马星望远镜证实, 高玛-卡斯X射线来自磁性白矮星而不是恒星本身. XRISM telescope confirms gamma-Cas X-rays come from magnetic white dwarf, not the star itself.

已揭开了西欧佩亚星系中一个明亮的恒星 - - 加玛卡斯 (gamma-Cas) 的50年神秘之处, Astronomers have solved a 50-year mystery about gamma-Cas, a bright star in Cassiopeia, revealing that its intense X-rays come from a magnetic white dwarf companion, not the star itself. 通过XRISM望远镜证实了这一点, The XRISM telescope confirmed this by showing the X-ray emissions move in sync with the white dwarf's orbit. 这一发现确定了玛-卡斯是Be+白矮星双星系统,重塑恒星演变的模型. This discovery identifies gamma-Cas as a Be + white dwarf binary system, reshaping models of stellar evolution.
