We investigated the origin of the Planetary Nebula (PN) M 1–16 using narrow-band optical
imaging, and high-and low-resolution optical spectra to perform a detailed morpho …

After performing the morpho-kinematic analysis of the planetary nebula (PN) PC 22, we now
present its nebular and stellar analysis. The plasma investigation relies on the novel use of a …

Many binary companions to the central stars of planetary nebulae (PNe) are found to be
inflated, perhaps indicating that accretion onto the central star might occur during the …

We report high angular resolution Hubble Space Telescope observations of 10 compact
planetary nebulae (PNs). Many interesting internal structures, including multipolar lobes …

We present high-angular-resolution Hubble Space Telescope (HST) optical and near-
infrared imaging of the compact planetary nebula (PN) IRAS 21282+ 5050. Optical images …

We present the first part of an investigation on the planetary nebula (PN) PC 22 that focuses
on the use of deep imaging and high-resolution echelle spectroscopy to perform a detailed …

We carry out an optical morphological and infrared spectral study for two young planetary
nebulae (PNs) Hen 2-158 and Pe 1-1 to understand their complex shapes and dust …

We investigated the origin of the Planetary Nebula (PN) M 1-16 using narrow-band optical
imaging, and high-and low-resolution optical spectra to perform a detailed morpho …

In previous, very deep, optical images of NGC 7293, both a feature that has the morphology
of a bow-shock and one with that of a jet, were discovered in the faint 40 arcmin diameter …

RWT 152 is one of the few known planetary nebulae with an sdO central star. We present
subarcsecond red tunable filter Hα imaging and intermediate-resolution, long-slit …
