Evidence for mass accretion driven by spiral shocks onto the white dwarf in SDSS J123813.73-033933.0
A. F. Pala, B. T. Gänsicke, T. R. Marsh +21
We present high-time-resolution photometry and phase-resolved spectroscopy of the short-period () cataclysmic variable SDSS J123813.73-033933.…
Third Nearest WZ Sge-Type Dwarf Nova candidate ASASSN-14dx Classified on the Basis of Gaia Data Release 2
Keisuke Isogai, Taichi Kato, Akira Imada +8
ASASSN-14dx showed an extraordinary outburst whose features are the small outburst amplitude (~ 2.3 mag) and long duration (> 4 years). Because we found a long observational gap of…
On the Nature of Long-Period Dwarf Novae with Rare and Low-Amplitude Outbursts
Mariko Kimura, Taichi Kato, Hiroyuki Maehara +35
There are several peculiar long-period dwarf-nova like objects, which show rare, low-amplitude outbursts with highly ionized emission lines. 1SWASP J162117441254, BD Pav, and V3…
ASASSN-16dt and ASASSN-16hg: Promising Candidates for a Period Bouncer
Mariko Kimura, Keisuke Isogai, Taichi Kato +13
We present optical photometry of superoutbursts in 2016 of two WZ Sge-type dwarf novae (DNe), ASASSN-16dt and ASASSN-16hg. Their light curves showed a dip in brightness between the…
Orbital Period Increase in ES Ceti
Enrique de Miguel, Joseph Patterson, Jonathan Kemp +5
We report a long-term study of the eclipse times in the 10-minute helium binary ES Ceti. The binary period increases rapidly, with P/P-dot = 6.2x10^6 yr. This is consistent with th…
