Galactic Miras with light-curve asymmetries J/A+A/700/A187 ivo://CDS.VizieR/J/A+A/700/A187 doi:10.26093/cds/vizier/bc-nw/lbih CDS Uttenthaler S. Merchan-Benitez P. 2026-08-03T06:56:21Z 2025-08-22T08:21:38Z CDS support team CDS, Observatoire de Strasbourg, 11 rue de l'Universite, F-67000 Strasbourg, France cds-question@unistra.fr variable-stars stellar-spectral-types infrared-astronomy In a recent publication, we established a close relationship between light-curve asymmetries in Mira variables and indicators of their dust mass-loss rate. The light-curve asymmetries appear to be related to the stars' third dredge-up (3DUP) activity. We aim to reveal the evolutionary status of M-type Miras with light-curve asymmetries ("bumps") within the spectral sequence M-S-C, determine their mass-loss properties, and check possible evolutionary scenarios. We analysed a sample of 3100 Miras collected from the ASAS database, distinguishing between symmetric and asymmetric light curves. We determined their periods, luminosity functions, and period-luminosity relations, their locations relative to the Galactic midplane, as well as mass-loss rate indicators through the 2MASS-WISE colours and the Gaia-2MASS diagram. The M-type Miras with symmetric light curves are generally found to have shorter periods, lower luminosities, a larger average distance to the Galactic midplane, and lower initial mass than the M-type Miras with asymmetries. In addition, 25 Miras are proposed as candidates for new carbon stars. We propose that the M-type Miras have two distinct populations: M-type Miras with symmetric light curves, which have lower initial mass progenitors than M-type Miras with asymmetries, which show signs of 3DUP activity and are the link to the S-type Miras. 2025A&A...700A.187U https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/700/A187 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to J/A+A/672/A165 : Meandering-period Miras (Merchan-Benitez+, 2023) https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/700/A187 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/700/A187 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/700/A187 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/700/A187 https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/700/A187 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/700/A187 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/A+A/700/A187/table (Results of the new analysis of Mira light curves in this paper) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/700/A187/table? https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/700/A187/table? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/700/A187/table?
