Followup ground-based observations of the dwarf nova KZ Gem
Zhibin Dai, Paula Szkody, John R. Thorstensen +1
We present spectroscopy of stars in the immediate vicinity of the dwarf nova (DN) KZ Gem to confirm its identification, which had been ambiguous in the literature. Analysis of 73 r…
A Comprehensive K2 and Ground-Based Study of CRTS J035905.9+175034, an Eclipsing SU UMa System with a Large Mass Ratio
Colin Littlefield, Peter Garnavich, Mark Kennedy +2
CRTS J035905.9+175034 is the first eclipsing SU UMa system for which a superoutburst has been observed by Kepler in the short-cadence mode. The light curve contains one superoutbur…
Followup Observations of SDSS and CRTS Candidate Cataclysmic Variables II
Paula Szkody, Mark E. Everett, Zhibin Dai +1
Spectra of 38 candidate or known cataclysmic variables are presented. Most are candidate dwarf novae or systems containing possible highly magnetic white dwarfs, while a few (KR Au…
Quiescent photometric modulations of two low-inclination cataclysmic variables KZGem and TWVir
Zhibin Dai, Paula Szkody, Ali Taani +2
The quiescent periodic photometric modulations of two low-inclination cataclysmic variables observed in Kepler K2 Campaigns 0 and 1, KZ Gem and TW Vir, are investigated. A phase-co…
Hubble Space Telescope Ultraviolet Light Curves Reveal Interesting Properties of CC Sculptoris and RZ Leonis
Paula Szkody, Anjum S. Mukadam, Odette Toloza +6
Time-tag ultraviolet data obtained on the Hubble Space Telescope in 2013 reveal interesting variability related to the white dwarf spin in the two cataclysmic variables RZ Leo and…
Cataclysmic Variables observed during K2 Campaigns 0 and 1
Zhibin Dai, Paula Szkody, Peter M. Garnavich +1
There are 15 cataclysmic variables (CVs) observed in the first two campaigns of the K2 mission. In this paper, the eight CVs showing distinct features are analyzed in detail. Among…
Updated photometry and orbital period analysis for the polar \objectname{am herculis} on the upper edge of the period gap
Zhibin Dai, Shengbang Qian, Linjia Li
Twenty-one new optical light curves, including five curves obtained in 2009 and sixteen curves detected from the AAVSO International Database spanning from 1977 to 2011, demonstrat…
Orbital period analysis of eclipsing Z Cam-type Dwarf Nova EM Cygni: Evidence of magnetic braking and a third body
Zhibin Dai, Shengbang Qian
Combining with our newest CCD times of light minimum of EM Cygni, all 45 available times of light minimum including 7 data with large scatters are compiled and the updated O-C anal…
A cyclical period variation detected in the updated orbital period analysis of TV Columbae
Zhibin Dai, Shengbang Qian, Eduardo Fernández Lajús +1
The two CCD photometries of the intermediate polar TV Columbae are made for obtaining the two updated eclipse timings with high precision. There is an interval time \sim 17yr since…
