What is a globular cluster? An observational perspective

R Gratton, A Bragaglia, E Carretta, V D'Orazi… - The Astronomy and …, 2019 - Springer
Globular clusters are large and dense agglomerate of stars. At variance with smaller clusters

On the triple origin of blue stragglers

HB Perets, DC Fabrycky - The Astrophysical Journal, 2009 - iopscience.iop.org
Blue straggler stars (BSSs) are stars observed to be hotter and bluer than other stars with
the same luminosity in their environment. As such they appear to be much younger than the …
