New results on LS I +61 ° 303 and Cygnus X-3

Abstract

We present here preliminary results of 6 cm VLBI and VLA observations of LS I +61 ° 303 as well as 3.6 cm VLA observations of Cyg X-3. An interesting finding consists of the detection of small amplitude radio flares in the normal VLA interferometer data of LS I +61 ° 303, with an apparent recurrence period of 1.4 h. In addition, the VLA observations of Cyg X-3 exhibit some evidence of possible arcsecond radio jets in this source.
