ESPRESSO光谱数据集

ESPRESSO光谱数据集是由波尔图大学天文研究所的研究团队创建的，包含了30颗Gaia基准星的超高分辨率光谱数据。这些数据是通过ESPRESSO光谱仪在VLT上观测得到的，旨在为不同的光谱巡天提供校准星。数据集中的星数据具有非常高质量和均匀性，对于比较研究多颗星至关重要。该数据集的应用领域包括星体参数的精确测量和化学丰度的研究，旨在解决星体形成、演化和当前特征的问题。

The ESPRESSO Spectral Dataset was developed by a research team at the Institute of Astronomy, University of Porto, and encompasses ultra-high-resolution spectral data from 30 Gaia benchmark stars. All data were acquired via observations conducted with the ESPRESSO spectrograph at the Very Large Telescope (VLT), with the core objective of supplying calibration stars for multiple spectroscopic surveys. The stellar data within this dataset features outstanding quality and high uniformity, making it essential for comparative studies of multiple stellar objects. Applications of this dataset include precise measurements of stellar parameters and investigations of stellar chemical abundances, with the overarching goal of resolving fundamental questions about stellar formation, evolution, and present-day stellar properties.
