ZTF J021804.16+071152.93: a dead cataclysmic variable and potential solution to the missing period bouncers

S. G. Parsons, A. J. Brown, S. L. Casewell +22

It is predicted that half or more of all cataclysmic variables (CVs) should have evolved past the period minimum and now exist as so-called "period bouncers" where a white dwarf sh…

No Period Change in Two Long-Period AM CVn Binaries

Matthew J. Green, Thomas R. Marsh, Jan van Roestel +25

Ultracompact binary systems, consisting of two compact objects in an orbit , should exhibit measurable rates of orbital period change () due t…

Photometric masses for long period CVs: the case study of CSS131106

M. Das, S. P. Littlefair, S. G. Parsons +15

We present high-speed photometry of the eclipsing cataclysmic variable CSS131106 J052412+004148. We determine the system parameters by modelling the eclipse lightcurve using the ph…

Searching for outbursts from Symbiotic Binaries in GOTO and ATLAS data

G. Ramsay, K. Ackley, S. Belkin +46

Symbiotic Binaries contain a white dwarf accreting material from a red giant star typically through a wind. We present the results of a search for outbursts from Symbiotic Binaries…

The Gravitational-wave Optical Transient Observer (GOTO) data pipeline and workflow for transient discovery

J. D. Lyman, D. O'Neill, T. Killestein +45

Wide-field and high-cadence sky surveys are the first step in the chain of discovery and characterisation of astrophysical transients such as supernovae, kilonovae, and tidal disru…

Long-term eclipse time variations in white dwarf binaries

Amalie Yates, S. G. Parsons, A. J. Brown +15

The overwhelming majority of eclipsing white dwarf (WD) binary systems show quasi-periodic variations in eclipse timings on many year timescales. Currently, the mechanism behind th…

GOTO identification and broadband modelling of the counterpart to the SVOM GRB 250818B

S. Belkin, G. P. Lamb, K. Ackley +61

Rapid localisation and follow-up of gamma-ray bursts (GRBs) increasingly rely on low-latency triggers from new missions coupled to wide-field robotic optical facilities. We present…

An eclipsing 8.56 minute orbital period mass-transferring binary

Emma T. Chickles, Joheen Chakraborty, Kevin B. Burdge +34

We report the discovery of ATLAS J101342.5-451656.8 (hereafter ATLAS J1013-4516), an 8.56 minute orbital period mass transferring AM Canum Venaticorum binary with mean Gaia magnitu…

Giant outbursts of clumpy material preceding Type II supernova 2024qiw

T. Nagao, H. Kuncarayakti, K. Maeda +6

Observations of core-collapse supernovae suggest that some massive stars undergo intense mass loss shortly before explosion, but the underlying mechanisms remain unknown. Here we r…

SN 2024cld: unveiling the complex mass-loss histories of evolved supergiant progenitors to core collapse supernovae

T. L. Killestein, M. Pursiainen, R. Kotak +52

Pre-explosion mass loss in supernova (SN) progenitors is a crucial unknown factor in stellar evolution, yet has been illuminated recently by the diverse zoo of interacting transien…

Constraints on an optical counterpart for the long-period radio transient GPM J1839-10

Ingrid Pelisoli, A. J. Brown, N. Castro Segura +14

Long period radio transients (LPTs) are periodic radio sources showing pulsed emission on timescales from minutes to hours. The underlying sources behind this emission are currentl…

A Sibling of AR Scorpii: SDSS J230641.47244055.8 and the Observational Blueprint of White Dwarf Pulsars

N. Castro Segura, I. Pelisoli, B. T. Gänsicke +21

Radio pulsating white dwarf (WD) systems, known as WD pulsars, are non-accreting binary systems where the rapidly spinning WD interacts with a low-mass companion producing pulsed n…

SN 2024bfu, SN 2025qe, and the early light curves of type Iax supernovae

M. R. Magee, T. L. Killestein, M. Pursiainen +39

Type Iax supernovae (SNe Iax) are one of the most common subclasses of thermonuclear supernova and yet their sample size, particularly those observed shortly after explosion, remai…

A targeted search for binary white dwarf pulsars using Gaia and WISE

Ingrid Pelisoli, T. R. Marsh, G. Tovmassian +24

After its discovery in 2016, the white dwarf binary AR Scorpii (AR Sco) remained for several years the only white dwarf system to show pulsed radio emission associated with a fast-…

Two almost planetary mass survivors of common envelope evolution

S. G. Parsons, A. J. Brown, S. L. Casewell +19

White dwarfs are often found in close binaries with stellar or even substellar companions. It is generally thought that these compact binaries form via common envelope evolution, t…

Expanding the ultracompacts: gravitational wave-driven mass transfer in the shortest-period binaries with accretion disks

Joheen Chakraborty, Kevin B. Burdge, Saul A. Rappaport +35

We report the discovery of three ultracompact binary white dwarf systems hosting accretion disks, with orbital periods of 7.95, 8.68, and 13.15 minutes. This significantly augments…
