... The width of hydrogen lines is known to depend on the pressure in the photosphere, and then on the luminosity and effective temperature of the star. We have studied this dependence using the spectra of normal B stars from the databases by Jacoby et al., ... The resolution of Jacoby spectra (4.5А) coincides with the resolution of our BTA/UAGS spectra (4.4A). ... Dependence of full width FWZI of hydrogen lines on star spectral type and luminosity class. ...

3) Planets and Brown Dwarfs . ... By its nature, this method is most sensitive to massive planets orbiting close to their stars. ... That means that some of the more massive extrasolar planets could actually be brown dwarfs (although the statistics of the finds suggest that most of them are not). ... Another possible difference between brown dwarfs and massive planets is how they are born. ... They would base the fundamental definition on the mode of formation: a planet is built from planetesimals. ...

... Though Flint knows the interface definitions (i.e. number, type and intent of each argument) of standard FORTRAN functions, it is desirable for users to build and use a file (or files) describing the interfaces to their own library. ... The format is: flint -o file .. ... While these interface definitions could be input along with normal source files, preceding the interface file with the -l (library) switch has the advantage that the source of this file does not appear in the listing file. ...
