论文摘要
我们介绍了从过境系外行星调查卫星（$ TESS $）任务中发现两个新的10天巨型行星，他们的群众是使用大量地面设施的多样性确定的。 TOI-481 B和TO-892 B具有相似的半径（$ 0.99 \ pm0.01 $ $ $ \ rm \ r_ r_ {j} $和$ 1.07 \ pm0.02 $ $ $ $ \ r_ r_ {j} $，分别为r_ {j} $），以及节期（分别是10.3311天和10.6261616 $ 0.1.6266 $），但是0.6266 $。 $ \ rm m_ {j} $ vess $ 0.95 \ pm0.07 $ $ $ \ rm m_ {j} $）。这两个行星轨道金属富含恒星（[fe/h] = $+0.26 \ pm 0.05 $ dex和[fe/h] = $+0.24 \ pm 0.05 $ dex，分别为TOI-481和TOI-892），但在不同的进化阶段。 toi-481是$ \ rm m _ {\ star} $ = $ 1.14 \ pm0.02 $ $ $ \ rm m _ {\ odot} $，$ \ rm r _ {\ star} $ = $ = $ 1.66 \ pm0.02 $ pm0.02美元EFF} $ = $ 5735 \ pm 72 $ k），年龄为6.7 Gyr，在主序列的关键点处。另一方面，TOI-892是F-Type Dwarf Star（$ t _ {\ rm eff} $ = $ 6261 \ pm 80 $ k），其质量为$ \ rm m _ {\ star} $ = $ = $ = $ 1.28 r _ {\ star} $ = $ 1.39 \ pm0.02 $ $ \ rm r _ {\ odot} $。 TOI-481 B和TOI-892 B加入了超过10天的轨道周期的几乎没有人口稠密的地区，这对于约束热木星的形成和结构的理论很重要。
We present the discovery of two new 10-day period giant planets from the Transiting Exoplanet Survey Satellite ($TESS$) mission, whose masses were precisely determined using a wide diversity of ground-based facilities. TOI-481 b and TOI-892 b have similar radii ($0.99\pm0.01$ $\rm R_{J}$ and $1.07\pm0.02$ $\rm R_{J}$, respectively), and orbital periods (10.3311 days and 10.6266 days, respectively), but significantly different masses ($1.53\pm0.03$ $\rm M_{J}$ versus $0.95\pm0.07$ $\rm M_{J}$, respectively). Both planets orbit metal-rich stars ([Fe/H]= $+0.26\pm 0.05$ dex and [Fe/H] = $+0.24 \pm 0.05$ dex, for TOI-481 and TOI-892, respectively) but at different evolutionary stages. TOI-481 is a $\rm M_{\star}$ = $1.14\pm0.02$ $\rm M_{\odot}$, $\rm R_{\star}$ = $1.66\pm0.02$ $\rm R_{\odot}$ G-type star ($T_{\rm eff}$ = $5735 \pm 72$ K), that with an age of 6.7 Gyr, is in the turn-off point of the main sequence. TOI-892, on the other hand, is a F-type dwarf star ($T_{\rm eff}$ = $6261 \pm 80$ K), which has a mass of $\rm M_{\star}$ = $1.28\pm0.03$ $\rm M_{\odot}$, and a radius of $\rm R_{\star}$ = $1.39\pm0.02$ $\rm R_{\odot}$. TOI-481 b and TOI-892 b join the scarcely populated region of transiting gas giants with orbital periods longer than 10 days, which is important to constrain theories of the formation and structure of hot Jupiters.
