dc.description.abstractOur 35 ksec ROSAT HRI observation of M33 reveals 37 X‐ray sources stronger than about 2.3σ. Eight of the sources are coincident with supernova remnants, four are coincident with giant HII regions, and three are coincident with HI holes. M33 X‐7 is a compact accreting eclipsing binary, similar to binary X‐ray sources detected in the Galaxy. Our ROSAT data confirm the binary interpretation and allow us to measure the period to an accuracy of 0.001%. The nuclear source, M33 X‐8, is not found to be variable in the ROSAT HRI observations, although it varied as much as 40% between Einstein HRI observations. © 1994 American Institute of Physicsen_US
