# Magnetar Powered Ordinary Type IIP Supernovae

## TL;DR

This paper explores how magnetar spin-down energy can power ordinary Type IIP supernovae, suggesting rotation and magnetic fields influence their light curves, expanding understanding beyond super-luminous cases.

## Contribution

It demonstrates that magnetar energy can produce both normal and peculiar Type IIP supernova light curves, a novel insight into supernova diversity.

## Key findings

- Magnetar spin-down can power typical Type IIP supernova light curves.
- Proposed mechanism can explain both normal and peculiar light curves.
- Rotation and magnetic fields may influence supernova explosion properties.

## Abstract

We investigate the properties of Type IIP supernovae that are dominantly powered by the rotational kinetic energy of the newly born neutron star. While the spin-down of a magnetar has previously been proposed as a viable energy source in the context of super-luminous supernovae, we show that a similar mechanism could produce both normal and peculiar Type IIP supernova light curves from red supergiant progenitors for a range of initial spin periods and equivalent dipole magnetic field strengths. Although the formation channel for such magnetars in a typical red supergiant progenitor is unknown, it is tantalizing that this proof of concept model is capable of producing ordinary Type IIP lightcurve properties, perhaps implying that rotation rate and magnetic field strength may play important roles in some ordinary looking Type IIP supernova explosions.
