cds-question@unistra.frexoplanetsmultiple-starsstellar-radiieffective-temperaturemetallicitystellar-massesspectroscopyWe present 151 planet candidates orbiting 141 stars from K2 campaigns 5-8 (C5-C8), identified through a systematic search of K2 photometry. In addition, we identify 16 targets as likely eclipsing binaries, based on their light curve morphology. We obtained follow-up optical spectra of 105/141 candidate host stars and 8/16 eclipsing binaries to improve stellar properties and to identify spectroscopic binaries. Importantly, spectroscopy enables measurements of host star radii with ~10% precision, compared to ~40% precision when only broadband photometry is available. The improved stellar radii enable improved planet radii. Our curated catalog of planet candidates provides a starting point for future efforts to confirm and characterize K2 discoveries.2018AJ....155...21Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/155/21CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/809/25 : Stellar and planet properties for K2 candidatesJ/A+A/594/A100 : K2 new planetary and EB candidates (Barros+, 2016)J/ApJS/224/2 : K2 EPIC stellar properties for 138600 targets (Huber+, 2016)J/ApJS/226/7 : Planet candidates discovered using K2's 1st yrJ/ApJ/836/77 : A library of high-S/N optical spectra of FGKM starshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/155/21https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/155/21http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/155/21https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/155/21https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/155/21http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/155/21GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/155/21/table1 (Planet Candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/155/21/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/155/21/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/155/21/table1?GETtext/xml+votable180.050000true126.896935811.66747360.005555555555555556Cone search capability for table J/AJ/155/21/table2 (Stars with HIRES Spectra and Derived Parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/155/21/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/155/21/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/155/21/table2?GETtext/xml+votable180.050000true126.896935811.66747360.0055555555555555566/4247 4263 4268 4269 4271 4273 4279 4280 4281 4285 4296 4303 4320 4322 4346 4514 4521 4524 4624 4629 4632 4659 4660 4668 4677 4683 4687 4688 4698 4699 4700 4704 4716 4720 4723 4729 4730 4731 4733 4800 4816 4867 4875 4897 18003 18012 18026 18039 18132 18147 18208 18223 18228 18307 18314 18329 18347 18350 18361 18362 25604 25614 25616 25624 25626 25627 25648 25650 25673 25677 25696 25697 25698 25705 25721 25722 25725 25726 25735 25747 25750 25755 25757 25783 25792 25794 25795 25800 25804 25810 29002 29009 29010 29012 29017 29022 29031 29045 44719 44771 44779 48028 48031 48067 48088 48089 48099 48111 48113 48114 48121https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/155/21?format=asciidefaultJ/AJ/155/21/table1Planet Candidatese_Per[2e-06/0.005718] Lower uncertainty in Perdstat.error;stat.mindoublerecnoRecord number assigned by the VizieR team.
