The AstraLux Large M-dwarf Survey
Listed in IVOA Registry (Virtual Observatory)
These tables contain the results from a multiplicity survey of 701 M-type and 60 K-type stars (among which 182 new and 37 previously known companions were detected in 205 systems) using the Lucky Imaging cameras AstraLux Norte at the Calar Alto 2.2m and AstraLux Sur at the ESO NTT.
Description
Most of the targets have been observed during two or more epochs, and could be confirmed as physical companions through common proper motion, often with orbital motion being confirmed in addition.
One table lists general properties of all the stars in the sample, another the observational parameters of each confirmed or suspected binary, a third lists the derived physical parameters of each confirmed or suspected binary, the fourth lists astrometric data points of all binary candidates for which multiple epochs have been collected (also including literature measurements for previously resolved binaries) and a final table lists observational properties of confirmed or suspected background stars.
