论文摘要
我们使用可用的苔丝光度法结合使用了温暖的木星的行星性质。高精度,近红外光谱,可居住区域发现者;以及斑点和自适应光学成像。该数据显示在$ \ sim29 $ -day轨道上的过渡伴侣,其质量和半径为$ 0.66 \ pm0.07 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ {J {J}} $和$ 1.15 _ { - 0.05}^{+0.04}^{+0.04} Star TOI-1899是众所周知的最低质量恒星,可以举办过境温暖的木星,我们讨论了一个温暖的($ \ Mathrm {t_t_ {eq}}} \ sim362 $ k)气体巨型旋转M0星的热烈的后续机会。我们的观察结果表明,TOI-1899.01是一种蓬松的木星,我们建议对精炼轨道并限制在苔丝中观察到的真正稀释的其他过境观察结果。
We confirm the planetary nature of a warm Jupiter transiting the early M dwarf TOI-1899, using a combination of available TESS photometry; high-precision, near-infrared spectroscopy with the Habitable-zone Planet Finder; and speckle and adaptive optics imaging. The data reveal a transiting companion on an $\sim29$-day orbit with a mass and radius of $0.66\pm0.07\ \mathrm{M_{J}}$ and $1.15_{-0.05}^{+0.04}\ \mathrm{R_{J}}$, respectively. The star TOI-1899 is the lowest-mass star known to host a transiting warm Jupiter, and we discuss the follow-up opportunities afforded by a warm ($\mathrm{T_{eq}}\sim362$ K) gas giant orbiting an M0 star. Our observations reveal that TOI-1899.01 is a puffy warm Jupiter, and we suggest additional transit observations to both refine the orbit and constrain the true dilution observed in TESS.
