Cataclysmic variable orb. periods from Gaia phot.
Listed in IVOA Registry (Virtual Observatory)
The 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.
Description
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.
