Query: NGC 1535: UV Observations and Models   We reinvestigate the UV spectrum of NGC1535 by means of recently developed
fully line-blanketed non-LTE models. These new models account for the wind in
spherical geometry while handling the atomic data in a very similar way to the
TLUSTY code. This approach ensures at the same time realistic predictions of
the photospheric absorption lines and of the emission lines formed in the wind.
Our analysis confirms the results of previous studies. We derive T_* = 70kK,
log M_dot = -7.8M_sun/year and v_infty = 2000km/s.
