SUMMARY:Conference / Symposium:Multiplicity: from binary to planetary formation
DESCRIPTION:Most stars in our galaxy form in systems\, whose architecture and composition are fossil records of\ntheir formation and evolution. Particularly for brown dwarfs and exoplanets\, belonging to a system is\na key advantage for their characterization and the calibration of evolutionary and atmospheric\nmodels. In this talk\, I will provide a status update on the multiplicity statistics within the 20pc\ncensus\, and lay out multiple ongoing efforts to characterize benchmark systems and confirm\ncandidate ones with Gaia-Hipparcos accelerations\, double-PSF fitting\, and spectral binary fitting\nprior to the upcoming Gaia DR4. These benchmark systems are also our best atmospheric\nlaboratories to disentangle confounding parameters and their effect on spectroscopy. Together\, these\nstudies bridge separate populations that look alike in their fundamental and atmospheric properties\nbut differ in origin\, leveraging that contrast to trace their stellar or planetary formation histories.
