimates of accretion rates based on optical and X-ray observations.
