When two neutron stars collide, very bad things happen

Kilonova explosions from neutron star collisions may damage atmospheres and threaten life if nearby, according to a new study.

Non solo esplosioni di supernove. Scoperto un nuovo tipo di esplosione stellare, la millinova è cento volte più luminosa del Sole. Si allunga la lista delle esplosioni stellari: dopo le più celebri nova, supernova e kilonova, ora arriva anche la millinova, una nuova tipologia cento volte più luminosa del Sole ma circa mille volte meno di una classica nova.

First Kilonova Progenitor System Identified - Astronomers using the SMARTS 1.5-meter Telescope uncover a one-in-ten-billion binary star system

Astronomers using data from the SMARTS 1.5-meter Telescope at the Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF's NOIRLab, have made the first confirmed detection of a star system that will one day form a Kilonova — the ultra-powerful, gold-producing explosion created by merging neutron stars. These systems are so phenomenally rare that only about 10 such systems are thought to exist in the entire Milky Way.

Kilonova Discovery Challenges our Understanding of Gamma-Ray Bursts - International Gemini Observatory probes aftermath of gamma-ray burst and uncovers surprising evidence of colliding neutron stars

While studying the aftermath of a long gamma-ray burst (GRB), two independent teams of astronomers using a host of telescopes in space and on Earth, including the Gemini North telescope on Hawai‘i and the Gemini South telescope in Chile, have uncovered the unexpected hallmarks of a Kilonova, the colossal explosion triggered by colliding neutron stars. This discovery challenges the prevailing theory that long GRBs exclusively come from supernovae, the end-of-life explosions of massive stars.

Nova vs Supernova

#Supernova is the last dying gasp of a star as it goes dark.

A #nova, on the other hand, requires two stars. One star is always a white dwarf, while the other is usually a red giant.

#Hypernovas are supernovas that achieve a certain size and brightness. Usually, they're about 10 or more times brighter than a standard supernova. Another type, an extremely rare #kilonova occurs when two neutron stars collide, releasing an incredible gravitational wave.

Wat is een kilonova?

Een kilonova is een heldere explosie van elektromagnetische straling die optreedt wanneer twee neutronensterren of een neutronenster en een zwart gat met stellaire massa botsen en samensmelten.
