cds-question@unistra.frasteroseismologylate-type-starsvariable-starseffective-temperaturevisible-astronomytrigonometric-parallaxWhile long-period variables (LPVs) have been extensively investigated, especially with MACHO and OGLE data for the Magellanic Clouds, there still exist open questions in their pulsations regarding the excitation mechanisms, radial order, and angular degree assignment. Here, we perform asteroseismic analyses on LPVs observed by the 4-year Kepler mission. Using a cross-correlation method, we detect unambiguous pulsation ridges associated with radial fundamental modes (n=1) and overtones (n>=2), where the radial order assignment is made using theoretical frequencies and observed frequencies. Our results confirm that the amplitude variability seen in semiregulars is consistent with oscillations being solar-like. We identify that the dipole modes, l=1, are dominant in the radial orders of 3=<n=<6, and that quadrupole modes, l=2, are dominant in the first overtone n=2. A test of seismic scaling relations using Gaia DR2 parallaxes reveals the possibility that the relations break down when {nu}_max_~<3{mu}Hz (R>~40R_{sun}_, or logL/L_{sun}_>~2.6). Our homogeneous measurements of pulsation amplitude and period for 3213 LPVs will be valuable for probing effects of pulsation on mass-loss, in particular in those stars with periods around 60d, which has been argued as a threshold of substantial pulsation-triggered mass-loss.2020MNRAS.493.1388Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/493/1388CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/133 : Kepler Input Catalog (Kepler Mission Team, 2009)I/345 : Gaia DR2 (Gaia Collaboration, 2018)J/ApJS/229/30 : Revised stellar properties of Q1-17 Kepler targetshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/493/1388https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/493/1388http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/493/1388https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/493/1388https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/493/1388http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/493/1388GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/493/1388/table1 (Asteroseismic parameters and stellar properties of Kepler M giants)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/493/1388/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/493/1388/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/493/1388/table1?GETtext/xml+votable180.050000true291.1452936.694080.0055555555555555564/922-923 933-935 944-946 5/3645-3647 3683 3704 3706 3729-3731 3760 3789 3792 6/14567 14573 14575 14577-14579 14730-14731 14738 14744 14746 14749-14751 14792 14794-14795 14828 14830 14914-14915 15044-15045 15057 15059-15062 15153-15155 15160 15172-15174 15176 15178 15200 15232https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/493/1388?format=asciiOpticaldefaultJ/MNRAS/493/1388/table1Asteroseismic parameters and stellar properties of Kepler M giantsSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
