On a New Parameter to Estimate the Helium Content in Old Stellar Systems
... ABSTRACT. We introduce a new parameter Δξ— the difference in magnitude between the red giant branch (RGB) bump and the point on the main sequence (MS) at the same color as the bump (which we call the “ benchmark ” ) — to ...

The HST/ACS Coma Cluster Survey V Compact stellar systems in the Coma Cluster
... In Fig. 9, we present the Faber & Jackson (1976) relation for a compilation of hot stellar systems. For elliptical galaxies, we take data from Faber et al. (1989), Geha, Guhathakurta & van der Marel ...

Chemical composition of the stellar cluster Gaia1: No surprise behind Sirius

Weighing the two stellar components of the Galactic bulge
... The second misconception is that the MP, spheroidal compo- nent represents a minor contribution to the total stellar mass of the bulge. This idea is based on the fact that in Baade’s Window, by far the most ...

Discovery of a thin stellar stream in the SLAMS survey
... Thin stellar streams in the Galactic halo may provide the first evidence for such a population, the basic idea being that a subhalo interaction can induce an observable density perturbation – a gap – in the ...
