WebThe traditional H-R diagram plotting activity shows the different branches of the diagram and the location of giants, supergiants and white dwarfs – all part of the evolutionary track involving main sequence stars. However, it presents a rather static view of stellar evolution. WebRR Lyrae stars are powerful tracers of Galactic structure, substructure, accretion history, and dark matter content. The characteristic photometric variability of RR Lyrae stars makes it relatively easy to distinguish them from other objects, and they are excellent standard candles. In this paper, we report on the discovery of distant RR Lyrae stars, including …

WebDuring this stage of expansion, the star will move up and to the right on the HR diagram along the Red Giant Branch (RGB). A G (V)-class star such as our Sun may end up as a high-K or low-M giant.
