cds-question@unistra.frexoplanetsgravitational-lensinginfrared-photometryvisible-astronomyphotometryWe investigate the gravitational microlensing event KMT-2019-BLG-1715, the light curve of which shows two short-term anomalies from a caustic-crossing binary-lensing light curve: one with a large deviation and the other with a small deviation. We identify five pairs of solutions, in which the anomalies are explained by adding an extra lens or source component in addition to the base binary-lens model. We resolve the degeneracies by applying a method in which the measured flux ratio between the first and second source stars is compared with the flux ratio deduced from the ratio of the source radii. Applying this method leaves a single pair of viable solutions, in both of which the major anomaly is generated by a planetary-mass third body of the lens, and the minor anomaly is generated by a faint second source. A Bayesian analysis indicates that the lens comprises three masses: a planet-mass object with ~2.6M_J_ and binary stars of K and M dwarfs lying in the galactic disk. We point out the possibility that the lens is the blend, and this can be verified by conducting high-resolution follow-up imaging for the resolution of the lens from the source.2021AJ....161..270Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/161/270CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/528/A42 : VRi light curves of the lensed QSO HE 0435-1223 (Ricci+, 2011)J/A+A/551/A104 : Lensed QSO UM673/Q0142-100 VRi light curves (Ricci+, 2013)J/AJ/154/210 : 2015 high-cadence Spitzer microlensing events (Zhu+, 2017)J/AJ/159/98 : I-band LC of microlensing event KMT-2016-BLG-1836 (Yang+, 2020)J/AJ/159/116 : I-band light curves of OGLE-2015-BLG-1771Lb (Zhang+, 2020)J/AJ/159/256 : Light curve of OGLE-2018-BLG-0677 (Herrera-Martin+, 2020)J/AJ/159/261 : LC of microlensing event OGLE-2012-BLG-0838 (Poleski+, 2020)J/AJ/159/262 : OGLE/KMTnet VI bands photo. of OGLE-2019-BLG-0551 (Mroz+, 2020)J/AJ/160/74 : Optical and IR photometry of OGLE-2017-BLG-0406 (Hirao+, 2020)J/AJ/160/148 : RI-band LC microlensing event OGLE-2018-BLG-1269Lb (Jung+,2020)J/AJ/160/255 : KMTNet & OGLE I-band photo. of KMT-2019-BLG-0842 (Jung+, 2020)J/A+A/649/A90 : KMT-2018-BLG-1025Lb I light curve (Han+, 2021)J/AJ/161/54 : VRI photometry of MOA 2009-BLG-319 (Terry+, 2021)J/AJ/161/293 : LCs of OGLE-2018-BLG-0567 and OGLE-2018-BLG-0962 (Jung+, 2021)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/161/270https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/161/270http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/161/270https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/161/270https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/161/270http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/161/270GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/AJ/161/270/figure1Combined table from original tablesrecnoRecord number assigned by the VizieR team.
