Scientific paper

The scarce group of Oe stars are usually considered as the hot analogs of the Be-type objects. They should thus feature an equatorial decretion disk, possibly confined by a magnetic field. On theoretical grounds, such a magnetic field is expected to significantly affect the properties of the X-ray spectrum of the star. However, the existence of a disk has been questioned by recent optical spectropolarimetric observations and previous X-ray observations of two Oe stars (HD 155806 and HD 119682) revealed two very different behaviours. To help settle these issues, we propose to obtain XMM-Newton observations of two other Oe stars, HD 45314 and HD 60848 for 20 ksec each.
