We present a search for radio source counterparts of 508 main sequence stars, that are part of the target list of the Infra Red Space Interferometer DARWIN. We searched all available online radio surveys to find counterparts for DARWIN stars, and we only found 2 candidate identifications out of 508 in two surveys made with VLA radio telescope in New Mexico, USA. We required that candidate identifications should have fluxes larger than 3σ times the noise in the radio maps and have a radio-optical positional difference less than 15''. Both stars had radio counterparts in NVSS (NRAO VLA Sky Survey) and one of them also in FIRST (Faint Images of the Radio Sky at Twenty-centimeters). Both surveys are 1.4 GHz continuum surveys. Our goal for this project is to show that there are main sequence stars whose radio emission is detectable and get a statistical limit for the radio flux of the DARWIN stars. The method we performed was to use the radio maps and coadd these maps at the location of the stars.
