Magnetars and fossil-field model of origin of magnetic field

TL;DR

This paper investigates the origin and evolution of magnetars, supporting the fossil-field model as the cause of their high magnetic fields and linking their formation to more massive stars.

Contribution

It provides new arguments favoring the magnetar model and demonstrates that these objects originate from more massive stars with fossil magnetic fields.

Findings

Magnetars are formed from more massive stars.

Fossil-field model explains their high magnetic fields.

New evidence supports the magnetar model.

Abstract

The evolution and genesis of Anomalous X-ray Pulsars and Soft Gamma ray Repeaters are investigated. The new arguments in favor of magnetar model are found. It is shown, that these objects are formed from more massive stars and responsible for their high magnetic fields is fossil-field model.
