Abstract:
Outline of a project aimed at testing the presence of rapid
line-profile variations in the atmospheres of hot components of close
binaries is presented and its first results are described. An analysis
of new electronic spectra of the eclipsing binary V436 Per from three
observatories and of photoelectric observations, obtained earlier by
several authors, leads to a unique determination of all basic physical
elements of this interesting object. The first practical application
of a new method of spectral disentangling allowed us to obtain, for
the first time, individual accurate line profiles of both binary
components and to derive their rotational velocities and orbital
radial-velocity curves. We also detected absorption sub-features
travelling from blue to red accross the He I 6678 line profile, in a
series of six spectra taken during one night. At least one of the
components of V436 Per is, therefore, a new hot line-profile variable.
