Size, shape, density, and atmospheric limit of (50000) Quaoar revealed from 14 years of stellar occultation
Giuliano Margoti, Felipe Braga-Ribas, José Luis Ortiz +173
We present results from 28 stellar occultations by the large Trans-Neptunian Object (50000) Quaoar registered between 2018 and 2025. By performing a joint analysis of this occultat…
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…
Analysis of optical spectroscopy and photometry of the type I X-ray bursting system UW CrB
M. R. Kennedy, P. Callanan, P. M. Garnavich +19
UW Coronae Borealis (UW CrB) is a low mass X-ray binary that shows both Type 1 X-ray and optical bursts, which typically last for 20 s. The system has a binary period of close to 2…
GOTO065054+593624: a 8.5 mag amplitude dwarf nova identified in real time via Kilonova Seekers
T. L. Killestein, G. Ramsay, M. Kennedy +62
Dwarf novae are astrophysical laboratories for probing the nature of accretion, binary mass transfer, and binary evolution -- yet their diverse observational characteristics contin…
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-…
