The physical structure of planetary nebulae around sdO stars: Abell 36, DeHt 2, and RWT 152★ [PDF]

Monthly Notices of the Royal Astronomical Society, 2014
We present narrow-band Halpha and [OIII] images, and high-resolution, long-slit spectra of the planetary nebulae (PNe) Abell36, DeHt2, and RWT152 aimed at studying their morphology and internal kinematics. These data are complemented with intermediate-resolution, long-slit spectra to describe the spectral properties of the central stars and nebulae ...
