Elemental abundances differences in the massive planet-hosting wide binary HD 196067-68
M. Flores, J. Yana Galarza, P. Miquelarena +6
It has been suggested that small chemical anomalies observed in planet-hosting wide binary systems could be due to planet signatures, where the role of the planetary mass is still…
The largest metallicity difference in twin systems: high-precision abundance analysis of the benchmark pair Krios & Kronos
P. Miquelarena, C. Saffe, M. Flores +7
Aims.We conduct a high-precision differential abundance analysis of the remarkable binary system HD 240429/30 (Krios and Kronos, respectively), whose difference in metallicity is o…
Are Am stars and hot-Jupiter planets related?
C. Saffe, J. Alacoria, P. Miquelarena +8
Am stars are often components of short-period binary systems, where tidal interactions would result in low rotational velocities and help to develop the chemical peculiarities obse…
Searching for lambda Boo stars in binary systems
J. Alacoria, C. Saffe, A. Collado +7
Our goal is to find new candidate lambda Boo stars that belong to binary systems. A detailed abundance determination of some candidates could confirm their true lambda Boo nature,…
