We combine new Lucky Imaging astrometry from NTT/AstraLux Sur with already published astrometry from the AstraLux Large M-dwarf Multiplicity Survey to compute orbital elements and individual masses of the 2MASS J10364483+1521394 triple system belonging to the Ursa-Major moving group. The system consists of one primary low-mass M-dwarf orbited by two less massive companions, for which we determine a combined dynamical mass of $M_{\rm{B}+\rm{C}}= 0.48 \pm 0.14\ M_\odot$. We show from the…

Speckle imaging produces diffraction-limited images from ground-based telescopes. Recent advancements in detectors such as electron-multiplying CCDs (EMCCDs), have spawned a resurgence of this

Improving dynamical mass constraints for intermediate-period substellar companions using Gaia DR2

The relationship between luminosity and mass is of fundamental importance for direct imaging studies of brown dwarf and planetary companions to stars. In principle this can be inferred from

Dynamical masses of M-dwarf binaries in young moving groups

Low-mass stars exhibit substantial pre-main sequence evolution during the first ∼100 Myr of their lives. Thus, young M-type stars are prime targets for isochronal dating, especially in young moving
