New, late-type spectroscopic binaries with X-ray emission
A. Frasca, G. Catanzaro, I. Busà +6
In this paper we present a spectroscopic study of six double-lined binaries, five of which were recently discovered in a high-resolution spectroscopic survey of optical counterpart…
Gaia Data Release 3. Astrometric binary star processing
Jean-Louis Halbwachs, Dimitri Pourbaix, Frédéric Arenou +6
Context.The Gaia Early Data Release 3 contained the positions, parallaxes and proper motions of 1.5 billion sources, among which some did not fit well the "single star" model. Bina…
Masses of the components of SB2 binaries observed with Gaia. V. Accurate SB2 orbits for 10 binaries and masses of the components of 5 binaries
Jean-Louis Halbwachs, Flavien Kiefer, Yveline Lebreton +8
Double-lined spectroscopic binaries (SB2s) are one of the main sources of stellar masses, as additional observations are only needed to give the inclinations of the orbital planes…
Discovery of new members of the nearby young stellar association in Cepheus
A. Klutsch, A. Frasca, P. Guillout +4
Young field stars are hardly distinguishable from older ones because their space motion rapidly mixes them with the stellar population of the Galactic plane. Nevertheless, a carefu…
Contemporaneous broad-band photometry and H observations of T Tauri stars
A. Frasca, D. Montes, J. M. Alcalá +2
The study of contemporaneous variations of the continuum flux and emission lines is of great importance to understand the different astrophysical processes at work in T Tauri stars…
A Spectroscopic Survey of the Youngest Field Stars in the Solar Neighborhood. II. The optically faint sample
A. Frasca, P. Guillout, A. Klutsch +5
Star formation in the solar neighborhood is mainly traced by young stars in open clusters, associations and in the field, which can be identified by their X-ray emission. The deter…
