In this section, we study the evolution of stellar populations on a time-scale of 10 Myr for a starburst љ occurring under conditions similar to those in the Galactic Center (see Lipunov et al. (1995d)[ 126 ]). We estimate the expected number of X-ray transient љ sources (NS + MS star), super accreting BH, and BH + supergiant binaries, all as functions of time elapsed after the burst. ...

... The absolute magnitude of the RCBs in the LMC and the small number of Galactic RCBs implies that they are very rare stars. Together with statistics for related stars, the total number of hydrogen-deficient stars in the Galaxy is estimated to be about 1000. Whilst the luminosity of RCBs is similar to that of other low-mass stars as they evolve rapidly from the asymptotic RED GIANT branch to become WHITE DWARFS , their frequency is much lower. ...

Session 9 - The Hubble Deep Field. ... The Hubble Deep Field (HDF) experiment is a unique project to explore at unprecedented depth and angular resolution the faintest and most distant galaxies. ... This allows study of broad-band spectral energy distribution, morphology and number count statistics for galaxies that span the largest, if not the whole, time interval of galaxy history. ... Here we present preliminary number counts, color-magnitude and color-color diagrams for the 4 HDF frames. ...

... Your main research interests lie in starburst galaxies. ... Perhaps it is the howling wind and lack of insulation in your offices that does it, but the glowing warmth of a galaxy violently forming vast numbers of stars has a great attraction to you. ... All the nearby galaxies that are forming stars at reasonable rates are very dusty: most of the radiation from their young stars and supernovae is absorbed by dust and re-radiated in the far-IR. ...
