The major purpose of this paper is to investigate the nature of planetary nebulae (PNe) candidates in the southern hemisphere, taken from an internal list. We...

Ongoing and future optical and near-infrared surveys focused on the study of the Galactic plane are briefly presented. Their potential is illustrated by the...

We present the discovery of a previously unknown member of the immediate solar neighbourhood, DENIS-P J104814.7-395606.1 (hereafter DENIS 1048-39), identified...

O and early B stars are at the apex of galactic ecology, but in the Milky Way, only a minority of them may yet have been identified. We present the results of a...

By observing the high Galactic latitude equatorial sky in drift-scan mode with the QUEST (Quasar Equatorial Survey Team) Phase 1 camera, we have collected...

Aims: We aim to develop an efficient method to search for late-type subdwarfs (metal-depleted dwarfs with spectral types ≥M5) to improve the current statistics...

Based on observations made with ESO Telescopes at the La Silla Paranal Observatory under programme ID 084.C-0928A.Based on observations made with the Nordic...

Aims: The aim of the project is to improve our knowledge of the low-mass and low-metallicity population to investigate the influence of metallicity on the...

Aims: We search for very small-diameter galactic planetary nebulae (PNe) representing the earliest phases of PN evolution. The IPHAS catalogue of Hα-emitting...
