		| Abstract: | 
		We are investigating "the transition period" and minimum periods of the evolution of compact systems including a NS. The implications of this kind of study for the understanding of the so called "non flickerers" discovered by Cool et al.(1998) and Taylor et al.(2001) and identified as He-WDs, are briefly discussed. |
