South Korean Team Discovers Warm Ring Around Protostar

Summary

Story summary

A South Korean research team found a warm ring around the protostar L1521F in Taurus, about 93 billion miles across.
The ring results from magnetic stress and changes the gas environment for star formation.
Using the Atacama Large Millimeter/submillimeter Array (ALMA), researchers confirmed a magnetohydrodynamic disk wind.
The wind ejects matter and helps regulate angular momentum.
Future work will study similar structures around other protostars to assess commonality.
