We have analyzed in detail the discovery measurements of the X-ray burster SAX J1750.8-2900 by the Wide Field Cameras on board BeppoSAX in spring 1997, at a...
A New Catalog of Homogenized Absorption Line Indices for Milky Way Globular Clusters from High-resolution Integrated Spectroscopy
We perform integrated spectroscopy of 24 Galactic globular clusters (GGCs). Spectra are observed from one core radius for each cluster with a high wavelength...
A New Chemo-evolutionary Population Synthesis Model for Early-Type Galaxies. I. Theoretical Basis
We have developed a new stellar population synthesis model designed to study early-type galaxies. It provides optical and near-infrared colors, and line indices...
A New Chemo-evolutionary Population Synthesis Model for Early-Type Galaxies. II. Observations and Results
We present the results of applying a new chemo-evolutionary stellar population model, developed in a previous paper, to new high-quality observational data of...
A New Class of Roche Lobe-filling Hot Subdwarf Binaries
We present the discovery of the second binary with a Roche lobe-filling hot subdwarf transferring mass to a white dwarf (WD) companion. This 56 minute binary...
A new code for automatic determination of equivalent widths: Automatic Routine for line Equivalent widths in stellar Spectra (ARES)
Aims:We present a new automatic code (ARES) for determining equivalent widths of the absorption lines present in stellar spectra. We also describe its use for...
We describe a newly discovered detached M dwarf eclipsing binary system. This system was first observed by the TrES network during a long-term photometry...
A new determination of the solar granulation contrast
The contrast of the photospheric granulation in the centre of the disk at a wavelength of 500 nm has been determined by means of photographs taken during the...
A new discovery space opened by eROSITA. Ionised AGN outflows from X-ray selected samples
Context. In the context of an evolutionary model, the outflow phase of an active galactic nucleus (AGN) occurs at the peak of its activity, once the central...
