Red Clump stars in the Boötes III stellar system [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2009 Abstract We report on the detection of a population of Red Clump (RC) stars probably associated with the recently discovered stellar system Boötes III. The RC is identified as a 3σ peak in the luminosity function (LF) of colour-selected stars extracted from the Sloan Digital Sky Survey data base.

Multiple Stellar Populations along the Red Horizontal Branch and Red Clump of Globular Clusters [PDF]
The Astrophysical Journal, 2021 Abstract We exploit multiband Hubble Space Telescope photometry to investigate multiple populations (MPs) along the red horizontal branches (HBs) and red clumps of 14 metal-rich globular clusters (GCs), including 12 Milky Way GCs and the Magellanic Cloud GCs NGC 1978 and NGC 416.

CHEMICAL AND DYNAMICAL EVOLUTION IN THE SOLAR NEIGHBOURHOOD
Odessa Astronomical Publications, 2017 We measure the surface mass density of the galactic disk in the solar neighbourhood using two samples of red clump stars, we also determine the thin and thick disk chemical properties. High resolution spectral data of red clump stars towards the NGP have

The abundances of nearby red clump giants [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 Abstract Based on the analysis of high-resolution spectra with a high signal-to-noise ratio, we have determined the abundances of the α-elements O, Si, Ca and Ti, the iron peak elements V, Fe and Ni, and the heavy element Ba without the consideration of non-local thermodynamic equilibrium (NLTE) effect and the light neutron-rich elements

Age, Metallicity, and the Distance to the Magellanic Clouds From Red Clump Stars [PDF]
, 1998 We show that the luminosity dependence of the red clump stars on age and metallicity can cause a difference of up to < ~0.6 mag in the mean absolute I magnitude of the red clump between different stellar populations.

Reinforcing the link between the double red clump and the X-shaped bulge of the Milky Way [PDF]
, 2015 The finding of a double red clump in the luminosity function of the Milky Way bulge has been interpreted as evidence for an X-shaped structure. Recently, an alternative explanation has been suggested, where the double red clump is an effect of multiple ...

Asteroseismology of KIC 8263801:Is it a member of NGC 6866 and a red clump star? [PDF]
, 2018 We present an asteroseismic analysis of the Kepler light curve of KIC 8263801, a red-giant star in the open cluster NGC 6866 that has previously been reported to be a helium-burning red-clump star.

Red giant clump in the Tycho-2 catalogue [PDF]
Astronomy Letters, 2008 The Tycho-2 proper motions and Tycho-2 and 2MASS photometry are used to select 97348 red giant clump (RGC) stars. The interstellar extinction and photometric distance are calculated for each of the stars. The selected stars are shown to form a selection-unbiased sample of RGC stars within about 350 pc of the Sun with the addition of more distant stars.
