Unraveling the Dusty Environment around RT Vir

Sargent, B.; Speck, Angela K.; Preston, Michael D. +1 more

Infrared (IR) studies of asymptotic giant branch (AGB) stars are critical to our understanding of the formation of cosmic dust. In this investigation, we explore the mid- to far-IR emission of the oxygen-rich AGB star RT Virginis. This optically thin dusty environment has unusual spectral features when compared to other stars in its class. To expl…
