Radial solitary waves in periodic variable stars
Fedor V. Prigara
It is shown that the oscillations of brightness in classical Cepheids and other 'pulsating' variable stars are caused rather by the passing of radial solitary waves through the pho…
Radiation-induced solitary waves in hot plasmas of accretion disks
Fedor V. Prigara
It is shown that the existence of radiation-induced solitary waves in hot plasmas of accretion disks depends on the radial temperature profile.
The energy distribution of atoms in the field of thermal radiation
F. V. Prigara
Using the principle of detailed balance and the assumption on the absorption cross-section consistent with available astrophysical data, we obtain the energy distribution of atoms…
Einstein's coefficients and the nature of thermal blackbody radiation
F. V. Prigara
We show that thermal radio emission has an induced character and argue that thermal blackbody radiation in other spectral ranges also has an induced origin. A new theory of thermal…

Thermal Radio Emission as Incoherent Induced Radiation
Fedor V. Prigara
The synchrotron interpretation of radio emission from various astrophysical objects encounters the essential difficulties . These difficulties may be overcome in a new theory of th…
Einstein's coefficients and the nature of thermal radio emission
F. V. Prigara
The relations between Einstein's coefficients for spontaneous and induced emission of radiation with account for the natural linewidth are obtained . It is shown that thermal radio…
Thermal radio emission : The brightness temperature and the spectral index of radio emission
F. V. Prigara
The condition of radio emission is proposed, on the base of which the theory of themal radio emission for gaseous disk is developed. This theory explains the radio emission spectra…
