The Kurucz program suite is a standard tool for modelling photospheres and generating synthetic spectra. It has the advantages of being very well-tested, reliable, and useful for a wide range of stellar physical parameters (Teff , log g, [Z/Z ]). Here we improve on the original Kurucz assumption that even a fast-rotating star is considered to be of spherical shape, thus making possible to separately determine both components of the projected rotational velocity v sin i; we also explore the advantages of porting the code to run it on an Intel-PC under Linux.
