Two of the three “long LPTs” (P≳ 78 min) are associated with orbital periods of WD + MD binaries, while “short LPTs” (P≲ 78 min) generally lack optical counterparts. The ≈78 min division (black line) corresponds to the orbital period minimum of any binary containing a Roche lobe-filling H-rich donor star, seen in the observed period distribution of CVs. The recent discovery of ASKAP J183950.5-075635.0 and its likely association with an NS spin suggests that “long LPTs” are not exclusively associated with WD orbits. Two of the three known “long LPTs” nearly coincide with the CV “period gap”, where accretion is thought to temporarily shut off (blue band).
