Applications of the infrared flux method to 3 cool AP stars (78 Virginis, 52 Herculis A and CS Virginis) and comparison of their energy distributions to model atmospheres.
Abstract
The infrared flux method proposed by Blackwell and Shallis (1977) is used, along with a comparison of the observed energy distribution to model grids, in order to determine the fundamental parameters of three cool Ap stars: 78 Vir, 52HerA, and CS Vir. The degree to which their energy distributions can be reproduced using currently available model atmospheres is shown.
