The Spirograph Nebula, or IC418, has been the subject of a new study that spans over 130 years of observations. Discovered in 1891, IC418 is notable for its intricate structure and has been closely monitored using various imaging techniques, including those from the Hubble Space Telescope. Researchers from the University of Manchester and Hong Kong University analyzed historical spectroscopic data, revealing that the central star's temperature has increased by 3000°C since its discovery. This rate of heating is faster than typical stars but still slower than predicted by stellar evolution models. The study also found that the star's original mass is about 1.4 times that of the sun, which is lower than expected for carbon-rich stars, suggesting that current models of carbon star evolution may need revision. The findings underscore the importance of historical astronomical data in enhancing our understanding of stellar life cycles.
