论文摘要
我们报告了两条行星的验证，该行星绕着附近的（36pc）M2矮人TOI-1266观察到了苔丝任务。内行星的轨道周期为10.9天（$ r = 2.46 \ pm 0.08 r_ \ oplus $）。外行星的半径为$ 1.67 _ { - 0.11}^{+0.09} r_ \ oplus $，并驻留在系外行星和气态行星之间的过渡区域。轨道周期为18.8天，外行星的暴发通量为地球的2.4倍，类似于维纳斯的日晒。使用具有可居住区域的Planet Finder光谱仪的精确近红外径向速度，我们将上部质量限制为$ 15.9 m_ \ oplus $和$ 6.4 m_ \ oplus $分别对内部和外部星球的信心为95％。鉴于宿主星亮度（v = 12.9，j = 9.7），可以通过当前的RV仪器实现的更精确的行星C质量约束将产生进一步的见解，以了解雕刻外部行星半径谷的主要过程。
We report on the validation of two planets orbiting the nearby (36pc) M2 dwarf TOI-1266 observed by the TESS mission. The inner planet is sub-Neptune-sized ($R=2.46 \pm 0.08 R_\oplus$) with an orbital period of 10.9 days. The outer planet has a radius of $1.67_{-0.11}^{+0.09} R_\oplus$ and resides in the exoplanet Radius Valley---the transition region between rocky and gaseous planets. With an orbital period of 18.8 days, the outer planet receives an insolation flux of 2.4 times that of Earth, similar to the insolation of Venus. Using precision near-infrared radial velocities with the Habitable-zone Planet Finder Spectrograph, we place upper mass limits of $15.9 M_\oplus$ and $6.4 M_\oplus$ at 95% confidence for the inner and outer planet, respectively. A more precise mass constraint of planet c, achievable with current RV instruments given the host star brightness (V=12.9, J=9.7), will yield further insights into the dominant processes sculpting the exoplanet Radius Valley.
