How Mass Flows Through Accretion Discs: A Spectral-Timing Vision for the 2040s

Simone Scaringi, Domitilla de Martino, Anna F. Pala +17

Understanding how mass and angular momentum flow through accretion discs remains a fundamental unsolved problem in astrophysics. Accreting white dwarfs offer an ideal laboratory fo…

WZ Sge-type dwarf novae: an extreme laboratory in cataclysmic variables

Yusuke Tampo

WZ Sge-type dwarf novae form one of the most intriguing classes of compact accreting binaries. They are recognized as the most evolved population of hydrogen-rich cataclysmic varia…

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…

Discovering Cataclysmic Variables from the Rubin Observatory LSST

D. A. H. Buckley, Y. Tampo, P. Szkody +8

The Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) will provide a windfall of new transients and variable sources. Here we have performed mock observation simul…

TCP J072226836220548: a new AM CVn type system with infrequent outbursts

Alexander Tarasenkov, Kirill Sokolovsky, Alexandr Dodin +11

We present the discovery of TCP J072226836220548, a new ultracompact binary system of the AM CVn type. This system was first identified displaying a mag outburst on 2…

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…

Spectral evolution of the narrow emission line components in optical during the 2022 nova eruption of U Scorpii

Katsuki Muraoka, Naoto Kojiguchi, Junpei Ito +20

There remains debate over whether the accretion disk survives or is entirely disrupted after the nova eruption. In our previous paper, Muraoka et al. (2024, PASJ, 76, 293) have pho…
