论文摘要

我们确认了苔丝发现的两个天然气巨头的行星性质。 TOI-3714($ v = 15.24,〜j = 11.74 $)是M2矮人,托管热木星($ m_p = 0.70 \ pm 0.03〜 \ mathrm {m_j} $ {m_j} $和$ r_p = 1.01 0.000001 $天与已解决的白矮人伴侣。 TOI-3629($ V = 14.63,〜J = 11.42 $)是M1矮人,托管热木星($ m_p = 0.26 \ pm 0.02〜\ pm 0.02〜\ mathrm {m_j} $和$ r_p = 0.74 $ 3.936551 _ { - 0.000006}^{+0.000005} $ days。我们使用基于地面和空间的光度法,斑点成像以及来自可居住区的行星查找器和NEID光谱仪的高精度速度计的组合来表征每个过渡伴侣。随着这两个系统的发现,现在已经有9个M矮人可以容纳过境的热木星。 Among this population, TOI-3714 b ($T_{eq}=750\pm20$ K and $\mathrm{TSM}=98\pm7$) and TOI-3629 b ($T_{eq}=690\pm20$ K and $\mathrm{TSM}=80\pm9$) are warm gas giants amenable to additional characterization with transmission探测大气化学的光谱和对于TOI-3714,是倾斜的测量,以探测形成的情况。

We confirm the planetary nature of two gas giants discovered by TESS to transit M dwarfs. TOI-3714 ($V=15.24,~J=11.74$) is an M2 dwarf hosting a hot Jupiter ($M_p=0.70 \pm 0.03~\mathrm{M_J}$ and $R_p=1.01 \pm 0.03~\mathrm{R_J}$) on an orbital period of $2.154849 \pm 0.000001$ days with a resolved white dwarf companion. TOI-3629 ($V=14.63,~J=11.42$) is an M1 dwarf hosting a hot Jupiter ($M_p=0.26 \pm 0.02~\mathrm{M_J}$ and $R_p=0.74 \pm 0.02~\mathrm{R_J}$) on an orbital period of $3.936551_{-0.000006}^{+0.000005}$ days. We characterize each transiting companion using a combination of ground-based and space-based photometry, speckle imaging, and high-precision velocimetry from the Habitable-zone Planet Finder and the NEID spectrographs. With the discovery of these two systems, there are now nine M dwarfs known to host transiting hot Jupiters. Among this population, TOI-3714 b ($T_{eq}=750\pm20$ K and $\mathrm{TSM}=98\pm7$) and TOI-3629 b ($T_{eq}=690\pm20$ K and $\mathrm{TSM}=80\pm9$) are warm gas giants amenable to additional characterization with transmission spectroscopy to probe atmospheric chemistry and, for TOI-3714, obliquity measurements to probe formation scenarios.
