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 Candidate Planetary Nebulae in the IPHAS Survey: the Case of Planetary Nebulae with ISM interaction
We present the results of the search for candidate Planetary Nebulae interacting with the interstellar medium (PN-ISM) in the framework of the INT Photometric...
New clues on outburst mechanisms and improved spectroscopic elements of the black hole binary V4641 Sagittarii*
We present spectroscopic observations of the black hole binary V4641 Sagittarii, obtained between 2004 July 4 and 2005 March 28, which cover the minor outburst...
New Clues on the Extended He II Ionization in IZw18 from GTC/MEGARA and JWST/MIRI
IZw18 is one of the lowest-metallicity star-forming galaxies known at z ∼ 0, considered a unique local analogue of the first galaxies. The origin of its hard...
We present high-angular-resolution optical I-band imaging of 451 late K to mid-M nearby stars. These observations have been performed with Astralux and FastCam...
New constraints on neutron star models of gamma ray bursts. I - EXOSAT observations of two gamma ray burst error boxes
Two EXOSAT observations of gamma-ray burst error boxes and their possibly associated optical transients are discussed. No point source was detected in either...
New constraints on the central mass contents of Omega Centauri from combined stellar kinematics and pulsar timing
Aims. We performed a combined analysis of stellar kinematics with line-of-sight accelerations of millisecond pulsars (MSPs) to probe the mass content of Omega...
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 Future Evaporation of the Young Exoplanets in the V1298 Tau System
Transiting planets at young ages are key targets for improving our understanding of the evolution of exo-atmospheres. We present results of a new X-ray...
