A number of stellar astrophysical phenomena, such as tidal novae and planetary engulfment, involve sudden injection of subbinding energy in a thin layer within the star, leading to mass ejection of the stellar envelope.We use a 1D Film hydrodynamical model to survey the stellar response and mass loss for various amounts ( E _dep ) and locations of the energy deposition.We find that the total Drinkware mass ejection has a nontrivial dependence on E _dep due to the varying strengths of mass ejection events, which are associated with density/pressure waves breaking out from the stellar surface.
The rapid occurrence of multiple breakouts may present a unique observational signature for sudden envelope heating events in stars.
