We propose to study within a well selected sample of compact starbursts therelation between the X-ray luminosity and the star formation rate (SFR).Comparing the hard X-ray data to optical emission line, FIR and radio data - allindicators of the current SFR - we intend to confirm and calibrate the apparentempirical relation between X-ray luminosity and SFR. Our sample of HII galaxiesis ideal for this task: there is excellent supporting data for independentmeasures of the SFR and, importantly, the hard X-ray emission of these low mass,high SFR systems will be dominated by SFR-tracing High Mass X-ray Binaries. Theapplications of hard X-rays as a largely absorption independent SFR tracerjustify further analysis with high quality data such as that proposed here.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
