The lithium-rotation connection in the newly discovered young stellar stream Psc-Eri (Meingast 1)
J. Arancibia-Silva, J. Bouvier, A. Bayo +4
Context. As a fragile element, lithium is a sensitive probe of physical processes occurring in stellar interiors. Aims. We aim at investigating the relationship between lithium abu…
Metallicity, temperature, and gravity scales of M subdwarfs
N. Lodieu, F. Allard, C. Rodrigo +5
The aim of the project is to define a metallicity/gravity/temperature scale vs spectral types for metal-poor M dwarfs. We obtained intermediate-resolution ultraviolet (R~3300), opt…
The extended halo of NGC 2682 (M 67) from Gaia DR2
R. Carrera, M. Pasquato, A. Vallenari +8
Context: NGC 2682 is a nearby open cluster, approximately 3.5 Gyr old. Dynamically, most open clusters should dissolve on shorter timescales, of ~ 1 Gyr. Having survived until now,…
Proper motions of young stars in Chamaeleon. I. A Virtual Observatory study of spectroscopically confirmed members
Belén López Martí, Francisco Jiménez-Esteban, Amelia Bayo +3
(abridged) We want to provide further evidence of the origin of the proposed stellar members of Chamaeleon and to identify interlopers from the foreground εCha and ηCha association…
