A Brief History of the Study of Nearby Young Moving Groups and Their Members

TL;DR

This paper reviews the development of the study of nearby young moving groups (NYMGs), highlighting their importance in understanding stellar evolution, protoplanetary disks, and exoplanets over the past two decades.

Contribution

It provides a historical overview of NYMG research and illustrates how studying these groups advances knowledge of early stellar and planetary development.

Findings

NYMGs are crucial for studying pre-main sequence stars.

Research on NYMGs has advanced understanding of young exoplanets.

The field has grown significantly over the past two decades.

Abstract

Beginning with the enigmatic (and now emblematic) TW Hya, the scutiny of individual stars and star-disk systems has both motivated and benefitted from the identification of nearby young moving groups (NYMGs). I briefly outline the emergence of this relatively new subfield of astronomy over the past two decades, and offer a few examples illustrating how the study of NYMGs and their members enables unique investigations of pre-main sequence stellar evolution, evolved protoplanetary disks, and young exoplanets.
