Abundances of Light Metals in Field Stars with Metallicity Range - 1.2< [Fe/H]< + 0.3
High resolution, high S:N spectra are used to determine the abundances of Fe, Ni, Ca, Al and Si in 25 field dwarfs with -1.2 [Fe/H] +0.3. The authors find...
Ground-based observations were used to analyze the CMD over a wide spatial field in the B and V bands and to estimate the atmospheric parameters of the...
Table 8 contains the equatorial coordinates, the atmospheric parameters measured on UVES spectra, UBVI_C photometry from WFI@2.2m telescope and infrared JHK...
Accounting for convective blue-shifts in the determination of absolute stellar radial velocities.
For late-type non-active stars, gravitational redshifts and convective blueshifts are the main source of biases in the determination of radial velocities. If...
We report on the X-ray aperiodic timing analysis of two accreting millisecond pulsars: XTE J1807-294 and IGR J00291+5934. On the one hand, we discovered in XTE...
Accreting white dwarfs as probes of compact binary evolution
In the last 20 years, the study of compact interacting binaries has led to two major breakthroughs in astrophysics: the discovery of dark energy and the first...
Accretion and winds in neutron star low-mass X-ray binaries
In recent decades, observations of the X-ray and radio continuum have been instrumental in studying the coupling between accretion and ejection processes in low...
