A new observation about WR or Wolf-Rayet stars is that they can transform into magnetars.

 A new observation about WR or Wolf-Rayet stars is that they can transform into magnetars. 


The magnetars and WR stars are things that interest fusion developers. The high-energy blue stars can give tips on how to keep high-energy plasma steady in fusion reactors. The WR stars can also give tips for making new types of plasma-based magnets that can be used to control plasma in fusion reactors. 

Wolf-Rayet stars are blue supergiants formed of helium. The Wolf-Rayet stars are extremely strong magnetic fields and they are extremely hot. There is a model that some magnetars, lightweight neutron stars with extremely powerful magnetic fields can have origin as Wolf-Rayet stars. When magnetic power lines of Wolf-Rayet stars are traveling around its core magnetic fields harvest energy. Mainly that energy comes from WR star. But some part of that energy comes from WR Star's entirety. 

In this model is a possibility, that the magnetic field around the WR star becomes more and more powerful. And it can press the plasma of the WR star into the magnetar. In that model, the magnetic field acts like a powerful press. A powerful magnetic field crushes the WR star into a neutron star. In that model, the transformation of the WR star into magnetar doesn't always require a supernova explosion.

Intense winds of particles blowing away from the star are trapped by this magnetic field, enshrouding the star in a gaseous shell as illustrated here. Credit: ESO/L.

During this explosion, its core will contract, trapping and concentrating the star’s already daunting magnetic field lines. Credit: NOIRLab/AURA/NSF/P. Marenfeld/M. Zamani".

But normally WR stars will explode when they turn into magnetars. The high-power radiation decreases the mass of the WR star very fast. And that means the origin of the WR star could be a very large star. But high power radiation can increase its mass very fast. And that means its fate could be different than predicted. 

"New findings centered on observations and stellar evolution models of a hot, helium-rich Wolf-Rayet star suggest that it is set to produce a magnetar when it undergoes a supernova explosion. These findings present a deeper understanding of the formation process of magnetars, which are considered the most magnetic entities in the Universe".

WR star is an extremely hot, blue helium star. The high energy radiation in that star pushes quantum fields around it away. That causes a situation. Where energy starts to flow out from WR star faster than usual. And that causes the expansion of the WR star. Expansion decreases the power of the nuclear reaction. That decreases the radiation pressure. And the quantum field drops back in. And that thing increases energy production. That cycle causes rings around the WR star.

The star Wolf-Rayet 140 sends strange energy waves around the universe.


Above: Wolf-Rayet 140 with its material rings. 

There is a strange fingerprint around the star Wolf-Rayet 140. That star produces circles of shockwaves around it. Those shockwaves are visible in the James Webb-telescope images. 

The Wolf-Rayet 140 is a very hot star. Its surface temperature is about 20 000 Kelvin. And maybe that thing is the reason why that star sends those waves around the universe. The energy production in this star is very powerful. And there is the possibility that changes in energy production are more visible than in so-called "normal stars".

The Wolf-Rayet 140 is 5000 ly. away from Earth. That star is two stars that are orbiting each other. And there is the possibility that those dust rings are forming when the star that orbits the rare Wolf-Rayet star pulls material from the surface of the central star. Then that orbiting star impacts that material that increases its energy production. But there is another theory about the form of those rings. 

Every star has a cyclic sequence. When a star produces energy that energy pushes its core or surface outward. And when the pressure in the nucleus of the star decreases. Its energy production decreases. And the surface of the star starts to fall to the middle of the star. 

 So whenever a star expands because of its energy production it stops that expansion. When the surface of the star turns to fall in. That effect can cause a situation where the cloud of ions would remain over the star. And when energy production in the star's nucleus increases. That radiation pushes those ions to a longer distance. 

That thing pushes radiation to that ion layer. When radiation decreases the ions send the radiation impulse. And then that ion layer will send energy impacts to the universe. So maybe that thing would explain why Wolf-Rayet 140 sends those energy waves to the universe. 

When we are thinking about extremely hot stars like Wolf-Rayet 140. There is a theory about the form of that kind of star. In that theory, the energy that comes from the nucleus of the star, along with its gravitational field makes it possible for the extremely hot and bright star locks the electrons in its plasma to a certain position. 

That thing would be an incredible thing if it's right or true. And that thing could be possible in cases where the radiation and gravitational fields of the star are much more powerful than regular giant stars. That thing turns those electrons and atoms' nuclei into the quantum-size antennas that are driving radiation away from the star differently than in smaller and cooler stars.

Could a graviton be a low-energy photon?

Image of a photon. We can think of gravity as forming when particles or objects spin. That spin binds energy from around it. That spin turns...
