CNO behaviour in planet-harbouring stars. II. Carbon abundances in stars with and without planets using the CH band
L. Suárez-Andrés, G. Israelian, J. I. González Hernández +4
Context. Carbon, oxygen and nitrogen (CNO) are key elements in stellar formation and evolution, and their abundances should also have a significant impact on planetary formation an…
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…
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…
