cds-question@unistra.frvisible-astronomyWide-band photometryinfrared-photometryf-starsdwarf-starsWe have conducted a study of debris disks around F stars in order to explore correlations between rotation, stellar winds, and circumstellar disks. We obtained new 24{mu}m photometry from the Multiband Imaging Photometer for Spitzer (MIPS) camera for a sample of 188 relatively nearby F dwarfs with various rotation rates and optical colors, and combined it with archival MIPS data for 66 more F stars, as well as Wide-field Infrared Survey Explorer data for the entire sample, plus 9 more F stars. Based on the objects' K_s_-[24] and [3.4]-[22] colors, we identify 22 stars in our sample as having 22 and/or 24{mu}m excesses above our detection limit, 13 of which are new discoveries. Our overall disk detection rate is 22/263, or 8%, consistent with previous determinations of disk fractions in the solar neighborhood. While fast-rotating stars are expected to have strong winds capable of efficiently removing dust, we find no correlation between rotational velocity and infrared excess. Similarly, we find no significant difference in excess detection rate between late-type F stars, which have convective surfaces, and early-type F stars, which have fully radiative envelopes. However, the essentially unknown range of ages in this sample may be washing out any effects relating rotation, winds, and disks.2012AJ....144..135Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/144/135CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/311 : WISE All-Sky Data Release (Cutri+ 2012)V/130 : Geneva-Copenhagen Survey of Solar neighbourhood III (Holmberg+, 2009)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)I/259 : The Tycho-2 Catalogue (Hog+ 2000)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)J/ApJ/738/122 : ScoCen debris disks Around F- and G-type stars (Chen+, 2011)J/ApJS/186/259 : Taurus Spitzer survey: new candidate members (Rebull+, 2010)J/A+A/493/1099 : CaII HK emission in rapidly rotating stars (Schroeder+, 2009)J/A+A/498/949 : Velocities of 1253 F-K dwarfs in open clustersJ/ApJ/698/1 : Spitzer observations of NGC 2362 (Currie+, 2009)J/ApJ/679/720 : Spitzer observations of the Hyades (Cieza+, 2008)J/ApJ/660/1556 : Characterization of dusty debris disks (Rhee+, 2007)J/ApJ/653/675 : Spitzer 24{mu}m photometry of A dwarfs (Su+, 2006)J/ApJ/646/297 : Spitzer observations of pre-main-sequence starshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/144/135https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/144/135http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/144/135https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/144/135https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/144/135http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/144/135GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/144/135/table1 (Photometry and ancillary data of Hipparcos F stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/144/135/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/144/135/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/144/135/table1?GETtext/xml+votable180.050000true1.3798478-9.61746940.0055555555555555566/309 353 455 545 725 770 1060 1167 1606 1888 2187 2433 2441 2455 2562 2819 3168 3199 3308 3441 3627 3765 3986 4465 4854 4957 5113 5154 5235 5770 5917 6073 6130 6165 6204 6339 6423 6766 6941 6979 7115 7227 7347 7958 8682 8717 8746 8787 8896 8923 8985 9210 9285 9705 9808 9955 10247 10556 11101 11204 11225 11335 11444 11523 11620 11857 11858 12282 12388 12531 12702 12825 13000 13311 13725 14052 14246 14859 14994 15170 15522 15638 15750 15871 16412 16600 16697 16807 16872 16929 17030 17121 17256 17274 17504 17555 17576 17669 18133 18289 18359 18427 18473 18889 18915 18926 19217 19266 19312 19345 19848 20186 20491 20642 20695 21056 21266 21285 21869 22043 22120 22285 22479 22594 22874 23140 23155 23305 23335 23369 23489 23826 23974 24303 24315 24399 24703 24777 24842 25056 25405 25717 25896 25911 26652 26753 27006 27032 27326 27614 27637 27808 27980 28192 28238 28451 28600 28763 29136 29160 29225 29483 29608 29698 29774 29805 30175 30450 30458 30703 30823 30910 31325 31848 32072 32205 32230 32772 33092 33188 33211 33325 33721 33838 34049 34081 34192 34217 34244 34336 34384 34409 34567 35257 35279 35588 35985 36555 36669 36808 36983 37543 37582 37767 37780 37898 38005 38080 38535 39025 39082 39149 39280 39289 39353 39406 39555 39730 39744 39841 39971 40198 40933 40950 41103 41136 41167 41980 41984 42028 42522 42555 42563 42596 43351 43426 43841 43906 44136 44220 44258 44755 44833 45538 45569 45677 45893 45921 45935 46113 46119 46987 47385 47598 47626 48143 48319 48334 48627 48651 48860 48883 48967 491496.772611666688002e-21 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/144/135?format=asciiOpticalInfrareddefaultJ/AJ/144/135/table1Photometry and ancillary data of Hipparcos F starsWDisplay the data from WISE All-Sky Data Release (2012, Cat.
