    Notes: [Auszug] The object F-71 (a1950 = 20h 14.8 min, ?1950 =-57 43') from FairalFs list3 of compact galaxies appears as an almost circular galaxy of approximate magnitude 16 mag on the European Southern Observatory (ESO) Quick Blue Survey plate. Towards the north-east of the object a starlike companion is ...

    Spectroscopic evolutionary synthesis models of Wolf-Rayet galaxies (1993)
    Springer

    Notes: Abstract We present spectroscopic evolutionary synthesis calculations for starburst galaxies of various metallicities in order to model the broad emission lines HeII λ4686 and CIII λ4650 produced by Wolf-Rayet (WR) stars in the spectra of WR galaxies. The strengths of both lines strongly decrease with decreasing metallicity. The presence of WR emission features is a clear indicator of very recent star formation less than 4 to 7 × 106 yr ago. Bursts of duration 1 to 5 × 106 yr which lead to an increase in the total stellar mass in the galaxy by 0.1 to 10 % are compatible with the equivalent width of Hell »4686 observed in WR galaxies.
