Astronomers have employed the James Webb Space Telescope (JWST) to study the Small Magellanic Cloud, aiming to identify the number of binary stars present. This research is intended to aid in understanding the universality of the initial mass fraction (IMF) of galaxies. Binary stars can complicate measurements of the IMF due to their combined mass effects, so discerning them is crucial. The study represents an effort to improve accuracy in astrophysical observations related to star populations in other galaxies.
