FfFfFfFF 58,113 Posted August 11, 2021 Share Posted August 11, 2021 Astronomers have inspected the brightest star of a globular cluster known as 47 Tucanae. Results of the study, published August 3 on arXiv.org, provide important insights into the properties and chemical composition of this star, what could improve our understanding of the cluster's nature. Located some 13,000 light years away in the constellation Tucana, 47 Tucanae, or 47 Tuc for short, is a globular cluster with a diameter of about 120 light years. It is the second brightest GC in the sky and can be seen with the naked eye. Although many studies of the bright star have been conducted, its chemical composition is still poorly understood. The observations allowed the team to determine photospheric abundances of 26 elements of the bright star. The data show that the intermediate-mass elements generally scale with iron, while the heaviest elements have roughly solar abundances. It was found that the star has a relatively low carbon to nitrogen ratio, what suggests that it belongs to the second generation of cluster stars. https://phys.org/news/2021-08-brightest-star-tucanae.html Link to post Share on other sites More sharing options...
Stupid Oreo 14,669 Posted August 11, 2021 Share Posted August 11, 2021 So impressive how they can determine the elements so far away by their nanometric wavelengths Link to post Share on other sites More sharing options...
