Multiplicity of stellar systems in the solar neighbourhood, wide binaries, and planet-hosting stars
Javier González-Payo
This doctoral thesis studies stellar multiplicity in the solar neighborhood (d < 10 pc) and in systems hosting planets (d < 100 pc). Using data from the Washington Double Star Cata…

CARMENES input catalogue of M dwarfs IX. Multiplicity from close spectroscopic binaries to ultra-wide systems
C. Cifuentes, J. A. Caballero, J. González-Payo +12
Multiplicity studies greatly benefit from focusing on M dwarfs because they are often paired in a variety of configurations with both stellar and substellar objects, including exop…

Wide companions to M and L subdwarfs with Gaia and the Virtual Observatory
J. González-Payo, M. Cortés-Contreras, N. Lodieu +3
The aim of the project is to identify wide common proper motion companions to a sample of spectroscopically confirmed M and L metal-poor dwarfs (also known as subdwarfs) to investi…
