Gaia Data Release 3 (DR3)

该数据集主要关注具有基本特性的主序星，包括表面温度（开尔文为单位）、半径（太阳半径为单位）、绝对星等和亮度（以太阳亮度为单位）。此外，该数据集被用于分析表面温度对恒星亮度的影响，以及它与恒星半径和绝对星等之间的相关性。该目录规模宏大，包含超过18亿颗恒星，重点样本为240颗恒星。任务是对斯特藩-玻尔兹曼定律进行实证验证，该定律关联了恒星的温度和亮度。

This dataset primarily focuses on main-sequence stars with fundamental stellar properties, including surface temperature (in Kelvin), radius (in solar radii), absolute magnitude, and luminosity (in solar luminosities). Additionally, this dataset is used to analyze the impact of surface temperature on stellar luminosity, as well as the correlations among surface temperature, stellar radius and absolute magnitude. This is a large-scale catalog containing over 1.8 billion stars, with a focused sample of 240 stars. The task is to conduct empirical validation of the Stefan-Boltzmann Law, which relates stellar temperature and luminosity.
