抄録/ポイント： LTT 1445は,6.86pcの距離に位置する階層的三重M-dwarf星システムである。1次星LTT 1445A(0.257M_(Sun))は,5.36日の軌道周期で輸送惑星LTT 1445Abをホストすることが知られている。Transiting Exoplant調査衛星データを用いて,3.12日の軌道周期で,LTT 1445システムにおける第2惑星の発見を示した。著者らは,新しい世界がLTT 1445Aを軌道するのを確立するために,Rocky Exoplantsと安定分光観測,高精度放射速度平面探査機,高Resolution Echelle分光計,MAROON-X,およびPlanet Finder Spectrographの5つのスペクトログラフから得られた半径方向速度測定を組み合わせた。LTT 1445Abの質量と半径を2.87±0.25M_.+.とR_.+と決定し,地球様組成と一致した。新たに発見されたLTT 1445Acに対して,M_.+.および最小半径1.15R_.+の質量を測定したが,この光曲線の信号対ノイズ比として,半径を直接測定することができない。MEarth測光と地上分光法を用いて,星C(0.161M_(Sun))は1.4日回転周期の源であり,星B(0.215M_(Sun))は6.7日の回転周期を有する。LTT 1445Aの85日の推定可能な回転期間を推定した。このように,この三重M-dwarf系は,最も大規模なM矮が紡糸する特別な進化段階にあり,中間質量M矮は回転する過程にあり,一方,最小質量の恒星成分は,まだスピンダウンを開始しなかった。Please refer to the publisher for the copyright holders.
