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…

ASASSN-24hd; a dwarf nova bridging WZ Sge-type and SU UMa-type superoutbursts
Yusuke Tampo, Naoto Kojiguchi, Taichi Kato +9
WZ Sge-type dwarf novae (DNe) form a subclass in cataclysmic variables, characterized by short-period variations called superhumps during an outburst. Here we present optical groun…
