PLATO input catalogs for technical calibration and fine guidance
René Heller, Chen Jiang, Paz Bluhm +18
A few weeks after launch, the PLATO spacecraft is expected to start its payload commissioning, which will be completed within the first three months of the mission. This phase incl…
Radio observations of the Black Hole X-ray Binary EXO 1846-031 re-awakening from a 34-year slumber
D. R. A. Williams, S. E. Motta, R. Fender +15
We present radio [1.3 GHz MeerKAT, 4-8 GHz Karl G. Jansky Very Large Array (VLA) and 15.5 GHz Arcminute Microkelvin Imager Large Array (AMI-LA)] and X-ray (Swift and MAXI) data fro…
Gaia confirms that SDSS J102915+172927 is a dwarf star
P. Bonifacio, E. Caffau, M. Spite +10
The Gaia Data Release 2 provides a parallax of 0.734+/-0.073 mas for SDSS J102915+172927, currently the most metal-poor known object. This parallax implies that it is dwarf star, r…
The slowly variable star FY Lacertae
Alice Fucci, Fabio Maldarella, Davide Pace +4
Photometric observations and analysis of FY Lac were performed in order to determine the variability characteristics, using measurements taken at Loiano site of Bologna Astronomica…
The solar photospheric abundance of europium. Results from CO5BOLD 3-D hydrodynamical model atmospheres
A. Mucciarelli, E. Caffau, B. Freytag +2
Context. Europium is an almost pure r-process element, which may be useful as a reference in nucleocosmochronology. Aims. To determine the photospheric solar abundance using CO5BOL…
The ESO Large Programme First Stars
P. Bonifacio, J. Andersen, S. Andrievsky +19
In ESO period 65 (April-September 2000) the large programme 165.N-0276, led by Roger Cayrel, began making use of UVES at the Kueyen VLT telescope. Known within the Team and outside…
Analysis of a XMM-Newton Spectrum of the Extremely Hot White Dwarf in Nova V4743 Sgr
Thomas Rauch, Klaus Werner, Marina Orio
Classical novae occur in close binary systems (main-sequence star + white dwarf). V4743 Sgr is a very fast nova exhibiting a X-ray spectrum which is consistent with a view on the o…
The Sgr dSph hosts a metal-rich population
P. Bonifacio, L. Sbordone, G. Marconi +2
We report on abundances of O, Mg, Si, Ca and Fe for 10 giants in the Sgr dwarf spheroidal derived from high resolution spectra obtained with UVES at the 8.2m Kueyen-VLT telescope.…
