cds-question@unistra.frgiant-starsasteroseismologyspectroscopyOscillation modes of a mixed character are able to probe the inner region of evolved low-mass stars and offer access to a range of information, in particular, the mean core rotation. Ensemble asteroseismology observations are then able to provide clear views on the transfer of angular momentum when stars evolve as red giants. Previous catalogs of core rotation rates in evolved low-mass stars have focussed on hydrogen-shell burning stars. Our aim is to complete the compilation of rotation measurements toward more evolved stages, with a detailed analysis of the mean core rotation in core-helium burning giants. The asymptotic expansion for dipole mixed modes allows us to fit oscillation spectra of red clump stars and derive their core rotation rates. We used a range of prior seismic analyses, complete with new data, to get statistically significant results. We measured the mean core rotation rates for more than 1500 red clump stars. We find that the evolution of the core rotation rate in core-helium-burning stars scales with the inverse square of the stellar radius, with a small dependence on mass. Assuming the conservation of the global angular momentum, a simple model allows us to infer that the mean core rotation and envelope rotation are necessarily coupled. The coupling mechanism ensures that the differential rotation in core-helium-burning red giants is locked.2024A&A...681L..20Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/681/L20CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/133 : Kepler Input Catalog (Kepler Mission Team, 2009)J/A+A/588/A87 : Seismic global parameters of 6111 KIC (Vrard+, 2016)J/A+A/600/A1 : Coupling factors of 5166 KIC (Mosser+, 2017)J/A+A/618/A109 : Seismic global parameters of 372 KIC (Mosser+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/681/L20https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/681/L20http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/681/L20https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/681/L20https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/681/L20http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/681/L20GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/681/L20/table1 (Seismic global parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/681/L20/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/681/L20/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/681/L20/table1?GETtext/xml+votable180.050000true291.056163636.70401690.0055555555555555564/923 933 5/3645-3647 3683 3688-3690 3704 3706 3730-3731 3736 3741-3743 3776 3778-3780 3782-3783 3785 3788 3792 6/14559 14567 14573 14575 14577-14579 14730-14731 14744 14746 14750-14751 14764-14765 14767 14792 14794 14822 14828 14830 14914-14915 14917-14919 14948 14950 14952-14953 14955 14957-14962 15040-15041 15044-15045 15057 15059-15062 15108-15110 15124 15126-15127 15136-15137 15139 15145-15150 15156 15158-15160 15172-15174 15200https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/681/L20?format=asciidefaultJ/A+A/681/L20/table1Seismic global parametersSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
