A 34'x34' field centred on the spiral galaxy M 81 has been searched for emission-line objects using the prime focus wide field camera (WFC) of the 2.54 m Isaac...
New constraints on the formation and settling of dust in the atmospheres of young M and L dwarfs
Context. Gravity modifies the spectral features of young brown dwarfs (BDs). A proper characterization of these objects is crucial for the identification of the...
New constraints on the membership of the T dwarf S Ori 70 in the σ Orionis cluster
Aims:The nature of S Ori 70 (S Ori J053810.1-023626), a faint mid-T type object found towards the direction of the young σ Orionis cluster, is still under...
New constraints on the presence of debris disks around G 196-3 B and VHS J125601.92-125723.9 b
Context. The existence of warm (protoplanetary) disks around very young isolated planetary and brown dwarf mass objects is known based on near- and mid-infrared...
New constraints on the structure of the nuclear stellar cluster of the Milky Way from star counts and MIR imaging
Context. The Milky Way nuclear star cluster (MWNSC) is a crucial laboratory for studying the galactic nuclei of other galaxies, but its properties have not been...
New database for a sample of optically bright lensed quasars in the northern hemisphere
In the framework of the Gravitational LENses and DArk MAtter (GLENDAMA) project, we present a database of nine gravitationally lensed quasars (GLQs) that have...
New delta Scuti variable in the Pleiades: HD 23628.
We report here the discovery of very low amplitude oscillations in the Pleiades star HD 23628. The 14-nights high quality light curve designates HD 23628 as a...
New estimates of the contribution of Wolf-Rayet stellar winds to the Galactic 26Al
We present new yields of 26Al from Wolf-Rayet stellar winds based on rotating stellar models which account well for numerous observed properties of massive...
New groups of planetary nebulae with peculiar dust chemistry towards the Galactic bulge
Aims: We investigate Galactic bulge planetary nebulae without emission-line central stars for which peculiar infrared spectra have been obtained with the...
