The periodic variations in the flux of the object Geminga in the gamma and X-ray ranges are interpreted as the orbital revolution of a degenerate dwarf with M = 0.6 solar mass around a black hole with total mass of the system M = 5 solar masses. It is assumed that the dwarf fills it Roche lobe, its orbital period is equal to the observed 1 min, and gravitational radiation together with mass transfer explain the increase in the period. It is assumed that other unidentified galactic gamma point sources belong to the same class of object. In the model proposed, the energy flux of the gravitational waves from Geminga at the earth is 0. 0005 erg/sq cm/sec for the distance 100 pc; this is at the limit of modern observational possibilities.
