cds-question@unistra.fropen-star-clustersvisible-astronomybroad-band-photometryinfrared-photometryproper-motionsradial-velocityOn the basis of the PPMXL catalogue we perform an all-sky census of the Hyades down to masses of about 0.2M_{sun}_ in a region up to 30pc from the cluster centre. We use the proper motions from PPMXL in the convergent point method to determine probable kinematic members. From 2MASS photometry and CMC14 r'-band photometry, we derive empirical colour-absolute magnitude diagrams and, finally, determine photometric membership for all kinematic candidates. This is the first deep (r'<17) all-sky survey of the Hyades allowing a full three-dimensional analysis of the cluster. The survey is complete down to at least M_{K_s_}_=7.3 or 0.25M_{sun}_. We find 724 stellar systems co-moving with the bulk Hyades space velocity, which represent a total mass of 435M_{sun}_. The tidal radius is about 9pc, and 275M_{sun}_ (364 systems) are gravitationally bound. This is the cluster proper. Its mass density profile is perfectly fitted by a Plummer model with a central density of 2.21M_{sun}_/pc^3^ and a core radius of r_co_=3.10pc, while the half-mass radius is r_h_=4.1pc. There are another 100M_{sun}_ in a volume between one and two tidal radii (halo), and another 60M_{sun}_ up to a distance of 30pc from the centre. Strong mass segregation is inherent in the cluster. The present-day luminosity and mass functions are noticeably different in various parts of the cluster (core, corona, halo, and co-movers). They are strongly evolved compared to presently favoured initial mass functions. The analysis of the velocity dispersion of the cluster shows that about 20% of its members must be binaries. As a by-product, we find that presently available theoretical isochrones are not able to adequately describe the near-infrared colour-absolute magnitude relation for those cluster stars that are less massive than about 0.6M_{sun}_.2011A&A...531A..92Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/531/A92CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/317 : The PPMXL Catalog (Roeser+ 2010)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)I/280 : All-sky Compiled Catalogue of 2.5 million stars (Kharchenko+ 2009)I/304 : Carlsberg Meridian Catalog 14 (CMC14) (CMC, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/531/A92https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/531/A92http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/531/A92https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/531/A92https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/531/A92http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/531/A92GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/531/A92/table1 (Data of 724 Hyades candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/531/A92/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/531/A92/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/531/A92/table1?GETtext/xml+votable180.050000true28.3364223.44476250.0055555555555555565/80-81 84 87 256 261-262 5869 5874-5875 5878 5880-5881 5883-5884 5886-5887 6050 6052 6058-6059 6/60 75 78 95 100 107 125 197 211 247 272-274 276 278 287 305 309 311 313 318 330 333-335 340-342 344-345 353 355 357-358 365 367-370 373 375 378-379 381 383 401 407 422 438 450 456 458 462 465 470 472 475 477-478 483 499 501 507 528 540 583 608 671 701 706 711-712 729 766 770 780 795 803 820 823 835 837 840 847 879 882 889-890 917 924 959 989 997 1009 1020 1029 1031-1033 1035-1038 1041-1043 1052 1057-1058 1060-1062 1064-1065 1075 1077 1094 1096-1097 1113 1127 1146 1158-1159 1167 1180 1196 1198-1199 1206 1210-1211 1232 1234 1239 1272 1324 1342 1415 1451 1554 1564 1567 1577 1602 1609 1611 1614 1661 1676 1713 1720 1752 1817 1827 1839 2139 2328 2335 2350 2375 2383 2391 17714 17857 17871 21156 21196 21221 21235 21275 21383 21391 21418 21440 21496 22558 22566 22598 22628 22663 22713 22760 22769 22781 22811 22823 22827 22830 22837 22847 22882 22884 22892 22902 22904 22906-22907 22911 22916 22920 22949 22959 22970 22978 23011 23017 23022-23024 23026 23029 23035 23111 23140 23169 23256 23261 23276 23282-23283 23286 23288 23313 23315 23321 23324 23328-23329 23332 23335 23339 23344 23348 23355 23358-23359 23362 23364 23368-23370 23374-23375 23378 23383 23386-23387 23392 23395-23396 23399-23400 23403 23405-23406 23408 23410 23413 23415-23416 23418-23419 23421 23423 23437 23440 23443-23444 23450 23453-23454 23463 23484 23487 23489-23494 23504-23505 23507-23509 23511 23517-23519 23529-23531 23540-23542 23597 23663 23680 23694 23704 23721-23722 23727 23738 23741 23748 23789 23794 24067-24068 24070 24075 24078 24097 24099 24102 24104 24106 24110 24114 24123-24124 24126 24129 24137 24162 24175 24192 24194-24196 24204 24206-24207 24212 24215-24216 24218-24220 24223-24226 24228-24230 24241-24242 24244 24246 24248-24249 24251-24252 24256 24266 24298 24310 24315 24319 24336 24344 24359-24360 24363 24382 24470 24482 24491 24502 24506 24552 24554 367588.650015785639275e-20 4.920466254354166e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/531/A92?format=asciiInfraredOpticaldefaultJ/A+A/531/A92/table1Data of 724 Hyades candidatesrecnoRecord number assigned by the VizieR team.
