摘要:

V4334 Sgr(又名Sakurai的天体)是一个古老行星状星云的中心恒星,在1996年被发现前几年经历了一次非常晚的热脉冲。自2001年以来,我们一直在监测光发射线光谱的演变。我们的目标是通过限制他们的中心恒星温度的时间演变来改善演化模型。此外,高分辨率光谱观测所获得的X-射手和ALMA显示的不同形态成分的时间演变。

英文摘要:

V4334 Sgr (a.k.a. Sakurai's object) is the central star of an old planetary nebula that underwent a very late thermal pulse a few years before its discovery in 1996. We have been monitoring the evolution of the optical emission line spectrum since 2001. The goal is to improve the evolutionary models by constraining them with the temporal evolution of the central star temperature. In addition the high resolution spectral observations obtained by X-shooter and ALMA show the temporal evolution of the different morphological components.
