A kilonova (also called a macronova) is a transient astronomical event that occurs in a compact binary system when two neutron stars or a neutron star and a black hole merge. [1]

2023年7月10日 · Using the James Webb Space Telescope (JWST), astronomers have traced an incredibly bright gamma-ray burst (GRB) back to its source, a violent collision between two neutron stars. The ring on your...

2023年6月9日 · A kilonova is an explosion resulting from the collision of two neutron stars, or a neutron star and a black hole. These events are extremely energetic, and can release as much energy in a few seconds as our Sun will produce in its entire 10-billion-year lifetime.

2023年10月25日 · The highly sensitive infrared capabilities of Webb helped scientists identify the home address of the two neutron stars that created the kilonova: a spiral galaxy about 120,000 light-years away from the site of the merger.

2023年10月9日 · A kilonova is a bright blast of electromagnetic radiation that happens when two neutron stars or a neutron star and a stellar-mass black hole collide and merge.

2023年10月23日 · If Earth happens to be close to a kilonova, it would be very, very bad news for all of us. Fortunately, a recent study shows the kilonova risk is tiny.

2022年2月28日 · An artist’s conception illustrates the aftermath of a "kilonova," a powerful event that happens when two neutron stars merge.

2023年9月29日 · Kilonova is also a new term, coined to describe something first witnessed in 2017. Kilonovas involve two neutron stars orbiting around each other whose orbits decay to the point where they...

A more promising counterpart is the so-called “kilonova.” This transient is similar to a faint, short-lived supernova, but is powered by the radioactive decay of heavy r-process elements. There are many models that attempt to predict the observed behavior of a kilonova.
