THE existence of a number of radio sources with an angular extension less than 1'' is well known1. Some of them were identified with star-like objects and therefore they are referred to as radio stars. Among these are 3C-48, 3C-119, 3C-147, 3C-273, 3C-286. Their non-thermal spectra and the evidence of a rather strong linear polarization suggest the synchrotron mechanism of radio emission. Twiss2, Razin3, and Le Roux4 have shown that a self-absorption of synchrotron radiation by relativistic electrons must occur at frequencies f < f1, f1 depending on relativistic electrons concentration, normal component of magnetic field H⊥, spectral index of radio emission α (the spectrum being of the form S(f) ~ f-a), and on linear dimension of radio-emitting region. At frequencies below f1 the spectrum of radio emission is S(f) ~ f2.5 whatever α is, thus f1 is a frequency where maximum flux density of a radio source occurs.
