Study Challenges Beliefs on Winds from Red Giant Star

12/30/2025

Summary

Story summary

Chalmers University of Technology's study finds starlight may not drive winds from red giant R Doradus, 180 light-years away.
The dust grains around R Doradus are too small to be pushed by starlight, challenging beliefs about life-essential elements.
The study uses advanced observations and simulations to show that other processes, such as giant convective bubbles or pulsations, may launch winds.
The findings are published in Astronomy & Astrophysics.
