Scientific paper

We propose to use HETGS observations to investigate the accretion and outflow mechanisms in the underluminous supermassive black hole in M81*. We expect to identify and measure the radial infall velocity of the H-like and He-like iron emission originating from hot plasma closest to the black hole. We will measure the radiative efficiency of accretion from radio polarimetry and test if photoionization is heating the hot plasma. We wish to establish the intraday variability in the source and search for X-ray flares, which will allow us to constrain theoretical models of low-efficiency accretion or outflow.
