Spectroscopic Identification and Population Properties of Cataclysmic Variables from DESI DR1

The Astrophysical Journal Supplement Series
We present a systematic search for cataclysmic variables (CVs) using spectroscopic data from Data Release 1 of the Dark Energy Spectroscopic Instrument. Applying the Bagging-TopPush algorithm, we identified 433 CV candidates and related objects, of which

Negative Superhumps in Cataclysmic Variables Driven by Retrograde Apsidal Disk Precession

The Astrophysical Journal Letters
Negative superhumps (NSHs) are photometric modulations in cataclysmic variables with periods slightly shorter than the orbital period. They are usually attributed to retrograde nodal precession of a tilted accretion disk, although the origin and ...

TESS Light Curves of Cataclysmic Variables. V. Improved or Corrected Orbital Periods of 53 Systems

The Astronomical Journal
The long and continuous high-time-resolution coverage of many stars by the Kepler and TESS space missions permit to explore periodic phenomena with a much higher precision than is possible with terrestrial observations.

Evolution of Cataclysmic Variables with Binary-driven Mass Loss during Nova Eruptions

The Astrophysical Journal
The discrepancies between observations and theoretical predictions of cataclysmic variables (CVs) suggest that there exists unknown angular-momentum-loss mechanism(s) besides magnetic braking and gravitational radiation.

The Inner and Outer Shock Layers of Bow Shocks in Cataclysmic Variables

The Astrophysical Journal Letters
Bow shocks around cataclysmic variables (CVs) have traditionally been identified with a single bright optical arc. This feature has been interpreted as the bow shock formed by the interaction between a sustained outflow and the interstellar medium (ISM).
