Dynamical masses of M-dwarf binaries in young moving groups: I - The case of TWA 22 and GJ 2060
L. Rodet, M. Bonnefoy, S. Durkan +48
Evolutionary models are widely used to infer the mass of stars, brown dwarfs, and giant planets. Their predictions are thought to be less reliable at young ages ( 200 Myr) and i…
Characterisation of close visual binaries from the AstraLux Large M Dwarf Survey
C. Bergfors, W. Brandner, M. Bonnefoy +4
We present VLT/SINFONI J, H+K spectra of seven close visual pairs in M dwarf binary/triple systems, discovered or observed by the AstraLux M dwarf survey. We determine the spectral…
Orbital Monitoring of the AstraLux Large M-dwarf Multiplicity Sample
Markus Janson, Carolina Bergfors, Wolfgang Brandner +6
Orbital monitoring of M-type binaries is essential for constraining their fundamental properties. This is particularly useful in young systems, where the extended pre-main sequence…
The AstraLux Multiplicity Survey: Extension to Late M-dwarfs
Markus Janson, Carolina Bergfors, Wolfgang Brandner +4
The distribution of multiplicity among low-mass stars is a key issue to understanding the formation of stars and brown dwarfs, and recent surveys have yielded large enough samples…
Characterization of the Benchmark Binary NLTT 33370
J. E. Schlieder, M. Bonnefoy, T. M. Herbst +16
We report the confirmation of the binary nature of the nearby, very low-mass system NLTT 33370 with adaptive optics imaging and present resolved near-infrared photometry and integr…
Stellar companions to exoplanet host stars: Lucky Imaging of transiting planet hosts
Carolina Bergfors, Wolfgang Brandner, Sebastian Daemgen +7
Observed properties of stars and planets in binary/multiple star systems provide clues to planet formation and evolution. We extended our survey for visual stellar companions to th…
