Aims. Pair creation supernovae (PCSN) are thought to be produced from very massive low metallicity stars. The spectacularly bright SN 2006gy does show several signatures expected from PCSNe. Here, we investigate the metallicity threshold below which PCSN can form and estimate their occurrence rate. Methods. We perform stellar evolution calculations for stars of 150 Mand 250 Mof low metallicity (Z� / 5a ndZ� /20), and analyze their mass loss rates. Results. We find that the bifurcation between… Expand

Observational properties of low-redshift pair instability supernovae
Context. So called superluminous supernovae have been recently discovered in the local Universe. It appears possible that some of them originate from stellar explosions induced by the pairExpand
Pair-instability Supernovae in the Local Universe
The discovery of 150-300 M {sub ☉} stars in the Local Group and pair-instability supernova candidates at low redshifts has excited interest in this exotic explosion mechanism. Realistic light curvesExpand
Core-collapse supernovae in low-metallicity environments and future all-sky transient surveys
Aims. Massive stars in low-metallicity environments may produce exotic explosions such as long-duration gamma-ray bursts and pair-instability supernovae when they die as core-collapse supernovaeExpand
Explosion and nucleosynthesis of low redshift pair instability supernovae
Both recent observations and stellar evolution models suggest that pair-instability supernovae (PISNe) could occur in the local Universe, at metallicities below Z_Sun/3. Previous PISN models wereExpand
Nebular spectra of pair-instability supernovae
If very massive stars (M >~ 100 Msun) can form and avoid too strong mass loss during their evolution, they are predicted to explode as pair-instability supernovae (PISNe). One critical test forExpand
Emission from Pair-Instability Supernovae with Rotation
Pair-instability supernovae (PISNe) have been suggested as candidates for some superluminous supernovae, such as SN 2007bi, and as one of the dominant types of explosion occurring in the earlyExpand
OGLE14-073 – a promising pair-instability supernova candidate
The recently discovered bright type II supernova OGLE14-073 evolved very slowly. The light curve rose to maximum for 90 days from discovery and then declined at a rate compatible with the radioactiveExpand
Pair-instability supernovae via collision runaway in young dense star clusters
Stars with helium cores between ∼64 and 133 M⊙ are theoretically predicted to die as pair-instability supernovae. This requires very massive progenitors, which are theoretically prohibited for PopExpand
Can pair-instability supernova models match the observations of superluminous supernovae?
An increasing number of so-called superluminous supernovae (SLSNe) are discovered. It is believed that at least some of them with slowly fading light curves originate in stellar explosions induced byExpand
Superluminous supernova progenitors have a half-solar metallicity threshold
Host galaxy properties provide strong constraints on the stellar progenitors of superluminous supernovae. By comparing a sample of 19 low-redshift (z < 0.3) superluminous supernova hosts to galaxyExpand

The Detectability of Pair-Production Supernovae at z 6
Nonrotating, zero-metallicity stars with initial masses 140 M 260 M☉ are expected to end their lives as pair-production supernovae (PPSNe), in which an electron-positron pair-production instabilityExpand

A giant outburst two years before the core-collapse of a massive star
TLDR
It is reported that the peculiar type Ib supernova SN 2006jc is spatially coincident with a bright optical transient that occurred in 2004, andSpectroscopic and photometric monitoring of the supernova leads us to suggest that the progenitor was a carbon-oxygen Wolf–Rayet star embedded within a helium-rich circumstellar medium.

Evolution of rapidly rotating metal-poor massive stars towards gamma-ray bursts
Recent models of rotating massive stars including magnetic fields prove it difficult for the cores of single stars to retain enough angular momentum to produce a collapsar and gamma-ray burst. At lowExpand
