An hot disk surrounding a millisecond radio pulsar in a binary system is identified in optical spectroscopic observations. The disk existed in a year and then disappeared before 2003 January. The disappearance of the disk was likely caused by its interaction with the radio pulsar. Different scenarios have been suggested for the interaction between pulsars and their disks. This binary system thus serves as a rare case that we would like to study in detail, helping our understanding of the interaction. Here we propose Spitzer/IRAC imaging of the binary system. We seek to detect excess emission from the remnant of the disk. A detection would suggest that the disk was pushed away and the remnant would exist as a circumbinary disk. For a non-detection, we would set a constraint on the existence of any dust material in the system, helping our near-future studies of this rare system at optical and infrared wavelengths.
