Jakarta, CNBC Indonesia – A study found that star carcasses release enormous amounts of energy. Dead stars, called pulsars, release gamma ray energy reaching 20 tera-electronvolts or ten trillion times the energy of light.

“That’s about 200 times more energetic than all the radiation ever detected before,” said co-author from North-West University, Christo Venter, quoted from Eureka AlertMonday (9/10/2023).

For information, pulsars are the remains of animals that exploded massively in supernovas. This explosion will leave behind a small dead star 20 kilometers in diameter which will have rapid rotation and a large magnetic field.

Pulsars will also emit rotating beams of electromagnetic radiation. If the beam enters the solar system, Earth can see the flash at regular intervals.

This Vera pulse is in the southern sky in the constellation Vela. It is the brightest pulsar in the electromagnetic spectrum and the brightest cosmic gamma ray in giga-electronvolts (GeV) rotating 11 times per second.

Research leader from the Astroparticle & Cosmology (APC) laboratory in France, Arache Djannati-Atai, explained that his team’s findings challenged previous knowledge. He also said there needed to be a rethink about how it works.

“The traditional scheme of particles accelerating along magnetic field lines inside or slightly outside the magnetosphere cannot explain our findings,” he explained.

“Are we witnessing the acceleration of particles through a process of magnetic reconnection on the outside of the light cylinder, which still maintains its rotation pattern? But with this scenario it is still difficult to explain how extreme radiation can be produced.”

Djannati-Atai explained that his findings had opened the way to new observations. Namely, to detect other pulsars with a more sensitive telescope.

“So it can pave the way for understanding the process of extreme acceleration for magnetized astrophysical objects,” he said.
