Two new white dwarfs with variable magnetic Balmer emission lines

We report the discovery of two apparently isolated stellar remnants that exhibit rotationally modulated magnetic Balmer emission, adding to emerging DAHe class white dwarf stars. While previously discovered members this show Zeeman-split triplet emission features corresponding single field strengths, these new objects significant fluctuations in their apparent strengths with variability phase. The hydrogen lines LP $705{-}64$ broaden from $9.4$ MG $22.2$ over an spin period $72.629$ minutes. Similarly, WD J$143019.29{-}562358.33$ varies $5.8$ $8.9$ its $86.394$-minute rotation period. This brings dwarfs at least five objects, all effective temperatures within $500$ K $8000$ and masses ranging $0.65{-}0.83\,M_{\odot}$.
