Researchers at the European Southern Observatory (ESO) have discovered a new type of star called a massive magnetic helium star, providing clues to the mysterious origin of magnetars. Magnetars are extremely dense dead stars with the strongest magnetic fields in the universe, but astronomers weren't sure how they form. Using several telescopes around the world, including ESO facilities, researchers have discovered a living star HD 45166 that is likely to become a magnetar.
HD 45166 has an extremely strong magnetic field of 43,000 gauss, making it the most magnetic massive star yet found. This planet has a magnetic field 100,000 times stronger than Earth's. This is the first observation of a massive magnetic helium star. The discovery of this new type of astronomical object helps unravel the understanding of the origin of magnetism.
The study creates a new understanding of HD 45166. Previous models could not explain its unusual behavior as one of a helium-rich pair of stars with a mass several times that of our Sun. The star's strong magnetism probably influenced its uncharacteristic behavior.
The calculations show that HD 45166 will end its life as a magnetar. As it gravitationally contracts, its magnetic field will strengthen, turning into a super-dense core with a field of about 100 trillion gauss - the strongest magnets in the universe.
The study also found that HD 45166 has a smaller mass than previously reported, twice the mass of the Sun. Its stellar companion is moving at a much greater distance than previously believed. HD 45166 probably formed from the merger of two smaller helium stars.
The discovery suggests that stars with strong magnetic fields can influence star development. It provides a vivid example of a star likely to become one of the most powerful magnetic objects in the universe. It opens a window into the mysterious origin of magnetars by revealing the star's stage in becoming a magnetar.
The insights open the door to future studies that will provide a better understanding of stellar magnetism, evolution and life after stellar death. This could improve knowledge of what enables or influences the formation of the universe's ultimate magnetic dynamo.
Two Israeli researchers also participated in the study: Dr. Tomer Shanhar - University of Amsterdam, Netherlands (now at the Center for Astrobiology in Madrid, Spain), and Prof. Avishai Gilkis - Faculty of Physics and Astronomy, Tel Aviv University.
Summary of the article:
Magnetars are a type of very dense neutron stars that are characterized by extremely strong magnetic fields.
Main Features:
- An extremely strong magnetic field whose strength can reach trillions of gauss, a million billion times stronger than the Earth's magnetic field.
- A rapid rotation around their axis that causes the acceleration of charged particles and the creation of a magnetic field.
- A diameter of only about 10-20 km, but a very large valve and may reach 2 times the mass of the Sun.
- Extremely high density of matter - much greater than the density of Earth's atoms.
- X-rays and other electromagnetic radiation are emitted as a result of the strong magnetic fields.
- Magnets are classified as pulsars if they rotate at high speed and emit regular electromagnetic pulses. They are common in dense star regions such as nebulae.
- Magnetars are an important source of information about extreme matter physics and the processes occurring in neutron stars.

Perhaps helium changes its properties when it is under such great gravity and compressed in such an extreme way
Maybe even turns into a liquid or a solid
All these pictures………in the era of AI creativity. Go find out how authentic the photos are or created using artificial intelligence….worth thinking….
The summary has more information than her letter.
in astronomy. They once wrote that they recorded the end of the universe that reached 13.8 billion light years. They once wrote that they recorded the oldest galaxy 12.8 light years. A few days ago they wrote that they recorded the most distant galaxy of 390 million light years. Please find the differences. And please find the cheaters.
A very strong magnet is found above the concentrations of the Maruks and causes them to be violent and screwed up and slaves of King Bibi. Because of the disruption of the electricity in the bit of brain they have.
He turned all the hydrogen into helium and other stuff but the helium is a pretty major component
What does the star helium mean?
If it is a star (not a planet), and is also expected to become a neutron star, why doesn't it have heavier elements? Or does the name "helium" not indicate its composition? So why is it called the "helium star"?
