So, instead, supernovae are categorized by observed characteristics such as the light curves of how they ... particular kind of supernova known as Type Ia. An overview of the different proposed ...

ABSTRACT A comparative study of near–maximum‐light optical spectra of 24 Type Ia supernovae (SNe Ia) is presented. The spectra are assigned to four groups. Seven “core‐normal” SNe Ia have very similar ...

The event will be ten times brighter than our Moon in the night sky, but never fear, it won't happen for another 23 billion years ...

We also examine the effects of reddening on the K‐corrections and the light curves of Type Ia supernovae. Finally, we provide a few examples of how these techniques affect our current understanding of ...

Two white dwarfs are trapped in a decaying orbit that will eventually turn them into a Type Ia supernova. It’s a common ...
