cds-question@unistra.frdwarf-starsm-starsvisible-astronomyStellar rotation is closely linked to both the age and the magnetic activity of stars. Through gyrochronology, it provides a means to estimate stellar ages and trace the evolution of planetary systems, and it is also crucial to constrain and correct stellar activity effects for robust exoplanet detection and characterisation. CARMENES is a dual-channel, high-resolution (R>80000) spectrograph that has been highly successful in detecting exoplanets around M-dwarf stars using the radial-velocity technique, and it also enables precise measurements of the projected rotational velocity (vsini) from spectral line broadening. We present an oversampled convolution method incorporating a realistic limb-darkening model to determine vsini from CARMENES spectra by comparing observed spectra with that of a template star. The advantages over existing methods in the literature have been assessed using high-resolution synthetic spectra spanning effective temperatures of 2500-4000K and projected rotational velocities of up to 50km/s. Applied to 392 M dwarfs observed with CARMENES, our method yields vsini measurements (or upper limits at 2km/s) with a median relative uncertainty of 6.8%, substantially smaller than the 15.4% reported in the literature. This work provides the largest uniform catalog of vsini measurements for M dwarfs, including significantly updated values for several targets, along with 36 new targets.2026A&A...709A.244Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/709/A244CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/709/A244https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/709/A244http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/709/A244https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/709/A244https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/709/A244http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/709/A244GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/709/A244/table2 (Catalogue of vsini of the CARMENES VIS M dwarf sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/709/A244/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/709/A244/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/709/A244/table2?GETtext/xml+votable180.050000true1.295371745.78656690.0055555555555555566/22 105 131 239 250 497 527 546 624 725 778 811 865 1033 1357 1628 1672 1712 1793 1822 1875 1938 2190 2435 2515 2545 2681 2737 2747 2922 3031 3035 3266 3309 3345 3374 3658 3682 3715 3791 3900 4033 4145 4366 4444 4518 4595 4651 4867 5000 5009 5041 5207 5212 5241 5343 5354 5420 5488 5534 5590 5601 5610 5657 5727 5842 5849 6384 6552 6672 6676 6809 6894 6980 7003 7103 7181 7262 7264 7395 7428 7471 7510 7605 7611 7625 7775 7837 7921 7937 7940 7980 7984 8023 8032 8123 8163 8208 8240 8281 8331 8394 8562 8588 8617 8627 8733 8843 8915 9188 9471 9529 9578 9597 9750 10037 10149 10225 10278 10448 10464-10465 10694-10695 10901 10999 11044 11177 11255 11403 11459 11636 11671 11923 11962 11974 12128 12140 12184 12191 12621 12732 12865 12999 13085 13427 13451 13567 13688 13743 13875 13912 14277 14395 14515 14709 14781 14850 14858 14985 14993-14994 15052 15078 15311 15346 15355 15431 15548 15598 15602 15629 15635 15748 15763 15792 15866 15960 16041 16092 16117 16266 16754 16758 17020 17271 17302 17348 17358 17412 17606 17748 17870 18195 18268 18364 18440 18496 18553 18666 18726 18761 18789 18942 19050 19064 19131 19306 19352 19466 19516 19791 19879 20023 20100 20109 20311 20459 20472 20795 20839 20896 21051 21151 21171 21427 21647 21747-21748 21953 21969 21986 22014 22222 22277 22289 22309 22559 22626 22645 22661 22709 22807 22904 22942 23014 23094 23293 23363 23453 23564 23718 23731 23735 23743 23867 23910 23997 24213 24227 24231 24239 24356 24977 24995 25009 25363 25388 25512 25528 25792 25849 25989 26063 26327 26487 26538 26560 26563 26583 26699 26706 26731 26757 26768 26772 26821 26972 27201 27289 27320 27392 27419 27459 27462 27730 27734 27762 27787 27820 27912 28223 28279 28341 28343 28548 28646 28955 29146 29170 29458 29684 29764 30011 30429 30455 30490 30505 30613 30771 30833 30893 31014 31019 31191 31229 31642 31686 31767 31781 31803 31811 31983 32033 32076 32093 32115 32329 32335 32392 32458 32491 32541 32730 32753 36643 36732 40250 40275 40359 40386 40435-40436 40505 40513 40610 40623 40772 40941 44518 44541 44696 44728 44921 44936-44937 44967 48274 48485 48500 48801 48906 48935 48958 49101https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/709/A244?format=asciiOpticaldefaultJ/A+A/709/A244/table2Catalogue of vsini of the CARMENES VIS M dwarf samplerecnoRecord number assigned by the VizieR team.
