The event OGLE-2019-BLG-1180 has unambiguous cusp-passing and caustic-crossing anomalies, which were caused by a wide planetary caustic with s~2, where s is the star-planet separation in units of the angular Einstein radius {Teta}_E_. Thanks to well-covered anomalies by the Korea Micorolensing Telescope Network (KMTNet), we measure both the angular Einstein radius and the microlens parallax in spite of a relatively short event timescale of t_E_=28 days. However, because of a weak constraint on the parallax, we conduct a Bayesian analysis to estimate the physical lens parameters. We find that the lens system is a super-Jupiter-mass planet of M_p_=1.75_-0.51_^+0.53^M_J_ orbiting a late-type star of M_h_=0.55_-0.26_^+0.27^M{sun} at a distance D_L_=6.1_-1.3_^+0.9^kpc. The projected star-planet separation is a{perp}=5.19_-1.23_^+0.90^au, which means that the planet orbits at about four times the snow line of the host star. Considering the relative lens-source proper motion of {mu}_rel_=6mas/yr, the lens will be separated from the source by 60mas in 2029. At that time one can measure the lens flux from adaptive optics imaging of Keck or a next-generation 30m class telescope. OGLE-2019-BLG-1180Lb represents a growing population of wide-orbit planets detected by KMTNet, so we also present a general investigation into prospects for further expanding the sample of such planets.2023AJ....166..253Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/166/253CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AJ/159/262 : OGLE/KMTnet VI photometry of OGLE-2019-BLG-0551 (Mroz+, 2020)J/AJ/160/255 : KMTNet & OGLE I-photometry of KMT-2019-BLG-0842 (Jung+, 2020)J/ApJ/903/L11 : OGLE and KMTNet light curve of OGLE-2016-BLG-1928 (Mroz+, 2020)J/AJ/162/203 : Photometry of OGLE-2019-BLG-0304 with OGLE & KMTNet (Han+, 2021)J/AJ/164/102 : OGLE, KMTNet & Spitzer EWS2017-BLG-1038 lc (Malpas+, 2022)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/166/253https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/166/253http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/166/253https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/166/253https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/166/253http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/166/253GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/166/253/fig1Light curve of the best-fit parallax+orbital lens model of OGLE-2019-BLG-1180recnoRecord number assigned by the VizieR team.
