本文通过ESO152望远镜的PLATOSpec联盟观测CC Eri双星,利用阶梯光栅摄谱仪研究其CME与耀斑,协调g'波段测光补充白光耀斑验证,给出观测初步结果。
AI 中文摘要
近年来,恒星日冕物质抛射(CME)及耀斑/超级耀斑的研究备受关注,因其与行星宜居性及恒星演化密切相关。为此,我们利用位于拉西拉的ESO152望远镜开展观测,该望远镜由PLATOSpec联盟运营,观测对象为晚K型/早M型矮星双星CC Eri。ESO152望远镜当前配备了阶梯光栅摄谱仪,可覆盖宽光谱范围,便于研究不同谱线中的CME及耀斑/超级耀斑。观测期间,CC Eri未被TESS观测到,但我们协调了g'波段测光以交叉验证白光耀斑,本文呈现了该观测 campaign 的初步结果。
英文摘要
In the recent past investigations of stellar Coronal Mass Ejections (CMEs) and flares/superflares gained special attention because of their relevance for planetary habitability and stellar evolution. With respect to that, we present an observing campaign at the ESO152 telescope on LaSilla operated by the PLATOSpec consortium of the late-K/early-M dwarf binary CC Eri. The ESO152 telescope is currently equipped with an Echelle spectrograph which enables the investigation of a broad spectral range, allowing the investigation of CMEs and flares/superflares in various spectral lines. Within the observing campaign CC Eri was not observed by TESS, but we have coordinated g'-band photometry to cross-check for white light flares. Preliminary results of the observing campaign are presented.
