Chemical inhomogeneities in the Pleiades: signatures of rocky-forming material in stellar atmospheres
Lorenzo Spina, Jorge Meléndez, Andrew R. Casey +2
The aim of Galactic archaeology is to recover the history of our Galaxy through the information encoded in stars. An unprobed assumption of this field is that the chemical composit…
The Solar Twin Planet Search: The age - chromospheric activity relation
Diego Lorenzo-Oliveira, Fabrício C. Freitas, Jorge Meléndez +8
It is well known that the magnetic activity of solar type stars decreases with age, but it is widely debated in the literature whether there is a smooth decline or if there is an e…
Evidences of extragalactic origin and planet engulfment in the metal-poor twin pair HD 134439/HD 134440
Henrique Reggiani, Jorge Meléndez
Recent studies of chemical abundances in metal-poor Halo stars show the existence of different populations, which is important for studies of Galaxy formation and evolution. Here w…
