cds-question@unistra.fram-starsvariable-starsccd-photometryWe have studied over 1600 Am stars at a photometric precision of 1mmag with SuperWASP photometric data. Contrary to previous belief, we find that around 200 Am stars are pulsating delta Sct and gamma Dor stars, with low amplitudes that have been missed in previous, less extensive studies. While the amplitudes are generally low, the presence of pulsation in Am stars places a strong constraint on atmospheric convection, and may require the pulsation to be laminar. While some pulsating Am stars have been previously found to be delta Sct stars, the vast majority of Am stars known to pulsate are presented in this paper. They will form the basis of future statistical studies of pulsation in the presence of atomic diffusion.2011A&A...535A...3Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/535/A3CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/260 : General Catalogue of Ap and Am stars (Renson+ 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/535/A3https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/535/A3http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/535/A3https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/535/A3https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/535/A3http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/535/A3GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/535/A3/table1 (Pulsating Am stars observed)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/535/A3/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/535/A3/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/535/A3/table1?GETtext/xml+votable180.050000true1.601208334.60688890.0055555555555555566/1286-1287 1296 1300 2363 2433 2714 2831 3332 3336 3360 3598 5195 5394 5453 5517 5718 6590 7340 9311 9590 9598 9618 10372 10391 10456 10790 10798 10803 10896 13267 13278 13350 13533 13686 14121 15113 15118 15132 15149 15477 15504 16417 16486 16493 16520 16592 16617 16709 17111 17316 17370 17412 17454 17463-17464 17640 17757 17969 18062 18092 18769 20227 20440 20567 20747 21064 21432 21860 21910 22718 23059 23105 23112 23769 23773 23897 24274 24276 24280 24338 24347 24355 24358-24359 24367 24381 24424-24425 24427 24452 24467 24469-24471 24486 24488-24489 24492 24495 24498-24499 24505-24506 24508 24510 24516-24517 24528 24545-24546 24609 24720 24760 24925 24933 25213 25269 25286 25624 25689 26168 26296 26741 26752 26789 27764 27895 27935 28097 28383 28496 28523 28628 30042 30850 33814 34240 34412 35222 35263 36150 36283 36400 36459 36638 36801 37876 38304 38364 38396 38521 38657 38739 38937 39076 39144 39482 39964 40150 40361 40416 40560 40752 40772 40793 40847 40885 40937 40945 42660 42797 42921 42929 43326 43385 43416 43459 43465 43507 43623 43668 43746 43789 43848 43894 43935 44198 44215 44362-44363 44376 44456 44676 44788 44802 45054 45300 45458 46692 46699 46720 46766 46773 46795 46816 46893 46898 46911 46920 47348 47517 47571 47936 48129 48408 48517 48752 48761 48763 48980 49029https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/535/A3?format=asciiOpticaldefaultJ/A+A/535/A3/table1Pulsating Am stars observedSimbadNameSimbad column added by the CDSmeta.idcharSpTypeMK spectral Typesrc.spTypecharrecnoRecord number assigned by the VizieR team.
