X-Shooter拍摄的鸟神星
The Dwarf Planet Makemake as seen by X-Shooter
摘要：
鸟神星是已知的最明亮的海王星外天体之一，因此，它被广泛观察到。然而，在中等分辨率下，其可见-近红外光谱尚未被完全观测到，旨在详细研究CH $_4$冰的吸收特性。在本文中，我们提出了在甚大望远镜（智利）的X-射手观察到的鸟神星的光谱。我们分析检测到的特征，测量它们的位置和深度。此外，我们比较Makemake的光谱与厄里斯，获得相同的仪器和类似的设置，得出的结论是CH $_4$冰在这两个对象的频带显示出类似的位移。
英文摘要：
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.
