The mergers of binary compact objects such as neutron stars and black holes are of central
interest to several areas of astrophysics, including as the progenitors of gamma-ray bursts …

Planetary rings are observed not only around giant planets, but also around small bodies
such as the Centaur Chariklo and the dwarf planet Haumea. Up to now, all known dense …

Quasi-periodic eruptions (QPEs) are luminous bursts of soft X-rays from the nuclei of
galaxies, repeating on timescales of hours to weeks,,,–. The mechanism behind these rare …

White dwarf stars are the most common stellar fossils. When in binaries, they make up the
dominant form of compact object binary within the Galaxy and can offer insight into different …

Long gamma-ray bursts (GRBs) are believed to originate from core collapse of massive
stars. High-redshift GRBs can probe the star formation and reionization history of the early …

Abstract Fast X-ray Transients (FXTs) are X-ray flares with durations ranging from a few
hundred seconds to a few hours. Possible origins include the tidal disruption of a white …

White dwarfs, the extremely dense remnants left behind by most stars after their death, are
characterized by a mass comparable to that of the Sun compressed into the size of an Earth …

White dwarf stars are ubiquitous in the Galaxy, and are essential to understanding stellar
evolution. While most white dwarfs are photometrically stable and reliable flux standards …

This paper investigates the frequency of transiting planetary systems around metal-polluted
white dwarfs using high-cadence photometry from ULTRACAM and ULTRASPEC on the …

Black widows are extreme millisecond pulsar binaries where the pulsar wind ablates their
low-mass companion stars. In the optical range, their light curves vary periodically due to the …
