The red clump is a clustering of red giants in the Hertzsprung–Russell diagram at around 5,000 K and absolute magnitude (M V) +0.5, slightly hotter than most red-giant-branch stars of the …

Low-mass stars in their core-helium-burning stage define the sharpest feature present in the color-magnitude diagrams of nearby galaxy systems: the red clump (RC). This feature has …

2024年12月18日 · 红团簇星 是 赫罗图 上的红巨星聚类，它们的表面温度约为5,000K， 绝对星等 （M V）+0.5，比大多数具有相同亮度的 红巨星分支 星稍热。 它被视为红巨星分支的较稠密区 …

红群聚（Red Clump）是 恒星 在 赫罗图 上的一个区域，它被认为富含金属的恒星。 与 主序带 上表面温度相同的恒星比较，它的 亮度 是比较高的 (或是与相同亮度的恒星比较，它的表面温度 …

2022年1月20日 · 在赫罗图上，分布在温度约4000～5000K且光度约50～80倍太阳光度范围内的恒星聚团。

Primary red clump (RC) stars are metal-rich low-mass stars of intermediate to old age in the core helium-burning phase (ignited degenerately). They are widely used as distance indicators given...

2009年8月28日 · We can clearly identify the bulk of the red giants observed by CoRoT as red-clump stars, i.e. post-flash core-He-burning stars. The distribution of $\nu_{max}$ and of …

Galactic bulge/bar are the red clump stars: they are very numerous, sufficiently bright to be detected throughout the bulge, and their absolute I-magnitude has an intrinsic dispersion of …

Low-mass stars in their core-helium-burning stage define the sharpest feature present in the color-magnitude diagrams of nearby galaxy systems: the red clump (RC). This feature has …

2022年2月18日 · Although red clump (RC) stars are easy to identify due to their stability of luminosity and color, about 20-50% are actually red giant branch (RGB) stars in the same …
