Extended X-ray emission from the planetary nebula BD +30°3639.
LEAHY D.A., KWOK S. and YIN D.
Abstract (from CDS):
We report the discovery of extended X-ray emission from the planetary nebula BD +30°3639. Analysis of the ROSAT HRI image shows clearly that BD +30°3639 has extended X-ray emission which is well fitted with a Gaussian source of σ=1".7-2".8 (95.4% confidence interval). This size is consistent with being the same as that of the optical nebula as imaged by the Hubble Space Telescope. BD +30°3639 therefore represents the best case for the detection of a shocked-stellar-wind bubble in planetary nebulae.
