X-ray counterparts to stellar MeerKAT Galactic-plane compact radio sources
O. D. Egbo, P. J. Groot, D. A. H. Buckley +5
Radio emission from magnetically active stars arises mainly from non-thermal processes and complements high-energy X-ray emission. Sensitive, wide-field radio and X-ray surveys now…
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…
TESS and ground-based observations of WZ Sge-type dwarf novae in outburst
Y. Tampo, N. Kojiguchi, K. Isogai +30
Dwarf nova (DN) superoutbursts are accompanied by superhumps, which change their periods and profiles over a superoutburst. We present the TESS and ground-based observations of nin…
A MeerKAT survey of nearby dwarf novae: I. New detections
J. Kersten, E. Körding, P. A. Woudt +8
A program to search for radio emission from dwarf-novae-type cataclysmic variables was conducted with the South African MeerKAT radio telescope. The dwarf novae RU Pegasi, V426 Oph…
