Recent discoveries of weak and fast optical transients raise the question of their origin. We investigate the minimum ejecta mass associated with core-collapse supernovae (SNe) of Type Ic. We show that mass transfer from a helium star to a compact companion can produce an ultra-stripped core which undergoes iron core collapse and leads to an extremely fast and faint SN Ic. In this Letter, a detailed example is presented in which the pre-SN stellar mass is barely above the Chandrasekhar limit…

Ultra-stripped supernovae: progenitors and fate

The explosion of ultra-stripped stars in close binaries can lead to ejecta masses < 0.1 M_sun and may explain some of the recent discoveries of weak and fast optical transients. In Tauris et al.

Multidimensional simulations of ultrastripped supernovae to shock breakout

The recent discoveries of many double neutron star systems and their detection as LIGO-Virgo merger events call for a detailed understanding of their origin. Explosions of ultra-stripped stars in

Light-curve Modeling of Fast-evolving Supernova KSN 2015K: Explosion in Circumstellar Matter of a Super-AGB Progenitor

Recent supernova searches revealed a number of fast-evolving luminous transients. We perform radiation-hydrodynamic simulations of light curves of several models of supernova from super-asymptotic

Radio Emission from Ultra-stripped Supernovae as Diagnostics for Properties of the Remnant Double Neutron Star Binaries

An ultra-stripped supernova (SN) is an explosion of a helium or C+O star whose outer envelope has been stripped away by a companion neutron star. A double neutron star (DNS) binary is believed to be

Abstract We discuss light-curve and spectral properties of ultra-stripped core-collapse supernovae. Ultra-stripped supernovae are supernovae with ejecta masses of only ~0.1M ⊙ whose progenitors lose

The Peculiar Ca-rich SN2019ehk: Evidence for a Type IIb Core-collapse Supernova from a Low-mass Stripped Progenitor

The nature of the peculiar “Ca-rich” SN 2019ehk in the nearby galaxy M100 remains unclear. Its origin has been debated as either a stripped core-collapse supernova or a thermonuclear helium

Final evolution of super-AGB stars and supernovae triggered by electron capture

Abstract Stars of 8–10 M⊙ form a strongly electron-degenerate oxygen–neon–magnesium core which is more massive than ∼1.1 M⊙, and become super-Asymptotic Giant Branch stars. The oxygen–neon–magnesium

A hot and fast ultra-stripped supernova that likely formed a compact neutron star binary

TLDR
The discovery of iPTF 14gqr is interpreted as evidence for ultra-stripped supernovae that form neutron stars in compact binary systems.

Case A and B evolution towards electron capture supernova

Context. Most super-asymptotic giant branch (SAGB) stars are expected to end their life as oxygen–neon white dwarfs rather than electron capture supernovae (ECSN). The reason is ascribed to the

Type Ic Supernovae

In this chapter discusses supernovae of Type Ic (SN Ic), the most stripped of core-collapse supernovae. SN Ic show little evidence for either hydrogen or helium in their ejecta. Nebular spectra have

A faint type of supernova from a white dwarf with a helium-rich companion

TLDR
A faint type Ib supernova is reported in the halo of the nearby isolated galaxy, NGC 1032, and it is concluded that it arises from a low-mass, old progenitor, likely to have been a helium-accreting white dwarf in a binary.

An extremely luminous X-ray outburst at the birth of a supernova

TLDR
This work reports the serendipitous discovery of a supernova at the time of the explosion, marked by an extremely luminous X-ray outburst, and attributes the outburst to the ‘break-out’ of the supernova shock wave from the progenitor star, and shows that the inferred rate of such events agrees with that of all core-collapse supernovae.
