cds-question@unistra.frDoppler Imaging produces 2D global maps of rotating objects using high-dispersion spectroscopy. When applied to brown dwarfs and extrasolar planets, this technique can constrain global atmospheric dynamics and/or magnetic effects on these objects in un- precedented detail. I present the first quantitative assessment of the prospects for Doppler Imaging of substellar objects with current facilities and with future giant ground-based telescopes. Observations will have the greatest sensitivity in K band, but the H and L bands will also be useful for these purposes. To assess the number and availability of targets, I also present a compilation of all measurements of photometric variability, rotation period (P), and projected rotational velocity (vsini) for brown dwarfs and exoplanets. Several bright objects are already accessible to Doppler Imaging with currently available instruments. With the development of giant ground-based telescopes, Doppler Imaging will become feasible for many dozens of brown dwarfs and for the few brightest directly imaged extrasolar planets (such as beta Pic b). The present set of measurements of P, vsini, and variability are incomplete for many objects, and the sample is strongly biased toward early-type objects (<L5). Thus, surveys to measure these quantities for later-type objects will be especially helpful in expanding the sample of candidates for global weather monitoring via Doppler Imaging.2014A&A...566A.130Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/566/A130CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/PAZh/27/403 : CCD R photometry in the UMa supercluster (Kopylova+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/566/A130https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/566/A130http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/566/A130https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/566/A130https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/566/A130http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/566/A130GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/566/A130/rotation (Variability and rotation measurements)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/566/A130/rotation?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/566/A130/rotation?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/566/A130/rotation?GETtext/xml+votable180.050000true258.7179166730.328055560.0055555555555555566/221 223 342 360 399 463 483 487-488 496 619 826 1031 1050 1054 1073-1075 1159 1168 1539 2101 2110 2149 2202 2784 2978 3965 4436 4486 4515 4645 4698 4719 4768 4775 5077 5264 5317 5429 5540 5560 5854 6261 6328 7440 7533 8361 8381 8402 8440 8478 8719 8735 8761 8794 8874 8972 8995 9009 9039 9146 9387 9449 9472 9569 9588 9677 9779 9880 10332 10753 10850 11028 11596 11639 11719 11856 12600 13336 13425 13530 13559 13736 14858 14910 14926 15085 15255 16361 16502 16568 16609 16645 16873 17303 17387 17530 17985 18060 18281 18300 18375 18683 18726 19144 19647 19680 19857 19895 20089 20136 20591 20699 20713 21209 21296 21438 21728-21729 22535 22681 22687 22739 22759 22851 22854 22861-22863 22950 23144 23471 23503 23548-23549 24566 24580 24590 24716 24897 25015 25156 25266 25310 25314 25411 25433 26005 26020 26210 26248 26282 26300 26699 27019 27058 27110 27201 27462 27635 27648 27653 28006 28159 28277 28417 28450 28530 30505 30749 30883 31011 31062 31319 31502 32426 32457 32650 33257 33334 33398 33655 33767 34054 34289 34406 34535 34622 34780 34839 35020 35471 35499 35572 35864 35923 36418 36602 36640 36956-36957 37502 38039 38145 38176 38322 38359 39140 39482 39807 40228 40297 40332 40623 40669 40882 40901 40941 41557 42981-42982 42986 42988-42989 43422 43966 44118 44226 44251 44286 44309 44311 44316-44317 44358 44360 44363 44365-44366 44372 44376 44385 44388 44603 44644 44807 44954 45023 45175 45564 46138 46208 46334 46384 47012 47640 47828 48438 48462 48957 48990 49036 491398.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/566/A130?format=asciiOpticaldefaultJ/A+A/566/A130/rotationVariability and rotation measurementsSimbadNameSimbad column added by the CDSmeta.idchare_Ksmagrms uncertainty on Ksmagmagstat.error;phot.mag;em.IR.KfloatrecnoRecord number assigned by the VizieR team.
