We detect some objects that can be classified as planetary nebulae candidate s (PNc), using images of a southern region of M 33. This search is the deepest one...
Planetary nebulae (PNe) have been used to trace the chemical evolution of galaxies, not only in the Milky Way (Esteban & Peimbert 1995 and references therein)...
Planetary nebula LoTr5: hints of a possible third companion in a long-period binary central star
LoTr 5 is a planetary nebula with an unusual long-period binary central star. The pair consists of a rapidly rotating G-type star and a hot star, which is...
Long slit spectrophotometry of 13 bipolar planetary nebulae has been used to study their physical and chemical properties. In each nebula, one to seven...
We have created a new Planetary Nebulae (PNe) catalogue by using astrometric and photometric data from Gaia EDR3. Firstly, we have developed an algorithm that...
Planetary nebulae search in the outskirts of M33: looking for the farthest candidates
The nearby disc galaxy M33 is one of the best laboratories for testing chemical evolution models in galaxies and for understanding disc formation mechanisms. In...
Planetary Nebulae: What Can They Tell Us About Close Binary Evolution?
It is now clear that a binary pathway is responsible for a significant fraction of planetary nebulae, and the continually increasing sample of known central...
