Light-time effect in eclipsing binaries.
WOLF M.
Abstract (from CDS):
The role of the light-time effect in stellar studies is briefly discussed. Base on the list of published photoelectric minima, the new parameters of the third body's orbit for two well-known eclipsing binaries, TW Dra and TX Her, are derived. For each system the minimum mass of a third component is computed.
