Oscillation: The Key For Understanding Strange Radio Behaviors Of AXP/SGRs

TL;DR

This paper proposes that stellar oscillations explain the unusual radio behaviors of AXP/SGRs, suggesting oscillations activate or enlarge radio emissions within quark star and magnetar models, with emissions fading as oscillations damp.

Contribution

It introduces the idea that stellar oscillations are key to understanding AXP/SGR radio behaviors in both quark star and magnetar frameworks.

Findings

Oscillations activate radio emission by crossing the death line.

Oscillations enlarge the radio beam, increasing detection likelihood.

Radio emissions decay as oscillations damp.

Abstract

We suggest stellar oscillations are responsible for the strange radio behaviors of Anomalous X-ray pulsars and soft Gamma-ray repeaters (AXP/SGRs), within the framework of both solid quark star model and magnetar model. In solid quark star model, the extra voltage provided by oscillations activates the star from under death line to above death line. In magnetar model, oscillations enlarge the radio beam so that increase the possibility to detect it. Later radio emission decays and vanishes as oscillations damp.
