SUMMARY:Introduction to Astronomy September 2021
DESCRIPTION:Open & Globular Star Clusters\nSo Different but so Similar\nBy Chris Benton \n  \nAim – To compare & contrast features of open & globular star clusters discussing their differences & similarities \nOpen star clusters\, situated in star-forming regions of galaxies\, are relatively small groups of young stars loosely gravitationally bound. In contrast\, globular clusters are large groups of old stars tightly gravitationally bound into compact spherical objects and usually observed in the stellar halos of galaxies. \nDuring this online presentation\, Chris Benton discusses these features that make the two types appear so different\, how pressure density waves propagate through galactic disks to trigger star formation\, followed by new ideas on how globular clusters form. You will then see how these two distinct star clusters test theories of stellar evolution and may represent two extremes of the same object created through similar physical processes. \nWe look forward to seeing you all on our YouTube website to view this online using the below link. \nhttps://www.youtube.com/c/AucklandAstronomicalSociety \nBest regards \nThe AAS Team
