The temporal evolution of neutron-capture elements in the Galactic discs
Lorenzo Spina, Jorge Meléndez, Amanda I. Karakas +8
Important insights into the formation and evolution of the Galactic disc(s) are contained in the chemical compositions of stars. We analysed high-resolution and high signal to nois…
iota Horologii is unlikely to be an evaporated Hyades star
I. Ramirez, D. Yong, E. Gutierrez +3
We present a high-precision chemical analysis of iota Horologii, a planet-host field star thought to have formed in the Hyades. Elements with atomic number 6<=Z<=30 have abundances…
On the Iron Abundance Anomaly in K-dwarf and Hyades Stars
Patrick D. Aleo, Alexander C. Sobotka, Ivan Ramirez
Using standard 1D-LTE model atmosphere analysis, we provide an in-depth investigation of iron abundance as derived from neutral and singly ionization iron lines (Fe {\scriptsize{I,…
Spectroscopic binaries in the Solar Twin Planet Search program: from substellar-mass to M dwarf companions
Leonardo A. dos Santos, Jorge Meléndez, Megan Bedell +6
Previous studies on the rotation of Sun-like stars revealed that the rotational rates of young stars converge towards a well-defined evolution that follows a power-law decay. It se…
