Scientific paper

We propose to search for infrared excesses around a sample of ultramassive white dwarfs. Several lines of evidence suggest that these stars may be the result of the merger of close white dwarf binaries. Such mergers are likely to leave behind circumstellar disks rich in heavy elements. Our program is designed to detect the resulting dust disk through the reprocessed stellar light. Detection of such systems would suggest a new niche in the extrasolar planet parameter space - the possibility of the formation of second generation planetary systems.
