Title: The Tumultuous Lives of Luminous Stars: Mass Loss, Mass Transfer, and White Dwarf Kicks

Abstract: Red giants and supergiants have large, tenuous envelopes that are gradually lost via winds. These winds are launched from a dense chromosphere supported by shock waves due to stellar pulsations and vigorous convection. The resulting mass loss is stochastic, episodic, and asymmetric, with profound consequences on stellar evolution. For exploding red supergiants, the dense…
