Centimeter observations of six eclipsing 'Serpentid' binary stars

Centimeter observations of the following eclipsing 'Serpentid' binary stars have been performed: SY And, RX Cas, SX Cas, V367 Cyg, RZ Sct, and W Ser. RZ Sct and W Ser were detected at 3.6 cm, and V367 Cyg was detected at both 6 and 3.6 cm. It is suggested that these objects emit thermalized-gyrosynchrotron radiation as does Beta Lyr but at much lower levels, because the circumstellar environments are different. 31 refs
