论文摘要
我们提出了一种用于相曲线检索的新型出于物理动机的参数温度模型，能够自谨慎地评估多维中热结构的变化。为了开发这种方法，我们从完整的三维一般循环模型和分析配方中汲取了动力，这是潮汐锁定行星（行星射流）的主要动力学特征。我们的配方表现出显着的灵活性。它可以产生文献中看到的各种特征和重新分布效果的行星喷头，包括标准的向东和不寻常的向西偏移热点，以及更多的异国情调配置，以实现潜在的未来观察。在我们的建模方案中，我们利用了一组可拖动的参数有效的效率，以实现未来的贝叶斯分析，并且除了解决的温度结构外，我们还返回尚未从检索中得出的物理见解：幅度和相位偏置，以及赤道射流的位置和范围。
We present a novel physically motivated, parametrized temperature model for phase-curve retrieval, able to self-consistently assess the variation in thermal structure in multidimensions. To develop this approach, we drew motivation from both full three-dimensional general circulation models and analytic formulations, accounting for the dominant dynamical feature of tidally locked planets, the planetary jet. Our formulation shows notable flexibility. It can generate planetary jets of various characteristics and redistribution efficiencies seen in the literature, including both standard eastward and unusual westward offset hotspots, as well as more exotic configurations for potential future observations. In our modeling scheme we utilize a tractable set of parameters efficient enough to enable future Bayesian analysis and, in addition to the resolved temperature structure, we return physical insights not yet derived from retrievals: the amplitude and the phase offset, and the location and the extent of the equatorial jet.
