论文摘要
Makemake是最明亮的已知跨纳普族对象之一，因此已被广泛观察到。然而，它对近红外光谱可见，尚未在中等分辨的能力中完全观察到，旨在详细研究CH $ _4 $冰的吸收特征。在本文中，我们介绍了在非常大的望远镜（智利）上观察到的X射击器的Makemake谱。我们分析了检测到的特征，测量了它们的位置和深度。此外，我们将Makemake的频谱与Eris的频谱进行了比较，Eris的频谱使用相同的仪器和相似的设置获得，以结论，两个对象中Ch $ _4 $冰的频带都显示出相似的变化。
Makemake is one of the brightest known trans-Neptunian objects, as such, it has been widely observed. Nevertheless, its visible to near-infrared spectrum has not been completely observed in medium resolving power, aimed at studying in detail the absorption features of CH$_4$ ice. In this paper we present the spectrum of Makemake observed with X-Shooter at the Very Large Telescope (Chile). We analyse the detected features, measuring their location and depth. Furthermore, we compare Makemake's spectrum with that of Eris, obtained with the same instrument and similar setup, to conclude that the bands of the CH$_4$ ice in both objects show similar shifts.
