Wide sigma Orionis binaries resolved by UKIDSS
J. A. Caballero, I. Novalbos, T. Tobal +1
In spite of its importance for the study of star formation at all mass domains, the nearby young sigma Orionis cluster still lacks a comprehensive survey for multiplicity. We try t…
Collaborating with "professional" amateurs: low-mass stars in fragile multiple system
J. A. Caballero, J. Genebriera, T. Tobal +7
The boundary between professional and amateur astronomers gets narrower and narrower. We present several real examples, most of them published in refereed journals, of works result…
Cool dwarfs in wide multiple systems. Paper 3: Two common-proper-motion, late-type stars separated by over 11 arcmin
J. A. Caballero, J. Genebriera, F. X. Miret +2
LP 209-28 and LP 209-27 have similar proper motions as tabulated by several catalogues. Using seven astrometric epochs spanning 59 years, we confirm a common tangential velocity by…
The magnetically-active, low-mass, triple system WDS 19312+3607
J. A. Caballero, D. Montes, A. Klutsch +5
Aims: We investigated in detail the system WDS 19312+3607, whose primary is an active M4.5Ve star previously thought to be young (tau ~ 300-500 Ma) based on high X-ray luminosity.…
Preliminary results on a Virtual Observatory search for companions to Luyten stars
J. A. Caballero, F. X. Miret, J. Genebriera +3
The Aladin sky atlas of the Virtual Observatory has shown to be a powerful and easy-handling tool for the discovery, confirmation, and characterisation of high proper-motion, multi…
