Warning, Over-Hyped Title Alert: But It’s A Frackin’ SUPERNOVA!
"SuperNova" by Shadow-Trance (DeviantArt) I’m not kidding, last week was a huge mess of a supernova doomsday circus. It was like whispering “there’s a bomb under your chair” to the person next to you in a crowded theater and then watching the resulting flood of people...

Whatever Happened to Hyper-Velocity Star HD 271791?

Whatever Happened to Hyper-Velocity Star HD 271791?
One scenario: Exploding star flings binary parter away at high velocity (Max Planck Institute for Astrophysics) HC 271791 is a star with a problem, it’s moving so fast through our galaxy that it will eventually escape from the Milky Way all together. However, there is a growing question mark hanging...

Wolf-Rayet Star: My Favourite Stellar Object

Wolf-Rayet (WR) stars are my favourite stellar objects bar none. Due to the excitement factor I find them even more interesting than black holes, pulsars and quasars. Why? Well, they are a significant period of a massive star’s lifetime making its violent, self-destructive death, possibly culminating...

Collapsing Wolf-Rayet Stars and Inverse Compton Scattering of Stellar Photons

Wolf-Rayet stars are a violent and self-destructive phase of a massive star’s lifetime. This is the point at which they begin to die as a prelude to a supernova and black hole formation. Often, large nebulae can be found around these bright stellar objects (pictured), emitting strong ultraviolet...

Could a Wolf-Rayet Star Generate a Gamma Ray Burst?

Gamma ray bursts (GRBs) are the most energetic events to be seen in the observable universe. On March 19th, a record breaking GRB was observed in the constellation of Boötes by NASA’s Swift Observatory and ground based telescope arrays (i.e. the Polish “Pie of the Sky” GRB detector)....
