Observation of radio flares of stars in the region of the Pleiades at 327 MHz.
Abstract
Results are reported for simultaneous optical and 327-MHz radio observations of stellar flares in the Pleiades. About 30 optical flares were observed, of which five occurred in the region covered by the directional diagram of the radio-telescope antenna. However, no significant enhancement of the radio signal above the radiometer noise level was detected in any of the five cases observed at 327 MHz. The radio and optical luminosities of the Pleiades stars near flare maximum are found to differ by no more than a factor of 5 to 10; it is concluded that there is no definite correlation between the energies and other parameters of stellar radio and optical flares. Five cases are discussed where flarelike signals of extraterrestrial origin were observed at 327 MHz from the Pleiades region at times when simultaneous optical observations were not made.
