An article to be published in “The Astrophysical Journal” reports a study on supernova remnants cataloged as Sagittarius A East, or simply Sgr A East. A team of researchers used observations conducted with NASA’s Chandra X-ray Observatory and the VLA radio telescope to study those remnants and concluded that they were generated by a rare type of supernova, the type Iax. The results can help astronomers understand the different ways a white dwarf can explode.
