The 'magnetorotational hypernova? is the phenomenon involving the explosion of a spinning star with a strong magnetic field. According to a research, the heavy metals detected in SMSS J2003-1142 were produced because of the magnetorotational hypernova. Earlier, it was believed that the neutron star mergers were the only way to produce elements that are heavier than zinc.
SMSS J2003-1142 is a 13-billion year old star located at the halo of the Milky Way. It was discovered by SkyMapper Telescope in 2018. It is unique as it is a metal poor star having more heavy metal elements than other stars of the same age.
