# Young neutron stars with soft gamma ray emission and anomalous X-ray pulsar

## TL;DR

This paper explores the energy sources of soft gamma repeaters and anomalous X-ray pulsars, comparing magnetar models with an alternative nuclear energy hypothesis in low-mass neutron stars.

## Contribution

It analyzes the magnetar model and proposes an alternative nuclear energy source in low-mass neutron stars for explaining SGR/AXP emissions.

## Key findings

- Magnetar model has observational inconsistencies.
- Nuclear energy in superheavy nuclei offers an alternative explanation.
- The paper discusses implications for neutron star energy mechanisms.

## Abstract

The observational properties of Soft Gamma Repeaters and Ano\-malous X-ray Pulsars (SGR/AXP) indicate to necessity of the energy source different from a rotational energy of a neutron star. The model, where the source of the energy is connected with a magnetic field dissipation in a highly magnetized neutron star (magnetar) is analyzed. Some observational inconsistencies are indicated for this interpretation. The alternative energy source, connected with the nuclear energy of superheavy nuclei stored in the nonequilibrium layer of low mass neutron star is discussed.
