抄録/ポイント： LHS 1678(TOI-696)外惑星系のTransiting Exoplant調査衛星(TESS)発見を示し,19.9pcで明るい(V_J=12.5,K_s=8.3)M_2矮性を示す2つのほぼ地球サイズの輸送惑星と,恐らく天文学的褐色の矮性軌道を,そのようにしたものである。”そのこと]を,2つのほぼ地球サイズの輸送惑星と,19.9pcで,明るい(V_J=12.5,K_s=8.3)M_2矮性軌道を軌道する。2つのTESS検出惑星は,それぞれ,0.86日と3.69日軌道で,半径0.70±0.04R_.+と0.98±0.06R_.+であった。両惑星は,地上ベースの追跡観察によって検証され,特性化される。高精度ラジアル速度Planet探索器RVモニタリングは,それぞれ,惑星bとcに対して,0.35M_.+.と1.4M_.+の97.7パーセンタイル質量上限を与えた。Cerro Toolo Inter-American Observatory/Smallと中庸開口望遠鏡システム0.9mによって検出される天文学的コンパニオンは,数十年のオーダーで軌道期間を持ち,他の手段によって検出されない。追加地上観測は,高質量褐色矮性あるいは小形である。各惑星はユニークな関心事である。内部惑星は超短周期を持ち,外側惑星はVenusゾーンにある。両者は,James Webb宇宙望遠鏡による大気特性評価と,極端な精度の半径方向速度による質量測定に対する有望なターゲットである。また,4.97日軌道における半径0.9±0.1R_.+.の3番目の惑星候補を,将来の研究における検証のための多サイクルTESSデータにおいて同定した。ホスト星はHertzsprung-Russellダイアグラムのより低い主配列で観察されたギャップと関連する。このギャップは,M矮星における部分から完全対流内部への遷移に結び付く,そして,外惑星進化に及ぼす関連する恒星天体物理学の影響は,現在未知である。これらのシステム特性の culminationは,LHS 1678を,比較外惑星科学に対してユニークな,説得力のある遊び地とし,低質量星を軌道する小,短周期外惑星の形成および進化を理解する。Please refer to the publisher for the copyright holders.
