All 24 stars have parallaxes accurate to better than 3 X sigma and have RUWE values less than 1.4. Based on the Gaia DR3 distances the absolute luminosities are derived. For 14 of the stars, the luminosities confirm their post-AGB evolutionary stage. However, V1027 Cyg, which was previously classified as a post-AGB star, is found to have a higher luminosity; thus it may be an evolved, massive, pulsating semi-regular variable star of type G7Ia. For 9 of the stars, the luminosities are lower than 1000 L (sun), indicating that some are post-RGB stars and some are post-HB stars.This paper was completed more than four months ago but there was delay in getting it published.", "revisions": [ { "version": "v1", "updated": "2022-09-30T14:58:30.000Z" } ], "analyses": { "keywords": [ "gaia dr3 data", "selected post-agb stars", "evolutionary status", "luminosity", "post-agb evolutionary stage" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
