The ultracompact X-ray binary X1850–087, located in the globular cluster NGC 6712, is a persistent atoll-type X-ray source that has previously shown unusual radio-continuum variability. Here we present the results of a pilot radio …

WebHowever star clusters that are both in a collisional dynamic regime and contain N >106 particles are a common occurrence, even in our Galaxy (see the discussion in Di Cintio et al. 2024). Direct N-body models of these star clusters cannot be simulated using a one-to-one star to stellar-particle ratio, due to the com-putational constraints of ...

WebApr 10, 2024 · The fact is that a typical globular cluster consists of stars formed at about the same time and containing a small amount of heavy elements. However, NGC 2419 is an exception to this rule. Hubble measurements have shown that the globular cluster contains two separate populations of red giant stars, and one of them is unusually rich in helium. WebAn important use of galactic clusters is the study of the age dependence of the metallicity of the stars in the galactic disk. There are several elements for which it is especially …
