Red Clump Stars

Annual Review of Astronomy and Astrophysics, 2016
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 ...

Characterisation of the Gaia Red Clump

EAS Publications Series, 2014
Red Clump (RC) stars are known to be good distance indicators. However the accuracy on these calculations strongly depends on the knowledge of their basic properties: a complete calibration is required.

Ensemble seismology of Red Clump stars

Stars in the Red Clump (RC) are high-metallicity, low-mass, core-helium burning stars which went through the He-flash. They are astrophysically  important, since they can be used as standard candles that trace the chemical evolution of the Galaxy. Yet, due to the many uncertainties associated with the physical processes that happen during the helium ...

Chemical Properties of the Hipparcos Red Clump

2011
Hipparcos data have allowed the identification of a large number of clump stars in the solar neighbourhood. We discuss our present knowledge of their distributions of metallicities, CNO abundances, carbon isotope ratios and memberships of the first ascent giants and helium-core-burning stars.

Calibration and characterisation of the Gaia Red Clump

Proceedings of the International Astronomical Union, 2017
AbstractWe present new empirical Colour-Colour and Effective Temperature-Colour Gaia Red Clump calibrations. The selected sample takes into account high photometric quality, good spectrometric metallicity, homogeneous effective temperatures and low interstellar extinctions. From those calibrations we developed a method to derive the absolute magnitude,
