We show that energy deposited into an expanding supernova remnant by a highly magnetic (B ~ 5 × 1014 G) neutron star spinning at an initial period of Pi ≈ 2-20 ms can substantially brighten the light curve. For magnetars with parameters in this range, the rotational energy is released on a timescale of days to weeks, which is comparable to the effective diffusion time through the supernova remnant. The late time energy injection can then be radiated without suffering overwhelming adiabatic…

Magnetar Driven Shock Breakout and Double Peaked Supernova Light Curves
• Physics
• 2015
The light curves of some luminous supernovae are suspected to be powered by the spindown energy of a rapidly rotating magnetar. Here we describe a possible signature of the central engine: a burst of
Signatures of pulsars in the light curves of newly formed supernova remnants
• Physics
• 2013
We explore the effect of pulsars, in particular those born with millisecond periods, on their surrounding supernova ejectas. While they spin down, fast-spinning pulsars release their tremendous

Rapidly rotating, strongly magnetized neutron stars (magnetars) can release their enormous rotational energy via magnetic spin-down, providing a power source for bright transients such as
Magnetar-Powered Supernovae in Two Dimensions. I. Superluminous Supernovae
• Physics
• 2016
Previous studies have shown that the radiation emitted by a rapidly rotating magnetar embedded in a young supernova can greatly amplify its luminosity. These one-dimensional studies have also
Simulations of light curves and spectra for superluminous Type Ic supernovae powered by magnetars
Numerous superluminous supernovae (SLSNe) of Type Ic have been discovered and monitored in the last decade. The favored mechanism at their origin is a sustained power injection from a magnetar. This
Optical Transients Powered by Magnetars: Dynamics, Light Curves, and Transition to the Nebular Phase
Millisecond magnetars can be formed via several channels: core-collapse of massive stars, accretion-induced collapse of white dwarfs (WDs), double WD mergers, double neutron star (NS) mergers, and
Magnetar-Powered Supernovae in Two Dimensions. II. Broad-Line Supernovae Ic
Nascent neutron stars with millisecond periods and magnetic fields in excess of $10^{16}$ Gauss can drive highly energetic and asymmetric explosions known as magnetar-powered supernovae. These exotic

Some fraction of the material ejected in a core collapse supernova explosion may remain bound to the compact remnant, and eventually turn around and fall back. We show that the late time
Rapidly Rising Optical Transients from the Birth of Binary Neutron Stars
• Physics
• 2017
We study optical counterparts of a new-born pulsar in a double neutron star system like PSR J0737-3039A/B. This system is believed to eject a small amount of mass of $\mathcal{O}(0.1M_{\odot})$ at
A fast-evolving luminous transient discovered by K2/Kepler
For decades, optical time-domain searches have been tuned to find ordinary supernovae, which rise and fall in brightness over a period of weeks. Recently, supernova searches have improved their

Supernova remnant energetics and magnetars: no evidence in favour of millisecond proto-neutron stars
It is generally accepted that anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs) are magnetars, i.e. neutron stars with extremely high surface magnetic fields (B > 1014 G). The origin

The Kelvin-Helmholtz cooling epoch, lasting tens of seconds after the birth of a neutron star in a successful core-collapse supernova, is accompanied by a neutrino-driven wind. For magnetar-strength

We outline the possible physical processes, associated timescales, and energetics that could lead to the production of pulsars, jets, asymmetric supernovae, and weak ?-ray bursts in routine
Magnetar-Driven Magnetic Tower as a Model for Gamma-Ray Bursts and Asymmetric Supernovae

We consider a newly born millisecond magnetar, focusing on its interaction with the dense stellar plasma in which it is initially embedded. We argue that the confining pressure and inertia of the

For pulsars similar to the one in the Crab Nebula, most of the energy input to the surrounding wind nebula occurs on a timescale 103 yr; during this time, the nebula expands into freely expanding
Magnetized relativistic jets and long-duration GRBs from magnetar spin-down during core-collapse supernovae
We use ideal axisymmetric relativistic magnetohydrodynamic simulations to calculate the spin-down of a newly formed millisecond, B ∼ 10 15 G, magnetar and its interaction with the surrounding stellar

In this paper we investigate the dynamical effect of a pulsar on a surrounding supernova (SN) envelope and the process of thermalization of the pulsar strong waves, with the view of applying the
Supernova 2007bi as a pair-instability explosion
Observations of supernova SN 2007bi are reported, a luminous, slowly evolving object located within a dwarf galaxy, and it is shown that >3 of radioactive 56Ni was synthesized during the explosion and that the observations are well fitted by models of pair-instability supernovae.
