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…
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…
HIP 114328: a new refractory-poor and Li-poor solar twin
Jorge Melendez, Lucas Schirbel, TalaWanda R. Monroe +3
[Context]. The standard solar model fails to predict the very low lithium abundance in the Sun, which is much lower than the proto-solar nebula. This Li problem has been debated fo…
