抄録（英）
Circumstellar disks seem to be present at every stage of stellar evolution, beginning from proto-stellar cores, through evolutionary advanced stages, like first-ascent, asymptotic giant branch (AGB) stars, post-AGB objects, and ending on isolated white dwarfs (WDs). WDs are relatively recent addition to this track. The nature of disks around evolutionary advanced objects is still a matter of debate. Disks around pre-main sequence stars are very likely to be sites of planets formation. We do not know yet whether protoplanets can be formed in disks around evolutionary advanced stars. Therefore, understanding the creation, evolution and survival of such disks is a matter of primary importance. We propose a study of known disks around isolated white dwarfs and of possible disks around binary systems that contain WD component with the SAFARI instrument on board of the SPICA satellite.
