Survey of Period Variations of Superhumps in SU UMa-Type Dwarf Novae. X: The Tenth Year (2017)
Taichi Kato, Keisuke Isogai, Yasuyuki Wakamatsu +67
Continuing the project described by Kato et al. (2009, PASJ, 61, S395, arXiv/0905.1757), we collected times of superhump maxima for 102 SU UMa-type dwarf novae observed mainly duri…
NSV 1440: First WZ Sge-type Object in AM CVn stars and candidates
Keisuke Isogai, Taichi Kato, Berto Monard +5
In 2015 and 2017, the AM CVn candidate NSV 1440 showed superoutbursts having the characteristic features of WZ Sge-type dwarf novae (DNe). By analogy with hydrogen-rich cataclysmic…
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…
A 16-Year Photometric Campaign on the Eclipsing Novalike Variable DW Ursae Majoris
D. R. S. Boyd, E. de Miguel, J. Patterson +29
We present an analysis of photometric observations of the eclipsing novalike variable DW UMa made by the CBA consortium between 1999 and 2015. Analysis of 372 new and 260 previousl…
Repetitive Patterns in Rapid Optical Variations in the Nearby Black-hole Binary V404 Cygni
Mariko Kimura, Keisuke Isogai, Taichi Kato +65
How black holes accrete surrounding matter is a fundamental, yet unsolved question in astrophysics. It is generally believed that matter is absorbed into black holes via accretion…
Breaking the spatial resolution barrier via iterative sound-light interaction in deep tissue microscopy
Ke Si, Reto Fiolka, Meng Cui
Optical microscopy has so far been restricted to superficial layers, leaving many important biological questions unanswered. Random scattering causes the ballistic focus, which is…
