Co-authored "UVBY Photometry of Blue Stragglers in NGC 7789" with Bruce A. Twarog

In 1985, Neil deGrasse Tyson co-authored a significant research paper with Bruce A. Twarog titled "UVBY Photometry of Blue Stragglers in NGC 7789", published in the Astronomical Journal, volume 90, page 1247. This study provided a comprehensive photometric analysis of blue stragglers within the open cluster NGC 7789, utilizing the UVBY photometric system. Blue stragglers are intriguing stellar objects that appear younger and more luminous than their counterparts in the same cluster, raising questions about their formation and evolutionary processes. The research aimed to understand the characteristics and distribution of these stars, contributing valuable insights into stellar evolution and the dynamics of star clusters. The findings from this study have implications for our understanding of stellar populations and the mechanisms that lead to the formation of blue stragglers.
