Having examined the star’s temperature and mass, scientists estimate that the partial supernova occurred some 40 million years ago.
A peculiar star hurtling through our galaxy may have been set on its course by a “partial” supernova event, Space.com reports, citing a new study.
The star, a white dwarf with a relatively low mass for its kind, was first discovered in 2015 and is located about 1,430 light years from Earth, with the study noting that this celestial body is traveling at a speed of about 900,000 kilometers per hour “in the opposite direction of the way the galaxy is rotating”.
According to the media outlet, the star’s traits led researchers to believe that it underwent a “partial supernova” which may have lasted “maybe a couple of hours”, as Gänsicke put it.
Based on the star’s mass and temperature, scientists estimate that this probable partial supernova event took place about 40 million years ago.
