Abstract
A brief review is given of the results of the new method to study astrophysical objects by spectral-time analysis (STA) of their electromagnetic radiation (IMR) envelope. Fundamentally new data have recently been obtained in solar-stellar astronomy. We have detected solar microwave radiation pulsations identified with different oscillations in flare coronal magnetic loops (CMLs): magnetosonic waves, kink modes, and eigenoscillations of loop currents (LCR) in energy accumulation and release processes. Oscillations have been investigated in inductively coupled current-carrying CMLs. The acoustic 5-min photospheric wave parametric resonance in a CML has been detected which is thought to be a new channel for the photosphere energy absorption and subsequent corona heating. The existence has been established of the flare CMLs similar to the solar ones in the atmosphere of the star AD Leo. The effectiveness of the STA method of IMR envelope has been proved for the study of planetary transit curves and stellar seismology (using CoRoT satellite data).
