cds-question@unistra.frmultiple-starssolar-system-planetsThe K2 mission has recently begun to discover new and diverse planetary systems. In December 2014 Campaign 1 data from the mission was released, providing high-precision photometry for ~22000 objects over an 80 day timespan. We searched these data with the aim of detecting further important new objects. Our search through two separate pipelines led to the independent discovery of K2-19b & c, a two-planet system of Neptune sized objects (4.2 and 7.2R_{earth}_), orbiting a K dwarf extremely close to the 3:2 mean motion resonance. The two planets each show transits, sometimes simultaneously due to their proximity to resonance and alignment of conjunctions.2015A&A...582A..33Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/582/A33CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/579/A19 : K2 Variable Catalogue (Armstrong+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/582/A33https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/582/A33http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/582/A33https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/582/A33https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/582/A33http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/582/A33GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/582/A33/nitesK2-19b data taken with the NITES telescope plotted in Figure 1recnoRecord number assigned by the VizieR team.
