On the possible nature of Bp-Ap Stars: an application to HD101065 and HR465

TL;DR

This paper proposes that magnetic chemically peculiar stars, such as HD101065 and HR465, may be close binary systems with neutron star companions, explaining their unusual radioactive and magnetic features.

Contribution

It introduces a novel hypothesis that MCP stars are binary systems with neutron stars, providing explanations for their radioactive isotopes and peculiar behaviors.

Findings

Radioactive isotopes detected in some MCP stars explained by neutron star companions

Behavior of MCP stars in radio range accounted for by binary interaction

Phenomena of roAp stars linked to neutron star influence

Abstract

We have proposed the new explanation of some magnetic chemically peculiar (MCP) stars anomalies, which is based on assumption that such stars can be the close binary systems with a secondary component being neutron star. Within this hypothesis one can naturally explain the main anomalous features of MCP stars: first of all, an existence of the short-lived radioactive isotopes detected in some stars (like Przybylski's star and HR465), and some others peculiarities (e.g. the behavior of CU Vir in radio range, the phenomenon of the roAp stars).
