... We are exploring the evolution of massive binary star populations for a nuclear starburst occuring in the conditions similar to the Milky Way galaxy, in its central part, on a time scale of 10 Myr. ... Our results include the number of X-ray transients (NS + main sequence star), super-accreting black holes (BHs), and binaries consisting of a BH + supergiant, all as functions of time. ... Spatial distribution of X-ray binaries at the Galactic center after the starburst . ...

... More recently, I have been concerned with observing masers located in the circumstellar shells generated by red giant stars in their mass-loss phase, and in what we can therefore learn about the late stages of stellar evolution. 100 mJy are now undetectable after ~12 years, aka the DEATH of an OH/IR star or its cyclical evolution back to a Mira variable. ...
