The eROSITA telescope on board the Spektr-RG mission is conducting an all-sky X-ray survey and recently released the public eROSITA Final Equatorial Depth Survey (eFEDS) catalog. We crossmatched the eFEDS catalog with photometry from the Zwicky Transient Facility and discovered two new magnetic CVs. We obtained high-cadence optical photometry and phase-resolved spectroscopy for each magnetic CV candidate and found them both to be polars. Among the newly discovered magnetic CVs is eFEDS J085037.2+044359/ZTFJ0850+0443, an eclipsing polar with orbital period Porb = 1.72 hr and WD mass MWD = 0.81 ± 0.08M⊙. We suggest that eFEDS J085037.2+044359/ZTFJ0850+0443 is a low magnetic field strength polar, with BWD ≲ 10 MG. We also discovered a non-eclipsing polar, eFEDS J092614.1+010558/ZTFJ0926+0105, with orbital period Porb = 1.47 hr and magnetic field strength BWD = 36–42 MG.","lang":"eng"}],"status":"public","date_created":"2024-03-26T09:48:51Z","article_number":"141","oa_version":"Published Version","quality_controlled":"1","tmp":{"image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"external_id":{"arxiv":["2206.04714"]},"publisher":"American Astronomical Society","extern":"1","date_published":"2023-03-15T00:00:00Z","license":"https://creativecommons.org/licenses/by/4.0/","_id":"15200","main_file_link":[{"url":"https://doi.org/10.3847/1538-4357/acbb6f","open_access":"1"}],"doi":"10.3847/1538-4357/acbb6f","oa":1}
