cds-question@unistra.freclipsing-binary-starsplanetary-nebulaeccd-photometryWe present a study of Hen 2-155 and Hen 2-161, two planetary nebulae which bear striking morphological similarities to other planetary nebulae known to host close-binary central stars. Both central stars are revealed to be photometric variables while spectroscopic observations confirm that Hen 2-155 is host to a double-eclipsing, post-common-envelope system with an orbital period of 3h 33m making it one of the shortest period binary central stars known. The observations of Hen 2-161 are found to be consistent with a post-common-envelope binary of period ~1-day.2015A&A...580A..19Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/580/A19CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/580/A19https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/580/A19http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/580/A19https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/580/A19https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/580/A19http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/580/A19GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/580/A19/table3I-band photometry of central star of Hen 2-161 (table 3)recnoRecord number assigned by the VizieR team.
