继与泛行星系外行星的TraCS之后：Wendelstein-1b和Wendelstein-2b
Following the TraCS of exoplanets with Pan-Planets: Wendelstein-1b and Wendelstein-2b
摘要：
随着恒星质量的减少，热彗星似乎变得越来越稀少。泛行星凌日巡天的目标是探测这类行星，并对其频率进行统计。在这里，我们宣布发现并验证了在该调查中发现的两颗行星，Wendelstein-1b和Wendelstein-2b，这是两颗围绕晚K宿主恒星运行的短周期热彗星。我们验证了他们都通过传统的径向速度测量方法与高分辨率阶梯光谱仪（HIRES）和可移动区行星轨道（HPF）仪器，然后通过他们的过境颜色签名（TraCS）。我们在$4000 - 24000$ Angström的波长范围内观察到目标，并进行了同步多波段过境拟合，并通过二次日食观测确定了它们的热发射。Wendelstein-1b是一颗热木星，半径为$1.0314_{-0.0061}^{+0.0061}$ $R_J$，质量为$0.592_{-0.129}^{+0.165}$ $M_J$，以$2.66$ d的周期绕一颗K7 V矮星运行，表面温度估计约为$1727_{-90}^{+78}$ K。Wendelstein-2b是一颗热木星，半径为$1.1592_{-0.0210}^{+0.0204}$ $R_J$，质量为$0.731_{-0.311}^{+0.541}$ $M_J$，以$1.75$ d的周期绕一颗K6 V矮星运行，表面温度估计约为$1852_{-140}^{+120}$ K。有了这个，我们证明了多波段测光是验证凌日系外行星的有效方法，特别是对于较暗的目标，因为径向速度（RV）的后续行动变得越来越昂贵的这些目标。
英文摘要：
Hot Jupiters seem to get rarer with decreasing stellar mass. The goal of the Pan-Planets transit survey was the detection of such planets and a statistical characterization of their frequency. Here, we announce the discovery and validation of two planets found in that survey, Wendelstein-1b and Wendelstein-2b, which are two short-period hot Jupiters that orbit late K host stars. We validated them both by the traditional method of radial velocity measurements with the HIgh Resolution Echelle Spectrometer (HIRES) and the Habitable-zone Planet Finder (HPF) instruments and then by their Transit Color Signature (TraCS). We observed the targets in the wavelength range of $4000 - 24000$ Angström and performed a simultaneous multiband transit fit and additionally determined their thermal emission via secondary eclipse observations. Wendelstein-1b is a hot Jupiter with a radius of $1.0314_{-0.0061}^{+0.0061}$ $R_J$ and mass of $0.592_{-0.129}^{+0.165}$ $M_J$, orbiting a K7V dwarf star at a period of $2.66$ d, and has an estimated surface temperature of about $1727_{-90}^{+78}$ K. Wendelstein-2b is a hot Jupiter with a radius of $1.1592_{-0.0210}^{+0.0204}$ $R_J$ and a mass of $0.731_{-0.311}^{+0.541}$ $M_J$, orbiting a K6V dwarf star at a period of $1.75$ d, and has an estimated surface temperature of about $1852_{-140}^{+120}$ K. With this, we demonstrate that multiband photometry is an effective way of validating transiting exoplanets, in particular for fainter targets since radial velocity (RV) follow-up becomes more and more costly for those targets.
