We carried out high-sensitivity spectro-polarimetric observations of the central star of the Red Rectangle protoplanetary nebula with the aim of constraining...

Raw data were filtered from outliers and residuals at the orbital period of the satellite. The orbital parameters and the radius of the planet were estimated by...

We present deep images in H alpha +[NII] and [OIII] lambda 5007 of the region around NGC 7027 obtained with the wide field camera (WFC) at the Isaac Newton...

We have acquired imaging of the bipolar outflow M2-9 in the transitions [O III] λ5007, H I λ6563, [N II] λ6584, and [S II] λλ6717, 6731. As a result, we are...

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...
