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.
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.
