The Solar Twin Planet Search. I. Fundamental parameters of the stellar sample
I. Ramirez, J. Melendez, J. Bean +10
We are carrying out a search for planets around a sample of solar twin stars using the HARPS spectrograph. The goal of this project is to exploit the advantage offered by solar twi…

A possible signature of terrestrial planet formation in the chemical composition of solar analogs
I. Ramirez, M. Asplund, P. Baumann +2
Recent studies have shown that the elemental abundances in the Sun are anomalous when compared to most (about 85%) nearby solar twin stars. Compared to its twins, the Sun exhibits…

Lithium depletion in solar-like stars: no planet connection
Patrick Baumann, Iván Ramírez, Jorge Meléndez +2
We have determined precise stellar parameters and lithium abundances in a sample of 117 stars with basic properties very similar to the Sun. This sample selection reduces biasing e…
