CNO behaviour in planet-harbouring stars. II. Carbon abundances in stars with and without planets using the CH band

L. Suárez-Andrés, G. Israelian, J. I. González Hernández +4

Context. Carbon, oxygen and nitrogen (CNO) are key elements in stellar formation and evolution, and their abundances should also have a significant impact on planetary formation an…

A Comparison of Stellar Elemental Abundance Techniques and Measurements

Natalie R. Hinkel, Patrick A. Young, Michael D. Pagano +15

Stellar elemental abundances are important for understanding the fundamental properties of a star or stellar group, such as age and evolutionary history, as well as the composition…

The Gaia-ESO Survey: Inhibited extra mixing in two giants of the open cluster Trumpler 20?

R. Smiljanic, E. Franciosini, S. Randich +32

We report the discovery of two Li-rich giants, with A(Li) ~ 1.50, in an analysis of a sample of 40 giants of the open cluster Trumpler 20 (with turnoff mass ~ 1.8 Msun). The cluste…

K2-110 b - a massive mini-Neptune exoplanet

H. P. Osborn, A. Santerne, S. C. C. Barros +33

We report the discovery of the exoplanet K2-110 b (previously EPIC212521166b) from K2 photometry orbiting in a 13.8637d period around an old, metal-poor K3 dwarf star. With a V-ban…

The Gaia-ESO Survey: A lithium-rotation connection at 5 Myr?

J. Bouvier, A. Lanzafame, L. Venuti +37

We investigate here the lithium content of young low-mass stars in the 5~Myr-old star forming region NGC~2264 and its relationship with rotation. We combine lithium equivalent widt…
