## TL;DR

High-resolution infrared spectroscopic surveys of ultracool dwarf stars and brown dwarfs are essential for understanding their origins, compositions, and the Milky Way's evolution, revealing detailed physical and chemical properties.

## Contribution

This white paper advocates for high-resolution infrared spectroscopic surveys targeting ultracool dwarfs and brown dwarfs to advance understanding of their properties and galactic history.

## Key findings

- Revealed origins and compositions of ultracool dwarfs
- Informed star formation and chemical evolution models
- Enhanced understanding of multiplicity and physical properties

## Abstract

High resolution spectroscopy of the lowest-mass stars and brown dwarfs reveals their origins, multiplicity, compositions and physical properties, with implications for the star formation and chemical evolution history of the Milky Way. We motivate the need for high-resolution, infrared spectroscopic surveys to reach these faint sources.
