论文摘要
在这项工作中，我们介绍了新的南部S型共生星的发现和表征，Degape 35。我们获得了低分辨率的光谱观察结果，并用Gaia DR3和其他调查的光度计补充了它们。该目标的光谱显示出突出的发射线，包括高度电离[Fe VII]和O VI线。该共生二进制的凉爽成分是一个M4-5巨人，有效温度〜3 380-3 470 K，发光度〜3 000 l $ _ \ odot $（用于3 kpc的距离）。热组件是燃壳的白矮人。 Gaia卫星的光度观测结果最近在Gaia DR3上发表，这表明我们暂时归因于二进制的轨道运动的周期约为700-800天。
In this work, we present the discovery and characterization of a new southern S-type symbiotic star, DeGaPe 35. We have obtained the low-resolution spectroscopic observations and supplemented them with photometry from Gaia DR3 and other surveys. The optical spectra of this target show prominent emission lines, including highly ionized [Fe VII] and O VI lines. The cool component of this symbiotic binary is an M4-5 giant with effective temperature ~ 3 380 - 3 470 K and luminosity ~ 3 000 L$_\odot$ (for the adopted distance of 3 kpc). The hot component is a shell-burning white dwarf. The photometric observations of the Gaia satellite, published recently in the Gaia DR3 suggested the variability with the period of about 700 - 800 days that we tentatively attributed to the orbital motion of the binary.
