Open AccessJWST detection of a supernova associated with GRB 221009A without an r-process signature
Identifying the sites of r-process nucleosynthesis, a primary mechanism of heavy element production, is a key goal of astrophysics. The discovery of the brightest gamma-ray burst (GRB) to date, GRB 221009A, pr...

Radiative Emission Mechanisms
We describe how the various outcomes of stellar tidal disruption give rise to observable radiation. We separately consider the cases where gas circularizes rapidly into an accretion disc, as well as the case w...

Open AccessObservable signatures of dark photons from supernovae
A dark photon is a well-motivated new particle which, as a component of an associated dark sector, could explain dark matter. One strong limit on dark photons arises from excessive cooling of supernovae. We po...

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.

Optical emission from a kilonova following a gravitational-wave-detected neutron-star merger
Optical to near-infrared observations of a transient coincident with the detection of the gravitational-wave signature of a binary neutron-star merger and a low-luminosity short-duration γ-ray burst are presen...

Origin of the heavy elements in binary neutron-star mergers from a gravitational-wave event
Modelling the electromagnetic emission of kilonovae enables the mass, velocity and composition (with some heavy elements) of the ejecta from a neutron-star merger to be derived from the observations.

Unusual Supernovae and Alternative Power Sources
Recent observations have revealed a diverse class of peculiar supernovae, among them transients that are extremely luminous and unusually dim, or that evolve remarkably rapidly or slowly over time. The light c...

Erratum: No signature of ejecta interaction with a stellar companion in three type Ia supernovae
Nature 521, 332–335 (2015); doi:10.1038/nature14455 Owing to a typesetter error, the final word ‘days’ was missing from the end of the Table 1 footnote in the PDF and print versions (the HTML is correct). The ...

No signature of ejecta interaction with a stellar companion in three type Ia supernovae
The explosion of a type Ia supernova could be triggered either by accretion from a companion—which should be indicated by brightening caused by interaction of supernova ejecta with the companion—or by a merger...

Super-luminous supernovae on the rise
New observations suggest that certain extremely bright supernovae are not the nuclear explosions of very massive stars. Instead, they may be ordinary-mass events lit up by a potent central fountain of magnetic...

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.

The supernova has two faces
The variety of stellar deaths is less than we thought. A compilation of new and archival data shows that two previously distinct subtypes of supernova are actually two sides of the same lopsided coin.

Rapid heating of the atmosphere of an extrasolar planet
Many 'hot Jupiter' extrasolar planets are known. Their properties vary, but virtually all are thought to be spin-synchronized, so that the same hemisphere faces the parent star at all times. HD 80606b breaks t...
