抄録/ポイント： 惑星形成のコア降着モデルに挑戦し,ディスク不安定性モデルを支持するように見える,重力マイクロレンズ事象OGLE-2015-BLG-1649の解析からの外惑星の発見について報告する。惑星/ホスト-星質量比はq=7.2×10-3で,角度Einstein半径に正規化した投影分離はs=0.9である。著者らは,Subaru望遠鏡上の赤外Cameraと分光写真(IRCS)カメラを用いて高分解能追跡観察を行い,レンズフラックスに上限を置くことができた。これらの測定から,著者らは,質量がG型矮性に等しいか等しいすべての宿主星を除外することができる。これらの新しいフラックス制約によるBayes解析を行い,ホスト星と惑星の質量を推定した。これらは,それぞれ,M_L=0.34±0.19M_(太陽)であった。システムへの距離は。投影された星-惑星分離がある。推定された相対レンズ源の適切な運動,~7.1Ma yr-1はかなり高く,従って,追加の追跡観測がイベントの数年後に実施されるならば,レンズはより良く制約される。Please refer to the publisher for the copyright holders.
