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…
High precision abundances in the 16 Cyg binary system: a signature of the rocky core in the giant planet
Marcelo Tucci Maia, Jorge Melendez, Ivan Ramirez
We study the stars of the binary system 16 Cygni to determine with high precision their chemical composition. Knowing that the component B has a detected planet of at least 1.5 Jup…
18 Sco: a solar twin rich in refractory and neutron-capture elements. Implications for chemical tagging
J. Melendez, I. Ramirez, A. I. Karakas +12
We study with unprecedented detail the chemical composition and stellar parameters of the solar twin 18 Sco in a strictly differential sense relative to the Sun. Our study is mainl…
