Extremely fast orbital decay of the black hole X-ray binary Nova Muscae 1991
J. I. González Hernández, L. Suárez-Andrés, R. Rebolo +1
We present new medium-resolution spectroscopic observations of the black hole X-ray binary Nova Muscae 1991 taken with X-Shooter spectrograph installed at the 8.2m-VLT telescope. T…
CNO behaviour in planet-harbouring stars. I Nitrogen abundances in stars with planets
L. Suárez-Andrés, G. Israelian, J. I. González Hernández +4
Carbon, nitrogen, and oxygen (CNO) are key elements in stellar formation and evolution, and their abundances should also have a significant impact on planetary formation and evolut…
Ret, its debris disk, and its lonely stellar companion Ret. Different trends for different spectra
V. Adibekyan, E. Delgado-Mena, P. Figueira +8
Several studies have reported a correlation between the chemical abundances of stars and condensation temperature (known as Tc trend). Very recently, a strong Tc trend was reported…
Identifying the best iron-peak and -capture elements for chemical tagging: The impact of the number of lines on measured scatter
V. Adibekyan, P. Figueira, N. C. Santos +9
The main goal of this work is to explore which elements carry the most information about the birth origin of stars and as such that are best suited for chemical tagging. We explore…
Chemical abundances of the secondary star in the Neutron star X-ray binary Cygnus X-2
L. Suárez-Andrés, J. I. González Hernández, G. Israelian +2
We present UES@WHT high-resolution spectra of the low-mass X-ray binary (LMXB) Cygnus X-2. We have derived the stellar parameters of the secondary star using minimisation p…
