摘要:

银河星团的精确距离(<10%)允许精确估计任何物理关联的行星状星云(PN)及其中心恒星(CSPN)和其祖先的物理参数。它的质量可以与PN的化学特性相关联,并且为广泛使用的白矮星(WD)初始到最终质量关系(IFMR)提供了额外的数据,IFMR对于追踪整个星系中碳和氮的发展至关重要。到目前为止,只有一个PN(PHR 1315 - 6555)被证实与银河系疏散星团(ESO 96 -SC 04)有物理联系,其关闭质量为$\sim$ 2 M $_{\odot}$。我们的深HST测光用于搜索这个目前唯一的PN的CSPN。在这项工作中,我们提出了我们的结果。

英文摘要:

Accurate (<10%) distances of Galactic star clusters allow precise estimation of the physical parameters of any physically associated Planetary Nebula (PN) and also that of its central star (CSPN) and its progenitor. The progenitor's mass can be related to the PN's chemical characteristics and furthermore, provides additional data for the widely used white dwarf (WD) initial-to-final mass relation (IFMR) that is crucial for tracing the development of both carbon and nitrogen in entire galaxies. To date there is only one PN (PHR1315- 6555) confirmed to be physically associated with a Galactic open cluster (ESO 96 -SC04) that has a turn-off mass $\sim$2 M$_{\odot}$. Our deep HST photometry was used for the search of the CSPN of this currently unique PN. In this work, we present our results.
