Measuring the mass exchange in the pulsating ultraluminous x-ray source M82 X-2
Abstract
M82 X-2 is the first discovered pulsating ultraluminous x-ray source (PULX), and the one with the shortest orbital period. The luminosity of this object seems to imply a high mass accretion rate, probably due to Roche Lobe overflow. If so, this mass exchange is bound to produce visible changes of the orbital period in a relatively short time. I present a new, precise orbital solution for this system, and discuss the implications on the total mass exchange of the system.
