cds-question@unistra.frlate-type-starsgiant-starssupergiant-starseffective-temperatureOf a total of 177 cool G, K and M giants and supergiants, we measured the MgII h+k line emission of extended chromospheres in high-resolution (LWR) International Ultraviolet Explorer (IUE) spectra by using the IUE final data archive at the Space Telescope Science Institute (STScI) and derived the respective stellar surface fluxes. They represent the chromospheric radiative energy losses presumably related to basal heating by the dissipation of acoustic waves, plus a highly variable contribution due to magnetic activity.2011MNRAS.414..418Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/414/418CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVI/110 : Final Merged Log of IUE Observations (NASA-ESA, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/414/418https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/414/418http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/414/418https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/414/418https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/414/418http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/414/418GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/414/418/table1 (Physical and empirical surface fluxes of the chromospheric MgII h+k line emission of 177 cool giants and supergiants from the IUE final data archive, together with B-V, V, BC and logTeff (see Section 2))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/414/418/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/414/418/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/414/418/table1?GETtext/xml+votable180.050000true1.3339247-5.70761890.0055555555555555566/15 341 737 846 1143 1399 1427 2133 2282 2623 2837 2839 2973 3077 3229 4146 4444 4559 4574 4699 4990 5109 5245 5382 5535 5718 6126 6166 6219 6241 6740 7402 7610 8133 8689 8767 9083 9127 9213 9219 9520 9610 10055 10101 10380 10490 11473 11547 11958 12009 12082 12155 12176 12544 12604 12748 12964 13158 13282 13392 13550 14005 14632 14721 15364 15628 15715 15749 16148 16834 17266 17368 17397 17551 17608 18204 18547 18893 19045 19930 20102 20205 20261 20311 20518 20761 20886 21050 21073 21523 21530 21567 21612 21738 22015 22964 23533 23538 23540 23547 23611 23695 23995-23996 24420 24877 25246 25278 25304 26302 26320 26552 26758 27752 28151 28692 28705 28959 28968 29533 30339 30567 30693 30953 30958 31187 31475 31576 31784 32182 32575 32754 32891 33034 33201 33797 34392 35069 35459 35480 36233 36317 36759 37327 37708 37907 38095 38562 38718 38957 39095 39165 39355 39714 39864 39893 40795 41022 41039 41270 41839 42081 43046 43141 43494 44015 44075 44248 45164 45530 45874 46334 47424 48051 48516 48572 48886https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/414/418?format=asciiOpticaldefaultJ/MNRAS/414/418/table1Physical and empirical surface fluxes of the chromospheric MgII h+k line emission of 177 cool giants and supergiants from the IUE final data archive, together with B-V, V, BC and logTeff (see Section 2)_DEDeclination (J2000) from SIMBAD (not part of the original data)degpos.eq.dec;meta.mainrecnoRecord number assigned by the VizieR team.
