Magnetar magnetic fields peak between 1–2.5 x 10^14 Gauss

Researchers have found that 59 percent of young neutron stars, those less than 2,000 years old, detected in the Milky Way are either magnetars or central compact objects, challenging previous understandings of neutron star populations. Celsa Pardo-Araujo of the Institute of Space Sciences, CSIC, and colleagues used pulsar population synthesis to study magnetar birth rates, incorporating galactic evolution and spin-down effects. The work demonstrates the observed neutron star population requires a core-collapse supernova rate larger than two, and a magnetar fraction higher than previously estimated, suggesting current models may be undercounting both supernova events and magnetar births.
