Radio signal reveals supernova origin

Radio signal reveals supernova origin

Astronomers from the Oskar Klein Centre have revealed the origin of a thermonuclear supernova explosion thanks to the very first radio detection of the Type Ia-supernova. The results appear in the latest issue of the journal Nature.

The radio wave detection and strong helium emission lines reveal that supernova SN2020eyj was the result of a white dwarf exploding because it accreted too much matter from a companion helium star. Erik Kool from the Oskar Klein Centre and Stockholm University Astronomy Department is lead author on the paper. Other contributing OKC-affiliated researchers are Joel Johansson, Jesper Sollerman, Steve Schulze, Peter Lundqvist, Sheng Yang, and Conor Omand.

Oskar Benjamin Klein

was born in Stockholm the 15th of September 1894. He is the greatest Swedish theoretical physicist of the 20th century, and also an International authority on quantum mechanics in his time but even more recognised after his death for his pioneering work in several fields. Oskar Klein studied very fundamental theoretical questions.
