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 same luminosity. It is visible as a denser region of the red-giant branch or a …

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 given rise to a series of methods aimed at measuring the distributions of stellar distances and extinctions, especially in the Magellanic Clouds and Milky Way Bulge.

May 28, 2024 · Explore the fascinating world of Red Clump stars, their characteristics, evolution, and crucial role in measuring cosmic distances and understanding galactic structures. Red Clump (RC) stars are an important class of stellar objects in astrophysics, known for their distinct position in the Hertzsprung-Russell (H-R) diagram.

Jul 27, 2018 · The discovery of the double red clump — two groupings of stars seen in the color-magnitude diagram of the galactic bulge — has raised questions about the structure and formation history of the stars surrounding the center of our galaxy.

Although red clump (RC) stars are easy to identify due to their stability of luminosity and colour, about 20-50 per cent are actually red giant branch (RGB) stars in the same location on the HR diagram.

Mar 21, 2022 · Red clump (RC) stars are low-mass stars in the stage of core helium burning (Cassisi & Salaris 1997). They are close to the first-ascent red giant branch (RGB) and have sizable convective envelopes resulting from a significant buffer of mass (a few 0.1 M ⊙ ) above the hydrogen-burning shell (Girardi 2016 ).

Nov 30, 2017 · Red clump (RC) stars are common stars, once similar to the sun, that have evolved into red giants now supported by helium fusion in their cores. Independent of their exact age or composition, all RC stars end up having about the same absolute luminosity.

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 given rise to a series of methods aimed at measuring the distributions of stellar distances and extinctions, especially in the Magellanic Clouds and Milky Way Bulge.

Jul 13, 2020 · When the rapid rotators reach the RGB, they develop a convective envelope while still spinning fast, and they keep having a significantly large rotation (v sin i ≥ 10 km s −1) during the subsequent core-helium-burning stage, also known as the red clump (RC) in reference to the color-magnitude diagram (e.g., Girardi 2016).

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 same luminosity. It is visible as a denser region of the red-giant branch or a …
