Discovery of a 21 Myr old stellar population in the Orion complex
Janez Kos, Joss Bland-Hawthorn, Martin Asplund +12
The Orion complex is arguably the most studied star-forming region in the Galaxy. While stars are still being born in the Orion nebula, the oldest part was believed to be no more t…
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…
Gaia DR2 view of the Lupus V-VI clouds: the candidate diskless young stellar objects are mainly background contaminants
C. F. Manara, T. Prusti, F. Comeron +10
Extensive surveys of star-forming regions with Spitzer have revealed populations of disk-bearing young stellar objects. These have provided crucial constraints, such as the timesca…
The Gaia-ESO Survey: the origin and evolution of s-process elements
L. Magrini, L. Spina, S. Randich +45
Several works have found an increase of the abundances of the s-process neutron-capture elements in the youngest Galactic stellar populations, giving important constraints to stell…
The Gaia-ESO Survey: kinematical and dynamical study of four young open clusters
L. Bravi, E. Zari, G. G. Sacco +32
Context. The origin and dynamical evolution of star clusters is an important topic in stellar astrophysics. Several models have been proposed to understand the formation of bound a…
The Chemical Homogeneity of Sun-like Stars in the Solar Neighborhood
Megan Bedell, Jacob L. Bean, Jorge Melendez +9
The compositions of stars are a critical diagnostic tool for many topics in astronomy such as the evolution of our Galaxy, the formation of planets, and the uniqueness of the Sun.…
