A 12.4-day periodicity in a close binary system after a supernova
Neutron stars and stellar-mass black holes are the remnants of massive star explosions1. Most massive stars reside in close binary systems2, and the interplay between the companion star and the newly formed compa...

Minutes-duration optical flares with supernova luminosities
In recent years, certain luminous extragalactic optical transients have been observed to last only a few days1. Their short observed duration implies a different powering mechanism from the most common luminous e...

Open AccessA radio-detected type Ia supernova with helium-rich circumstellar material
Type Ia supernovae (SNe Ia) are thermonuclear explosions of degenerate white dwarf stars destabilized by mass accretion from a companion star1, but the nature of their progenitors remains poorly understood. A way...

An infrared transient from a star engulfing a planet
Planets with short orbital periods (roughly under 10 days) are common around stars like the Sun1,2. Stars expand as they evolve and thus we expect their close planetary companions to be engulfed, possibly powerin...

A very luminous jet from the disruption of a star by a massive black hole
Tidal disruption events (TDEs) are bursts of electromagnetic energy that are released when supermassive black holes at the centres of galaxies violently disrupt a star that passes too close1. TDEs provide a windo...

Discovery and confirmation of the shortest gamma-ray burst from a collapsar
Gamma-ray bursts (GRBs) are among the brightest and most energetic events in the Universe. The duration and hardness distribution of GRBs has two clusters1, now understood to reflect (at least) two different prog...

Infrared spectropolarimetric detection of intrinsic polarization from a core-collapse supernova
Massive stars die an explosive death as a core-collapse supernova (CCSN). The exact physical processes that cause the collapsing star to rebound into an explosion are not well understood1–3, and the key to resolv...

A tidal disruption event coincident with a high-energy neutrino
Cosmic neutrinos provide a unique window into the otherwise hidden mechanism of particle acceleration in astrophysical objects. The IceCube Collaboration recently reported the likely association of one high-en...

Optical follow-up of the neutron star–black hole mergers S200105ae and S200115j
LIGO and Virgo’s third observing run revealed the first neutron star–black hole (NSBH) merger candidates in gravitational waves. These events are predicted to synthesize r-process elements1,2 creating optical/nea...

Energetic eruptions leading to a peculiar hydrogen-rich explosion of a massive star
Observations of an event (several energetic eruptions leading to a terminal explosion that is surprisingly hydrogen-rich) with the spectrum of a supernova do not match with other observations of supernovae.

Erratum: A strong ultraviolet pulse from a newborn type Ia supernova
Nature 521, 328–331 (2015); doi:10.1038/nature14440 In this Letter, the superscript in the ultraviolet luminosity was listed incorrectly as ‘−41’ rather than ‘41’ in the last sentence of the second paragraph f...

A strong ultraviolet pulse from a newborn type Ia supernova
Observations of declining ultraviolet emission from a type Ia supernova within four days of the explosion are as expected if material ejected by the supernova collided with a companion star, supporting the sin...

Supernova SN 2011fe from an exploding carbon–oxygen white dwarf star
Multi-instrument detection of a nearby type 1a supernova shows that the exploding star was probably a carbon–oxygen white dwarf star in a binary system with a main-sequence companion.

Exclusion of a luminous red giant as a companion star to the progenitor of supernova SN 2011fe
Archival images of the progenitor system of supernova SN 2011fe are so sensitive that the presence of luminous red giants or most helium stars is directly ruled out.
