High Time Resolution Spectroscopic Observations of Stellar Shock Waves
Abstract
An absorption line-splitting phenomenon has been shown to occur at about maximum light in the semi-regular pulsations of the R Coronae Borealis star, RY Sgr (Lawson 1986). This has been interpreted as a shock wave propagating through the photospheric layers (Lawson and Cottrell, 1986). The authors present spectroscopic observations of this star, taken to coincide with this line-splitting event.
