论文摘要
我们介绍了由苔丝太空任务发现的三个热木星，TOI-1181b，TOI-1516B和TOI-2046b的确认和表征。据报道的热木星的轨道周期在1.4至2.05天之间。这三个行星的质量为$ 1.18 \ pm0.14 $ m $ _ {\ mathrm {j}} $，$ 3.16 \ pm0.12 $ \，m $ _ {\ mathrm {j}} $ TOI-1516B和TOI-2046b。 TOI-1181b的恒星宿主是F9IV恒星，而TOI-1516b和TOI-2046b轨道F主序列宿主星。前两个系统的年龄在2-5个回旋范围内。但是，TOI-2046是拥有热木星的少数最年轻的行星系统之一，年龄估计为100-400 MYR。这三个行星的径向速度随访所使用的主要仪器位于Ondčjov，Tautenburg和McDonald天文台，所有三个行星都安装在2-3米的孔径望远镜上，表明中端望远镜网络可以在巨大的巨大望远镜中发挥重要作用。 \ textit {plato}。
We present the confirmation and characterization of three hot Jupiters, TOI-1181b, TOI-1516b, and TOI-2046b, discovered by the TESS space mission. The reported hot Jupiters have orbital periods between 1.4 and 2.05 days. The masses of the three planets are $1.18\pm0.14$ M$_{\mathrm{J}}$, $3.16\pm0.12$\, M$_{\mathrm{J}}$, and 2.30 $\pm 0.28$ M$_{\mathrm{J}}$, for TOI-1181b, TOI-1516b, and TOI-2046b, respectively. The stellar host of TOI-1181b is a F9IV star, whereas TOI-1516b and TOI-2046b orbit F main sequence host stars. The ages of the first two systems are in the range of 2-5 Gyrs. However, TOI-2046 is among the few youngest known planetary systems hosting a hot Jupiter, with an age estimate of 100-400 Myrs. The main instruments used for the radial velocity follow-up of these three planets are located at Ondřejov, Tautenburg and McDonald Observatory, and all three are mounted on 2-3 meter aperture telescopes, demonstrating that mid-aperture telescope networks can play a substantial role in the follow-up of gas giants discovered by \textit{TESS} and in the future by \textit{PLATO}.
