Ritter & Kolb Cataclysmic Variable Catalog
Credit: NASA/ESA/Hubble
Part of the Astronomy Datasets and Variable Stars & Transients collections on Hugging Face.
The Ritter & Kolb catalog of cataclysmic variables (CVs), sourced from NASA HEASARC. Currently 1,168 CVs with 51 attributes.
Dataset description
Cataclysmic variables (CVs) are binary star systems in which a white dwarf accretes matter from a low-mass companion star (typically a red dwarf) that overflows its Roche lobe. The infalling material forms an accretion disk around the white dwarf, producing dramatic brightness variations across timescales from seconds to decades. CVs are classified into several subtypes based on their outburst behavior and magnetic field strength:
- Dwarf novae (DN): exhibit quasi-periodic outbursts of 2-8 magnitudes caused by thermal instabilities in the accretion disk. Includes SU UMa, U Gem, and Z Cam subtypes.
- Classical novae (N): undergo thermonuclear explosions on the white dwarf surface when accreted hydrogen reaches a critical mass, brightening by 6-19 magnitudes.
- Polars (AM Her): strongly magnetic white dwarfs (B ~ 10-230 MG) where the magnetic field channels accretion directly onto the poles, preventing disk formation.
- Intermediate polars (DQ Her): moderately magnetic white dwarfs (B ~ 1-10 MG) with a truncated accretion disk and magnetically channeled inner flow.
- Nova-like variables (NL): high mass-transfer rate systems in a persistent bright state without the outburst cycles of dwarf novae.
The Ritter & Kolb catalog is the standard reference catalog for CV research, containing orbital periods, spectral types, magnitudes, and classifications for the known CV population. This dataset is essential for population studies, period distribution analysis, and understanding the evolution of compact binary systems.
