We have investigated the properties of the diffuse light in the Virgo Cluster core region, based on the detection of intracluster planetary nebulae (PNs) in...

We use a high-resolution collisionless simulation of a Virgo-like cluster in a ΛCDM cosmology to determine the velocity and clustering properties of the diffuse...

We use a large grid of photoionization models that are representative of observed planetary nebulae (PNe) to derive ionization correction factors (ICFs) for...

Context: The study of symbiotic stars is essential to understand important aspects of stellar evolution in interacting binaries. Their observed population in...

Context. The IPHAS Hα survey provides a rich database to search for emission-line sources in the northern Galactic plane. Aims: We are systematically searching...

Aims: The determination of reliable distances to planetary nebulae (PNe) is a major difficulty in the study of this class of objects in the Galaxy. The...

A planetary nebula has been discovered in the course of the INT/WFC Photometric Hα Survey (IPHAS) of the northern galactic plane. It is located near the...

The onset of forbidden line emission in the spectrum of a proto-planetary nebula has been detected for the first time in the lapse of only two years. IRAS 06562...

The identification of two new southern planetary nebulae, IRAS 16455-3455 and IRAS 15154-5258, via low resolution spectroscopy, is reported. IRAS 16455-3455 is...
