Scientists Discover New ‘Pinwheel’ Star System

An international team of scientists has discovered a new, massive star system — one that also challenges existing theories of how large stars eventually die.

“This system is likely the first of its kind ever discovered in our own galaxy,” says Benjamin Pope, a NASA Sagan fellow at New York University’s Center for Cosmology and Particle Physics and one of the researchers.

Specifically, the scientists detected a gamma-ray burst progenitor system — a type of supernova that blasts out an extremely powerful and narrow jet of plasma and which is thought to occur only in distant galaxies.

“It was not expected such a system would be found in our galaxy — only in younger galaxies much further away,” adds Pope. “Given its brightness, it is surprising it was not discovered a lot sooner.”

The discovery of the system, reported in the journal Nature Astronomy and dubbed “Apep,” also included scientists from the Netherlands Institute for Radio Astronomy, the University of Sydney, the University of Edinburgh, the University of Sheffield, and the University of New South Wales.

The system, an estimated 8,000 light years away Earth, is adorned with a dust “pinwheel” — whose strangely slow motion suggests current theories on star deaths may be incomplete.

When the most massive stars in our universe near the end of their lives, they produce fast winds — typically moving at more than 1,000 kilometers per second — that carry away large amounts of a star’s mass. These fast winds should carry away the star’s rotational energy and slow it down long before it dies.

“These massive stars are often found with a partner, in which the fast winds from the dying star can collide with its companion to produce a shock that emits at X-ray and radio frequencies and produces exotic dust patterns,” explains Joseph Callingham, a postdoctoral fellow at the Netherlands Institute for Radio Astronomy and lead author of the paper.

“Apep’s dust pinwheel moves much slower than the wind in the system,” he adds. “One way this can occur is if one of the massive stars is rotating so quickly that it is nearly tearing itself apart. Such a rotation means that when it runs out of fuel and begins to explode as a supernova, it will collapse at the poles before the equator, producing a gamma-ray burst.”

Founded in 1995 – Earth Changes TV was born with Battros as its creator and chief editor for his syndicated television show. In 2003, he switched to a weekly radio show as Earth Changes Media. ECM quickly found its way in becoming a top source for news and discoveries in the scientific fields of astrophysics, space weather, earth science, and ancient text. Seeing the need to venture beyond the Sun-Earth connection, in 2016 Battros advanced his studies which incorporates our galaxy Milky Way - and its seemingly rhythmic cycles directly connected to our Solar System, Sun, and Earth driven by the source of charged particles such as galactic cosmic rays, gamma rays, and solar rays. Now, "Science Of Cycles" is the vehicle which brings the latest cutting-edge discoveries confirming his published Equation.
