Testing the accretion scenario of lambda Boo stars
J. Alacoria, C. Saffe, M. Jaque Arancibia +5
Our aim is to test the accretion scenario of lambda Boo stars. This model predicts that a binary system with two early-type stars passing through a diffuse cloud should both displa…
Chemical analysis of early-type stars with planets
C. Saffe, P. Miquelarena, J. Alacoria +6
Aims. To explore the chemical pattern of early-type stars with planets, searching for a possible signature of planet formation. In particular, we study a likely relation between th…
Detecting prolonged activity minima in binary stars. The case of Ret
M. Flores, M. Jaque Arancibia, R. V. Ibañez Bustos +7
Context. It is well known that from 1645 to 1715 solar activity was notably low and the number of sunspots was extremely reduced. This epoch is known as the Maunder Minimum (MM). T…
KELT-17: a chemically peculiar Am star and a hot-Jupiter planet
C. Saffe, P. Miquelarena, J. Alacoria +6
Context. The detection of planets orbiting chemically peculiar stars is very scarcely known in the literature. Aims. To determine the detailed chemical composition of the remarkabl…
