Resolved Companions of Cepheids: Testing the Candidates with X-Ray Observations

We have made {\it XMM-Newton\/} observations of 14 Galactic Cepheids that have candidate resolved (\(\geq\)5\(\arcsec\)) companion stars based on our earlier {\it HST\/} WFC3 imaging survey. Main-sequence stars that are young enough to be physical companions of Cepheids are expected to be strong X-r...
