    Chemical abundances of secondary stars in low mass X-ray binaries
    The high-velocity black hole in the low mass X-ray binary XTE J1118+480 could be the remnant of an massive star formed in the early stages of the evolution of...

    Chemical abundances of the H II regions NGC 5461 and NGC 5471 in M 101, derived from echelle spectrophotometry
    We present high resolution spectroscopic data of the two giant extragalactic HII regions NGC 5461 and NGC 5471 in M 101. We calculate the physical conditions in...
