Radio Emission from Algol
We report dual circular polarization VLBA observations of Algol made at orbital phases 0.22{0.30 using a diierential phase referencing technique. The ux density of Algol varied from 10{20 mJy during the observations. The radio maps show a double-lobe source separated by 1.6 mas (1.4 times the K star diameter). Although the total emission is only weakly circularly polarized, the individual lobes...
متن کاملRadio emission from Algol-type binaries I. Results of 1992-1993 VLA survey
In this paper we report on a 5 GHz survey of 26 Algol-type binaries. Six systems were detected. We combine the new results with previously published data to derive some radio characteristics of Algols and to compare them with those of other active binaries. The radio detection rate of 30 %, a factor that is somewhat smaller compared to the case ofRSCVntype, does not seem to be due to a reduced ...
متن کاملThe structure of Algol ’ s corona : a consistent scenario for the X - ray and radio emission
We present a systematic analysis of the four known large X-ray flares detected to date on the eclipsing binary system Algol, using an approach based on hydrodynamic simulations of decaying flaring loops including sustained heating. This method yields, for the large BeppoSAX Algol flare of Aug. 1997 (where a geometrical estimate of the size of the flaring region is available) a more reliable siz...
متن کاملRadio Emission from Exoplanets
We present results from new low frequency observations of two extrasolar planetary systems (ε Eridani and HD128311) taken at 150 MHz with the Giant Metrewave Radio Telescope (GMRT). We do not detect either system, but are able to place tight upper limits on their low frequency radio emission.
متن کاملRadio Emission from Jupiter
Three reviews of radio emission from Jupiter have appeared recently (1, 2, 3) and at least one more is currently in press. The present review primarily covers work since 1961. It would be not too strong to suggest that explanations of Jupiter's emission now are in the second generation, with most observational phenomena fairly well established. The salient observed features are not widely known...
