Context. It has been recently found that the characteristic photometric parameters of anti-truncated discs in S0 galaxies follow tight scaling relations. Aims: We investigate whether similar scaling relations are satisfied by galaxies of other morphological types. Methods: We have analysed the trends in several photometric planes relating the

During the last decade (starting in 2005), the OAS Project has been run, with the support of the Spanish research agencies. Within its framework, research on cultural astronomy has been developed for a series of ancient cultures from the Atlantic Islands to the Arabian Peninsula with the Meditterranean Sea as the pricipal axis of the project. A

As part of an investigation into the high-mass end of the initial mass-final mass relation we performed a search for new white dwarf members of the nearby (172.4 pc), young (80-90 Myr) α Persei open star cluster. The photometric and astrometric search using the United Kingdom InfraRed Telescope (UKIRT) Infrared Deep Sky Survey and SuperCOSMOS sky

We investigated the absolute age of the Galactic globular cluster M71 (NGC 6838) using optical ground-based images (u\prime ,g\prime ,r\prime ,i\prime ,z\prime ) collected with the MegaCam camera at the Canada–France–Hawaii Telescope (CFHT). We performed a robust selection of field and cluster stars by applying a new method based on the 3D (r\prime

The study of stellar parameters of planet-hosting stars, such as metallicity and chemical abundances, help us to understand the theory of planet formation and stellar evolution. In this poster, we present a catalog of accurate stellar atmospheric parameters and iron abundances for a sample of 257 K and G field evolved stars that are being surveyed

We present high spatial resolution ($\approx60$--90 milliarcseconds) images of the molecular hydrogen emission in the Planetary Nebula (PN) NGC~2346.The data were acquired during the System Verification of the Gemini Multi-Conjugate Adaptive Optics System (GeMS) + Gemini South Adaptive Optics Imager GSAOI).At the distance of NGC~2346, 700 pc, the
