Euclid Quick Data Release (Q1) Ultracool dwarfs in the Euclid Deep Field North
A. Mohandasan, R. L. Smart, C. Reylé +176
Ultracool dwarfs (UCDs) encompass the lowest mass stars and brown dwarfs, defining the stellar substellar boundary. They have significant potential for advancing the understanding…
Euclid: High-precision imaging astrometry and photometry from Early Release Observations. I. Internal kinematics of NGC 6397 by combining Euclid and Gaia data
M. Libralato, L. R. Bedin, M. Griggio +175
The instruments at the focus of the Euclid space observatory offer superb, diffraction-limited imaging over an unprecedented (from space) wide field of view of 0.57 deg. This e…
Stellar chromospheric activity of 1,674 FGK stars from the AMBRE-HARPS sample I. A catalogue of homogeneous chromospheric activity
J. Gomes da Silva, N. C. Santos, V. Adibekyan +9
We present a catalogue of homogeneous determined chromospheric emission (CE), stellar atmospheric parameters and ages for 1,674 FGK main sequence (MS), subgiant, and giant stars. T…
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,…
