Never had a death been so dazzling. A star had been found to explode approximately 1.3 billion years in the past with such intensity, that it had shone 50 times more brightly as compared to a combination of the billions of stars existing in the host galaxy. Such was it brightness, that it could’ve been seen by the naked human eye, without any other device, had it happened on the Andromeda Galaxy. The outburst has officially been termed as PTF10hgi, It is classified as a part of a rare and extremely unique category of explosions, which are termed as “superluminous” supernovae. Such explosion has the ability to shine up to 100 times brighter as compared to typical ones. However, astronauts have been unable to attribute a cause to this phenomenon as of yet.
A hypothesis is of the opinion that magnetars – ultadense are powering these explosions and are rapidly spinning as well as heavily magnetized cinders comprising stellar cores which can be formed as a result of explosions of supernova. If these magnetars spin fast enough, for example 1,000 times in a second, they might rapidly slow down, while a magnetized wind is released in the process. This wind is created at the moment of formation of the magnetar and consequently shocks ejecta and adds constantly increasing amounts of light and heat to this explosion in the span of a few weeks, thereby making it way more luminous in comparison to usual standards.
However, this is only conjectural hypothesis. According to Brian Metzger, the essential piece of information that they’re missing is any form of confirmation of there being a magnetar at the explosion’s center, via direct observation. Metzger is currently working at the Columbia University as an astronomer at Columbia University. Recently, a plausible solution to this question may have been provided by a new study that was posted to arXivlate, which is a preprint server.
