By tracing the distribution of cool dust in the extended envelopes ofpost-AGB stars and (proto)-planetary nebulae ((P)PNe) we aim to recover, orconstrain, the mass loss history experienced by these stars in their recentpast. The Far-Infrared Surveyor (FIS) instrument on board the AKARI satellitewas used to obtain far-infrared maps for a selected sample of post-AGB starsand (P)PNe. We derived flux densities (aperture photometry) for 13 post-AGBstars and (P)PNe at four far-infrared wavelengths (60, 90, 140, and 160 um).Radial (azimuthally averaged) profiles are used to investigate the presence ofextended emission from cool dust. No (detached) extended emission is detectedfor any target in our sample at levels significant with respect to backgroundand cirrus emission. Only IRAS 21046+4739 reveals tentative excess emissionbetween 30 and 130". Estimates of the total dust and gas mass from the obtainedmaps indicate that the envelope masses of these stars should be large in orderto be detected with the AKARI FIS. Imaging with higher sensitivity and higherspatial resolution is needed to detect and resolve, if present, any coolcompact or extended emission associated with these evolved stars.
