Explore a 49-minute astronomy lecture examining how stellar winds from Asymptotic Giant Branch (AGB) stars interact with companion objects to create complex outflow patterns. Discover how 3D hydrodynamical PHANTOM models demonstrate the formation of intricate structures like spirals, disks, and clumps when stellar or planetary companions gravitationally interact with AGB winds. Learn how these computational simulations provide insights into interpreting actual ALMA telescope observations and understanding the configurations of binary and triple star systems that generate these fascinating wind patterns. Gain knowledge about the final life stages of low and intermediate-mass stars as they disperse their outer envelopes into interstellar space through stellar winds shaped by companion interactions.
