As a parallel result of an IT Project aimed at determining accurate distances to more than 30 planetary nebulae using the extinction-distance method, we report...

Highly collimated bipolar outflows have been detected in the planetary nebula NGC 6572 via ground-based optical imagery and high-resolution long-slit...

IPHAS is an ongoing Hα imaging survey of the North Galactic plane. When completed, it is expected to discover several hundred new Galactic planetary nebulae, in...

We report the first spatially resolved detection of the near-infrared [C I] λ8727 emission from the outer pair of low-ionization structures in the planetary...

The recent infrared detection of fullerenes (C60 and C70) in Planetary Nebulae (PNe) and R Coronae Borealis (RCB) stars offers a beautiful opportunity for...

We present high-resolution (R ~ 15 000) VLT/UVES optical spectra of two planetary nebulae (PNe; Tc 1 and M 1-20) where C60 (and C70) fullerenes have already...

We have studied the amount of diffuse light in two galaxy groups, Leo and HCG 44 through the detection of intragroup planetary nebulae (IGPNe). The emission...

We report the discovery of a planetary nebula centered on the poorly studied symbiotic binary star DT Ser. In a few other symbiotic stars spatially resolved...

We report on the discovery of an eclipsing dwarf nova (DN) inside the peculiar, bilobed nebula Te 11. Modelling of high-speed photometry of the eclipse finds...
