资源简介：
The eROSITA collaboration has completed eFEDS a 140 sq deg survey to the finalall-sky depth with almost complete optical identification of the X-ray sourcecontent. Three new AM CVn objects were discovered two of which have Gaiadistances. AM CVn are ultracompact white-dwarf accreting binaries withdegenerate Roche-lobe filling donors. We propose a combined XMM-Newton and VLTstudy of the two objects with Gaia astrometry to perform a timing and spectralstudy. We want to measure their orbital periods determine their accretionluminosity establish the abundancies and thus constrain their evolutionaryhistory and status. [truncated!
