This is particularly true for one particular kind of supernova known as Type Ia. An overview of the different proposed Type Ia supernova progenitors has been published on the arXiv preprint server.

Astronomers have discovered an extremely rare, high mass, compact binary star system only ~150 light years away. These two stars are on a collision course to explode as a type 1a supernova, appearing ...

A type Ia supernova occurs when a white dwarf draws hydrogen from a companion. But Sirius A and B are too widely separated ...

A nearby cosmic ticking time bomb has been found! Just 150 light years away, a pair of white dwarf stars are on a death ...

A unique dataset of Type Ia supernovae being released today could change how cosmologists measure the expansion history of the universe. Dr. Mathew Smith and Dr. Georgios Dimitriadis from ...

The work is published in the journal Physical Review Letters. A type Ia supernova occurs in a binary system in which one of the stars is a white dwarf. The primary mechanism behind this is ...

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 ...

Astronomers have confirmed a pair of white dwarfs on a collision course to become a type 1a supernova—the brightest cosmic ...

Type Ia supernovae originate in binary star systems—systems where two stars orbit each other. In one possible scenario, there are two stars approximately the same size—let's say about the size ...

Using dozens of type Ia supernovae, scientists discovered that the universe's expansion is accelerating. Roman will find tens of thousands, including very distant ones, offering more clues about ...

The NASA/ESA Hubble Space Telescope has captured a stunning image of SN 2022aajn, a Type Ia supernova in the constellation Gemini. Located 600 million light-years away, the explosion was first ...
