Session 53 - SNs, Planetaries and Circumstellar Disks.
Display session, Wednesday, June 10
We report discovery of extended X--ray emission from the planetary nebulae BD+303639. BD+303639 was the target of a ROSAT HRI observation with the goal of resolving the x--ray emission. Analysis of the ROSAT HRI image shows clearly that BD+303639 has extended x-ray emission which can be fit with a Gaussian with a \sigma of 2.6 arcseconds (after correction for the HRI point spread function). This size is the same as that of the optical nebulae, as recently imaged in HST observations.
