In this paper we show that the most luminous supernova discovered very recently, ASASSN-15lh, could have been powered by a newborn ultra-strongly-magnetized pulsar, which initially rotates near the Kepler limit. We find that if this pulsar is a neutron star, its rotational energy could be quickly lost as a result of gravitational-radiation-driven r-mode instability; if it is a strange quark star, however, this instability is highly suppressed due to a large bulk viscosity associated with the… Expand

Extreme Supernova Models for the Super-luminous Transient ASASSN-15lh
The recent discovery of the unprecedentedly super-luminous transient ASASSN-15lh (or SN 2015L) with its UV-bright secondary peak challenges all the power-input models that have been proposed forExpand
Magnetar-Powered Supernovae in Two Dimensions. I. Superluminous Supernovae
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 alsoExpand
Internal x-ray plateau in short GRBs: Signature of supramassive fast-rotating quark stars?
A supramassive, strongly-magnetized millisecond neutron star (NS) has been proposed to be the candidate central engine of at least some short gamma-ray bursts (SGRBs), based on the "internal plateau"Expand
Gravitational waves within the magnetar model of superluminous supernovae and gamma-ray bursts
The light curve of many supernovae (SNe) and gamma-ray bursts (GRBs) can be explained by a sustained injection of extra energy from its possible central engine, a rapidly rotating strongly magneticExpand
Studying newborn neutron stars by the transient emission after stellar collapses and compact binary mergers.
The formation of neutron stars (NSs), both from collapses of massive stars and mergers of compact objects, can be usually indicated by bright transients emitted from explosively-ejected material. InExpand
Evolution of newborn rapidly rotating magnetars: effects of r-mode and fall-back accretion
In this paper we investigate effects of the $r$-mode instability on a newborn rapidly-rotating magnetar with fall-back accretion. Such a magnetar could usually occur in core-collapse supernovae andExpand
On the Energy Sources of the Most Luminous Supernova ASASSN-15lh
In this paper, we investigate the energy-source models for the most luminous supernova ASASSN-15lh. We revisit the ejecta-circumstellar medium (CSM) interaction (CSI) model and the CSI plus magnetarExpand
Jets launched at magnetar birth cannot be ignored
Abstract I question models for powering super energetic supernovae (SESNe) with a magnetar central engine that do not include jets that are expected to be launched by the magnetar progenitor. I showExpand
Explaining the most energetic supernovae with an inefficient jet-feedback mechanism
We suggest that the energetic radiation from core-collapse super-energetic supernovae (SESNe) is due to a long lasting accretion process onto the newly born neutron star (NS), resulting from anExpand
Estimation of 56Ni Needed in the Explosion Process of the Super Luminous Supernova ASASSN-15lh
Abstract ASASSN-15lh is a super luminous supernova, whose light curve is similar to that of the type Ia supernova (SN Ia). Since the luminosity of SN Ia is directly related to the decay of 56Ni, inExpand


Bright Supernovae from Magnetar Birth
Following an initial explosion that might be launched either by magnetic interactions or neutrinos, a rotating magnetar radiating according to the classic dipole formula could power a very luminousExpand

The hypothesis, that pulsars can produce supernova explosions of type II, is explored with the aid of detailed hydrodynamical calculations. Preliminary calculations performed with Gunn (1971)Expand

Relativistic wind bubbles and afterglow signatures
Highly magnetized, rapidly rotating compact objects are widely argued to be central energy sources of γ-ray bursts (GRBs). After the GRB, such a magnetar-like object may directly lose its rotationalExpand
ASASSN-15lh: A highly super-luminous supernova
The most luminous supernova yet found was glimpsed in an unusual host galaxy, and has several major features characteristic of the hydrogen-poor super-luminous supernovae (SLSNe-I), whose energy sources and progenitors are currently poorly understood. Expand
Magnetar Driven Shock Breakout and Double Peaked Supernova Light Curves

A two-solar-mass neutron star measured using Shapiro delay
Radio timing observations of the binary millisecond pulsar J1614-2230 that show a strong Shapiro delay signature are presented and the pulsar mass is calculated to be (1.97 ± 0.04)M⊙, which rules out almost all currently proposed hyperon or boson condensate equations of state. Expand
