cds-question@unistra.frcataclysmic-variable-starsvariable-starsabsolute-magnitudetwo-color-diagramsvisible-astronomysurveysThe orbital-period (Porb) gap in the population of cataclysmic variables (CVs) informs the theoretical narrative of CV evolution, yet a complete understanding of the driving angular momentum loss mechanisms above and below this gap remains elusive. Here we identify, for standard CVs, a new, apparently monotonic relationship between quiescent color (G_BP_-G_RP_), absolute magnitude (M_G_), and Porb (between 70 minutes and 8hr) revealed in Gaia DR2 and EDR3. We show that Porb increases in the color-absolute-magnitude diagram roughly orthogonally to the white dwarf and main sequences. We find the orbital-period-color-absolute-magnitude relationship to be stable across different CV subtypes: dwarf novae, intermediate polars, polars, and novalike systems. We place our findings in context with the known semiempirical donor sequence for CVs and find a dependence between color and MG for a given Porb specifically for dwarf novae and intermediate polars above the period gap. These relations have the potential to inform a more complete picture of CV evolution.2022ApJ...938...46Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/938/46CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/vsx : AAVSO International Variable Star Index VSX (Watson+, 2006-)I/345 : Gaia DR2 (Gaia Collaboration, 2018)I/350 : Gaia EDR3 (Gaia Collaboration, 2020)I/352 : Distances to 1.47 billion stars in Gaia EDR3 (Bailer-Jones+, 2021)J/ApJS/194/28 : The evolution of cataclysmic variables (Knigge+, 2011)J/other/NewA/34.234 : Gal. cataclysmic variables distances (Ozdonmez+, 2015)J/AJ/154/252 : A VLA survey of magnetic CVs.
