PI: STUART POTTASCH KAPTEYN ASTRONOMICAL INST CoI: Jan Koornneef Kapteyn Astronomical Institute N ------------------------------------------------------------------------------------ 5. Abstract We image three bright planetary nebulae, which have helium rich stellar atmospheres and helium poor nebulae. However, we think that the inner nebulae must be helium rich on a spatial scale that is very accessible with the NIC1 camera on HST. We would expect the images to show a helium-enriched shell on a scale of app. 1". If observed, this would be the first observation of the changeover from hydrogen rich mass loss to helium rich mass loss in planetary nebulae. ------------------------------------------------------------------------------------ Observations Description ------------------------ For each of the three targets, a set of six narrow-band filters will be used. There will be one orbit (or 51 to 58 minutes) for each of the targets. Target acquisition and the DUMP buffer sequences will take 367 and 134 seconds, respectively, for a total of 501 seconds. This leaves app. 426 to 496 seconds for individual exposures.By default, we choose 6 exposures of 384 sec (STEP64, nsum=12), and increase the time for selected filter PAIRS to 512 sec (Step 128, nsum=13).
