The superoutburst duration versus orbital period relation for AM CVn stars.

CANNIZZO J.K. and RAMSAY G.

Abstract (from CDS):

We examine the relationship between superoutburst duration tdur and orbital period Porb in AM CVn ultra-compact binary systems. We show that the previously determined steep relation derived by Levitan et al. was strongly influenced by the inclusion of upper limits for systems with a relatively long orbital period in their fit. Excluding the upper limit values and including tdur values for three systems at long Porb that were not considered previously, then dlog(tdur)/dlog(Porb) is flat as predicted by Cannizzo & Nelemans.
