Supernova 289/46

Supernova 289/46 is the designation for a pair-instability supernova that occurred within the Alamtheria galaxy, it occurred within Alamtheria spatial grid 289, it was the forty sixth supernova observed in the region since the founding of the Alamtheria Sovereignty.

The SN289/46 supernova represented an anomalous event in that it had a spectrum unlike any previously observed supernova, and because a large portion of the progenitors mass simply disappeared.

The Supernova occurred in the earth year 2005, and remained the brightest single object within the Alamtheria galaxy for a total of three months.

Characteristics
The progenitor star to SN289/46 was Ermia 8-9, a hypergiant star with a mass 230 times that of the sun

A pair instability supernova can only occur in stars that are incredibly massive, having a range of 130 to 250 solar masses. Just before the end of Ermia 8-9’s life its core began to produce high energy gamma rays which had a greater energy than the rest mass of two electrons. These high energy gamma rays began to interact with atomic nuclei and were converted from energy into matter, disrupting the equilibrium between thermodynamic pressure and gravity within the stars core. The sudden drop in pressure caused the core to collapse; as the core collapses it became hotter and hotter until a runaway thermonuclear reaction began, within a few seconds all fuel within the core underwent a cataclysmic thermonuclear fusion reaction, blowing Ermia 8-9 completely apart while leaving only a debris cloud behind.

SN289/46 began with a spectrum fitting of a pair-instability supernova, however near the end of the event the spectrum suddenly changed into something completely unrecognizable. The Alamtheria Sovereignty sent a series of probes into the remains to gather more information. The probes reported that the remnant was only 155 solar masses, a far cry from the 230 solar masses of the progenitor star. The probes also discovered that the newly formed structure was hollow, with the core almost completely devoid of matter. At the time the consensus was that the supernova had produced enough energy to create a spatial rift. The missing mass had then travel through the rift causing it to collapse. The biggest flaw in this scenario is that the probes did not detect the distinctive signature of a spatial rift, and no corresponding rift was ever found. It was then proposed that the corresponding rift may have opened within a black hole, such as Angkor Askma, and that the large amount of mass-energy from the supernova could have masked the traces of a spatial rift.

It was recently proposed that the supernova had phased the missing material into interspace; such an event could easily explain the missing material, it would also explain why the center of the remnant is empty, more of the central material was phased into interspace. It could also offer an explanation for the existence of planets such as Phantos.
