The Long-Period Radio Transient and Cataclysmic Variable ASKAP J1745-5051: Evidence for a 15,000 K White Dwarf and a Sub-Stellar Donor

Christian Knigge, Simone Scaringi, Noel Castro Segura +2

Long-period transients (LPTs) are radio sources that exhibit polarized periodic radio bursts on time-scales of minutes to hours. At least some LPTs are associated with white dwarfs…

The X-ray emission of the long-period transient and accreting cataclysmic variable ASKAP J174508.9-505149

M. Imbrogno, M. Veresvarska, Y. L. Wang +8

Long-period transients (LPTs) challenge our knowledge of the mechanism producing radio periodic pulsations in compact objects. Some LPTs have been associated with systems hosting a…

A Catalogue of Orbital Periods of Cataclysmic Variables and Candidates from TESS Observations

Meryem K. Dağ, Simone Scaringi, Kieran O'Brien +21

We present a systematic analysis of 2544 cataclysmic variable systems and related candidates observed by the Transiting Exoplanet Survey Satellite (TESS), with the aim of compiling…

The supernova Ia progenitor problem in the 2040s

Thomas Kupfer, Simone Scaringi, Ingrid Pelisoli +8

Type Ia supernovae (SNe Ia) are fundamental to cosmology and galactic chemical evolution, yet the nature of their progenitor systems remains unresolved. Multiple evolutionary pathw…

The final stages of binary evolution using multi-messenger studies

Thomas Kupfer, Simone Scaringi, Paul Groot +11

Ultracompact Galactic binaries with orbital periods below an hour are among the strongest persistent gravitational-wave (GW) sources in the mHz band and will constitute the dominan…

White Dwarf Binaries: Probes of Future Astrophysics

Anna F. Pala, Roberto Raddi, Alberto Rebassa-Mansergas +25

White dwarf binaries are fundamental astrophysical probes. They represent ideal laboratories to test the models of binary evolution, which also apply to the sources of gravitationa…
