A search for slowly varying radio continuum emission from UV Ceti stars

The paper presents results of a search conducted at the Arecibo Observatory for variable 430-MHz emission from the active flare stars EQ Peg, YZ CMi, and AD Leo. No statistically significant evidence for slowly varying emission is found to a level of 0.05 Jy for AD Leo, 0.018-0.021 Jy for YZ CMi, and 0.009-0.018 Jy for EQ Peg. Upper limits of about 10 trillion K are determined for the brightness temperature of active radio regions on these stars at the time of the observations.
