Cataclysmic variables from SRG/eROSITA: new systems from eRASS1
A. D. Schwope, J. Brink, D. A. H. Buckley +12
(abridged) Aims. We aim to generate large samples of CVs selected from the SRG/eROSITA surveys to address fundamental questions about binary evolution, the role of magnetic fields…
The optical photometric and spectroscopic periodicities of the cataclysmic variable SRGt 062340.2-265751
J. Brink, D. A. H. Buckley, M. Veresvarska +10
We report on optical spectroscopic and photometric follow-up observations of the eROSITA discovered transient SRGt 062340.2-265751 and show that it displays the characteristics of…
Disc Winds From Accreting Systems in the 2040s
Noel Castro Segura, Virginia Cúneo, Francesco Tombesi +9
What does the temporal evolution of disc winds tell us about accreting systems and the accretion process? Studies of accretion-disc outflows across all mass scales, including accre…
Confirmation of SRGt 062340.2-265751 as a nova-like cataclysmic variable with a possible magnetic nature
V. A. Cúneo, A. D. Schwope, J. Kurpas +5
SRGt 062340.2-265751, a cataclysmic variable identified by SRG/eROSITA thanks to its significant X-ray variability, remains poorly characterised despite the multi-wavelength follow…
State-dependent signatures of jets and winds in the optical and infrared spectrum of the black hole transient GX 3394
A. Ambrifi, D. Mata Sánchez, T. Muñoz-Darias +14
GX 3394 is one of the prototypical black hole X-ray transients, exhibiting recurrent outbursts that allow detailed studies of black hole accretion and ejection phenomena. In thi…
Unveiling optical signatures of outflows in accreting white dwarfs
V. A. Cúneo, T. Muñoz-Darias, F. Jiménez-Ibarra +8
Accreting white dwarfs are known to show signatures of wind-type outflows in the ultraviolet. At optical wavelengths, however, wind detections have only been reported for a few sou…
UltraCompCAT: a comprehensive Catalogue of Ultra-Compact and Short Orbital Period X-ray Binaries
M. Armas Padilla, J. M. Corral-Santana, A. Borghese +4
Ultracompact X-ray binaries (UCXBs) are a distinctive but elusive family of low-mass X-ray binaries (LMXBs) characterised by their tight orbits and degenerate donor stars. Here we…
Optical and near-infrared spectroscopy of the black hole transient 4U 1543-47 during its 2021 ultra-luminous state
J. Sánchez-Sierras, T. Muñoz-Darias, J. Casares +10
We present simultaneous optical and near-infrared spectra obtained during the 2021 outburst of the black hole transient 4U 1543-47. The X-ray hardness-intensity diagram and the com…
Discovery of optical and infrared accretion disc wind signatures in the black hole candidate MAXI J1348-630
G. Panizo-Espinar, M. Armas Padilla, T. Muñoz-Darias +11
MAXI J1348-630 is a low mass X-ray binary discovered in 2019 during a bright outburst. During this event, the system sampled both hard and soft states following the standard evolut…
Failed-Transition outbursts in Black hole low-mass X-ray binaries
K. Alabarta, D. Altamirano, M. Méndez +6
Black hole low-mass X-ray binaries (BH LMXBs) evolve in a similar way during outburst. Based on the X-ray spectrum and variability, this evolution can be divided into three canonic…
X-ray Spectral and Timing evolution of MAXI J1727-203 with NICER
K. Alabarta, D. Altamirano, M. Méndez +16
We present a detailed X-ray spectral and variability study of the full 2018 outburst of MAXI J1727-203 using NICER observations. The outburst lasted approximately four months. Spec…
An illumination effect and an eccentric orbit for the symbiotic binary PU Vul revealed by 32 years of optical spectroscopy
Virginia A. Cúneo, Scott J. Kenyon, Mercedes N. Gómez +3
We analyze 32 years of optical spectra and photometry for the symbiotic binary PU Vul. Light curves for the He I 4471, He II 4686 and H 4861 emission lines reveal…
