Article Synopsis
- Magnetars are super-strongly magnetized neutron stars, and their formation is not fully understood.
- Researchers studied the binary system HD 45166 and discovered it contains a Wolf-Rayet star with a mass of 2 solar masses and a magnetic field of 43 kilogauss.
- They suggest that this Wolf-Rayet star, due to its heavy mass and strong magnetic field, will likely explode as a supernova and leave behind a magnetar remnant, possibly formed from the merger of two smaller helium stars.
Ultra-stripped supernovae are different from other terminal explosions of massive stars, as they show little or no ejecta from the actual supernova event. They are thought to occur in massive binary systems after the exploding star has lost its surface through interactions with its companion. Such supernovae produce little to no kick, leading to the formation of a neutron star without loss of the binary companion, which itself may also evolve into another neutron star.
