Binary and Multiple Star Formation - How Do Stars Get Their Spin?

Explore groundbreaking research on protostellar multiplicity and star formation mechanisms in this physics lecture from Heidelberg University. Delve into the bimodal separation distribution in binary star systems and discover how core fragmentation successfully reproduces observational data, particularly for binary systems with separations down to 20AU. Learn about the complexities of interpreting binary simulation observations and gain insights into the relationship between stellar spin and binary formation. Examine new findings that suggest circumstellar disc fragmentation events can accelerate the primary star's rotation, contributing to our understanding of fast-rotating stars' origins.
