A highly magnetized and rapidly rotating white dwarf as small …
Jun 30, 2021 · A binary star merger has produced a white dwarf with a spin period of under 7 minutes, a magnetic field of 600 to 900 million gauss and a radius only slightly larger than that of our Moon.
A magnetic massive star has experienced a stellar merger
Apr 11, 2024 · Frost et al. observed a binary massive star using interferometry and spectroscopy and found that one component is magnetic and appears to be younger than its companion. They argue that the system originally contained three or more stars and then experienced a merger that produced the magnetic star and made it appear younger.
A massive helium star with a sufficiently strong magnetic field
Aug 17, 2023 · Magnetars are highly magnetized neutron stars, the formation mechanism of which is unknown. Hot helium-rich stars with spectra dominated by emission lines are known as Wolf-Rayet stars. We observed the binary system HD 45166 using spectropolarimetry and reanalyzed its orbit using archival data.
