We model the CE as a fast stripping phase in which the primary experiences rapid mass loss and loses about 80 per cent of its mass. The post-CE remnant is then allowed to thermally readjust during a Roche-lobe overflow (RLOF) phase and the final binary system and its orbital period are investigated. We find that the post-CE RLOF phase is long enough to allow nuclear burning to proceed in the helium shell. By the end of this phase, the donor is stripped of both its hydrogen and helium and ends up as carbon-oxygen white dwarf of mass about $0.8\,\rm M_{\odot}$. We study the sensitivity of our results to initial conditions of different companion masses and orbital separations at which the stripping phase begins. We find that the companion mass affects the final binary separation and that helium-shell burning causes the star to refill its Roche lobe leading to post-CE RLOF. Our results show that double mass transfer in such a binary interaction is able to strip the helium and hydrogen layers from the donor star without the need for any special conditions or fine tuning of the binary parameters. dc.publisher Oxford University Press (OUP) dc.title Post-common envelope binary systems experiencing helium-shell-driven stable mass transfer dc.type Article prism.endingPage 5183 prism.issueIdentifier 4 prism.publicationDate 2018 prism.publicationName Monthly Notices of the Royal Astronomical Society prism.startingPage 5176 prism.volume 480 dc.identifier.doi 10.17863/CAM.35172 dcterms.dateAccepted 2018-08-10 rioxxterms.versionofrecord 10.1093/mnras/sty2243 rioxxterms.version VoR rioxxterms.licenseref.uri http://www.rioxx.net/licenses/all-rights-reserved rioxxterms.licenseref.startdate 2018-01-01 dc.contributor.orcid Izzard, Robert [0000-0003-0378-4843] dc.contributor.orcid Tout, Christopher [0000-0002-1556-9449] dc.identifier.eissn 1365-2966 dc.publisher.url http://dx.doi.org/10.1093/mnras/sty2243 rioxxterms.type Journal Article/Review pubs.funder-project-id Science and Technology Facilities Council (ST/M003892/1) cam.issuedOnline 2018-08-16 cam.orpheus.success Thu Jan 30 10:52:26 GMT 2020 - The item has an open VoR version. rioxxterms.freetoread.startdate 2100-01-01
