Negative superhumps in the eclipsing Z Cam + VY Scl star ES Dra

  title={Negative superhumps in the eclipsing Z Cam + VY Scl star ES Dra},
  author={Taichi Kato},
I analyzed All-Sky Automated Survey for Supernovae (ASAS-SN) Sky Patrol data of ES Dra and clas-sified it to be a Z Cam star with VY Scl-type fading episodes. An analysis of Transiting Exoplanet Survey Satellite (TESS) observations showed that this object shows shallow eclipses and that the orbital period is 0.17749895(17) d. Negative superhumps with a period of 0.167830(2) d and the beat phenomenon between the period of negative superhumps and the orbital period were detected in the TESS data…

KIC 9406652, one of the recently identified IW And-type dwarf novae, is the best target for studying the tilted disk in cataclysmic variable stars. In a previous paper by Kimura et al. (2020b,

A Step towards Unveiling the Nature of Three Cataclysmic Variables: LS Cam, V902 Mon, and SWIFT J0746.3-1608

We have carried out detailed time-resolved timing analyses of three cataclysmic variables (CVs) namely LS Cam, V902 Mon, and SWIFT J0746.3-1608, using the long-baseline, high-cadence optical

The Physical Origin of Negative Superhumps in Cataclysmic Variables

It has been suspected for over 20 years that the observed negative superhumps in cataclysmic variables are due to the retrograde precession of a tilted disk. We present new smooth particle

The orbital period and variability of the dwarf nova ES Draconis

SPH simulations of negative (nodal) superhumps: a parametric study

Negative superhumps in cataclysmic variable systems result when the accretion disc is tilted with respect to the orbital plane. The line of nodes of the tilted disc precesses slowly in the retrograde

Survey of Period Variations of Superhumps in SU UMa-Type Dwarf Novae

Continuing the project described by Kato et al. (2009, PASJ, 61, S395), we collected times of superhump maxima for 102 SU UMa-type dwarf novae observed mainly during the 2017 season, and

The Donor Stars of Cataclysmic Variables

We construct a complete, semi-empirical donor sequence for CVs with orbital periods less than 6 hrs. All key physical and photometric parameters of CV secondaries (along with their spectral types)

The Z CamPaign: Year 1

The Cataclysmic Variable Section of the American Association of Variable Star Observers (AAVSO) has initiated an observing campaign to study a subset of dwarf novae (DNe), known as Z Cam type (UGZ).

Analysis of the AAVSO light curves of 21 dwarf novae

The authors report the measurement of all observed outbursts of 21 dwarf novae during a three-year interval (JD2442300 - JD2443300), using the data records of the AAVSO. Relationships among the rise

Transiting Exoplanet Survey Satellite (TESS)

The Transiting Exoplanet Survey Satellite (TESS ) will search for planets transiting bright and nearby stars. TESS has been selected by NASA for launch in 2017 as an Astrophysics Explorer mission.
