Far-Infrared ISO Limits on Dust Disks around Millisecond Pulsars

Abstract

We report 60 and 90 micron observations of 7 millisecond pulsars with the ISOPHOT instrument and describe our analysis procedures. No pulsars were detected, and typical (3σ) upper limits are 150 mJy. We combine our results with others in the literature and use them to place constraints on the existence of protoplanetary or dust disks around millisecond pulsars.
