Scientific paper

The authors present an evolutionary scenario for the black hole binary A 0620-00, which starts from an initial configuration consisting of a massive star and a low-mass companion in a very wide orbit. By using the presently observed system parameters and following the evolution backward in time, the authors derive an upper limit to the initial mass of the companion of 2 M_sun;, a relation between the present mass of the black hole and the mass of its main-sequence progenitor, which, for the most likely black hole mass of 7 M_sun;, yields a progenitor mass between 27 and 46 M_sun; and a lower limit on the initial orbital period of 240 days.
