The exploding stars known as Type Ia supernovae serve an important role in measuring the universe, and were used to discover the existence of dark energy. They’re bright enough to see across large ...
Researchers have found white dwarf stars with masses close to the maximum stable mass (called the Chandrasekhar mass) are likely to produce large amounts of manganese, iron, and nickel after it orbits ...
Type Ia supernovae are stellar explosions used to measure the universe's expansion. These explosions result from white dwarfs exceeding a critical mass, causing them to reignite and explode. Two ...
So, instead, supernovae are categorized by observed characteristics such as the light curves of how they brighten and fade ...
The 2-m aperture Chinese Space Station Telescope (CSST), which observes at wavelengths ranging from 255 to 1000 nm, is expected to start science operations in 2024. An ultra-deep field observation ...
Supernovae, categorized as Type I (low hydrogen) and Type II (high hydrogen), produce varying abundances of heavy elements. Type Ia supernovae, resulting from thermal runaway in white dwarfs, are rich ...
Scientists have turned to artificial intelligence (AI) to better understand why some dead stellar remnants called white dwarf stars explode. These energetic explosions, called Type Ia supernovas, ...
A team of astronomers has discovered the fastest optical flash of a Type Ia supernova, and reports a study in the Astrophysical Journal Letters published on December 8. Many stars end their lives ...
This is a movie of the explosion of a double white dwarf binary star system. The simulation was published in Nature Astronomy by James Munday and collaborations in LINK. Full credit goes to Dr.
“The explosions of white dwarfs play a crucial role in astronomy,” said Priyam Das, a study co-author and PhD student at the University of New South Wales Canberra, Australia. “Yet, despite their ...
Ironically, to study dark energy — a murky, unknown something that seems to act as an accelerant for our universe’s expansion — astronomers rely on brilliant supernovae. From 2013 to 2019, the Dark ...
Astronomers find an explanation for the fastest stars in the galaxy while uncovering a new mechanism for a supernova explosion. Credit: Technion illustration Astronomers call a special kind of ...
