... We consider stars with a constant (solar) initial chemical composition. Before the Roche lobe overflow, the components evolve as single stars (see for details LPP96). ... If the mass transfer onto a normal star occurs on a time-scale ten time shorter than the thermal Kelvin-Helmholz time for this star or a compact star is engulfed by a giant companion (e.g. as a result of the kick), the common envelope (CE) stage of the binary evolution is set in (Paczynski 1976). ...

... SFIT is a general-purpose code designed to optimize theoretical stellar spectra to an observed spectrum. ... While the programme expects input from "stdio", it is more natural to save commands in a file (eg "sfit_input") and run the code simply by . ... If the spectra to be fitted have a filename "star_spectrum", then the best fit spectrum will be written out, together with the renormalized input spectrum, to a file called "star_spectrum.fit". ... sets up model spectrum grid (and for 2nd star) . ...

Next: Feature enhancement: local Up: No Title Previous: Feature enhancement: filtering . ... As a result, a common magnitude scale (contour lines on the maps above, or color scale on Fig.1) will poorly display the short-duration events in a signal. Normalizing each line of the map (fixed duration) so it has unit variance (in effect dividing the energy map by the mean energy spectrum) at each duration restores more details of small-scale activity (Fig. ...
