Large Scale Searches for Brown Dwarfs and Free-Floating Planets
arXiv:1805.05661 · doi:10.1007/978-3-319-55333-7_118
Abstract
Searches of large scale surveys have resulted in the discovery of over 1000 brown dwarfs in the Solar neighbourhood. In this chapter we review the progress in finding brown dwarfs in large datasets, highlighting the key science goals, and summarising the surveys that have contributed most significantly to the current sample.
