摘要
BRITE-Constellation 致力于在红和/或蓝波段对分布于银河系各处的亮星进行高精度光学测光监测。空间测光避免了湍流且吸收光线的地球大气，并允许以高时间分辨率进行极长且连续的观测，从而提供理解恒星内部（如星震学）及其近邻环境各种过程所需的数据。虽然首批空间天文观测聚焦于地面无法到达的光谱区，但约在1970年前后人们很快意识到，避开湍流地球大气显著提高了测光精度，并由此发射了专门致力于高质量测光的卫星。一个完美的例子是 BRITE-Constellation，它是奥地利、加拿大和波兰之间非常成功合作的成果。本文展示了几乎覆盖整个赫罗图（HRD）目标的研究亮点，但主要关注大质量高温恒星。
