Scientists have discovered a weak supernova in the Milky Way.

Not all supernovas are created equal. These star-death explosions are frequently extraordinarily energetic. But occasionally they are a total dud.

A big star that had so much of its material sucked off by the gravitational pull of a companion star in a stellar union known as a binary system was described by scientists on Wednesday. By the time the massive star finally exploded at the end of its life cycle, it could hardly manage a whimper.

The collapsed star, which is now an extraordinarily dense object known as a neutron star, is still in a subdued circular orbit with its partner because the final explosion was so mild.

Clarissa Pavao, a physics undergraduate student at Embry-Riddle, who co-authored the study, described the explosion as “faint, delicate, and passive.”

These two stars are headed toward one another.

Their detonation will yield gold.

This kilonova occurrence has astronomers intrigued because it may provide answers to their questions about how kilonovae form and the beginnings of the universe’s strongest components.

It is approximately 11,000 light-years away from Earth. The Neil Gehrels Swift Observatory of Nasa was the first to discover the system. This kilonova occurrence has excited astronomers.The first star system that will ever form a kilonova—a super-potent explosion that produces gold—has been found by astronomers.

One of the universe’s most powerful explosions will result from the collision of the two neutron stars, which are currently on a collision track.

“The orbit would not be circular if there was more of an explosion,” Richardson added.
“A typical supernova may significantly alter the orbit but wouldn’t necessarily destroy the companion.
For instance, it might give the system a kick that causes the orbit to become much more elliptical or even sends the neutron star and the remaining star on swift paths that could even expel them from the galaxy.

In a Milky Way with between 100 and 400 billion stars, just 10 of the type of binary systems under study are thought to exist.

Only 10 such systems have been found in the depths of the universe, which makes this discovery incredibly rare.
The binary star system was discovered by astronomers at Cerro Tololo Inter-American Observatory in Chile using the SMARTS 1.5-meter Telescope.
An ultra-stripped supernova gave rise to a high-mass X-ray binary.

An ultra-stripped supernova gave rise to a high-mass X-ray binary.
Because they exhibit little to no ejecta from the actual supernova event1,2, ultra-stripped supernovae vary from other terminal explosions of big stars.
After the exploding star has lost its surface due to interactions with its companion, they are predicted to happen in huge binary systems. Read full news or join the discussion now in this forum
