The best indirect hint towards this suggestion is the recognition that some peculiarities in the Horizontal Branch (HB) stars distribution (blue tails, gaps, anomalous luminosity slope of the flat part of the HB) can be attributed to the larger helium abundance in the matter, processed through Hot Bottom Burning, from which these stars are born.

الحصول على السعرHere I present evidence that the bulge field RR Lyrae stars (pulsating horizontal branch stars) exhibit hot kinematics and null or negligible rotation and are therefore members of a separate population from the bar/pseudobulge. Gaia DR2 proper motions are used to investigate the RR Lyrae stars orbits.

الحصول على السعرHorizontal branch stars belong to an advanced stage in the evolution of the oldest stellar galactic population, occurring either as field halo stars or grouped in globular clusters.
الحصول على السعرMicroevolution is the change in allele frequencies that occurs over time within a population. This change is due to four different processes: mutation, selection (natural and artificial), gene flow and genetic change happens over a relatively short (in evolutionary terms) amount of time compared to the changes termed macroevolution which is where greater differences in the ...
الحصول على السعرA horizontal distance, specified by a horizontal parameter, determines the length of each branch of a node from the end of the tree. For example, if the horizontal distance is one inch, then the length of each branch in FIGS. 3,4 and 5 is one inch.
الحصول على السعرthe horizontal branch. Our calculations therefore provide the most uptodate set of stellar models applicable to all problems of globular cluster dating. In particular, we show for the rst time how particle di usion influences the evolution of lowmass stars until the end of the horizontalbranch phase.
الحصول على السعرThe globular cluster omega Centauri contains the largest known population of very hot horizontal branch (HB) stars. We have used the Hubble Space Telescope to obtain a farUV/optical colormagnitude diagram of three fields in omega Cen.
