$η$海脊的变化状态:1998- 2021年HST的测光记录
The Altered State of $η$Carinae: HST's Photometric Record 1998--2021
摘要:
哈勃太空望远镜对$η$船底座的测光跨度为23年,包括5次光谱事件。2010年后快速增亮速率下降,2014年和2020年的光谱事件具有与前辈不同的光变曲线。与其他指标一起,这些发展可能预示着$η$ Car状态变化的结论。
英文摘要:
Hubble Space Telescope photometry of $η$ Carinae spans 23 years, including five spectroscopic events. The rapid brightening rate decreased after 2010, and the spectroscopic events in 2014 and 2020 had light curves different from their predecessors. Together with other indicators, these developments probably foretell the conclusion of $η$ Car's change of state.
