Period Changes of RR Lyrae Stars in the LMC Globular Cluster NGC 2257
Published online by Cambridge University Press: 04 August 2017
Extract
The period changes of RR Lyrae stars can be compared with models of horizontal branch stars as a means of investigating the physical properties of the stars themselves, and of the stellar systems in which they are found (Smith and Sandage 1981). The present study is the first in which period change rates of extragalactic RR Lyraes have been estimated.
