Briefings

A new arXiv preprint investigates how magnetars form, noting that two neutron stars touching could create one. The study highlights that magnetars possess magnetic fields 1,000 times stronger than typical ones, potentially causing transient events like soft gamma-ray repeaters. The research is currently unpublished and subject to peer review.

Key points

• Magnetars are neutron stars with magnetic fields 1,000 times stronger than typical ones, capable of generating powerful transient events.
• The study proposes that two neutron stars colliding could result in a single magnetar formation.

Context

Magnetars are rare neutron stars with extreme magnetic fields, likely responsible for gamma-ray bursts. This preprint explores their formation mechanisms, specifically the collision scenario of two neutron stars.

Limitations

The study is an arXiv preprint and not yet peer-reviewed. Data on magnetic field strengths and collision dynamics are observational estimates without direct measurement confirmation.
