Estimating Be Star Disk Radii using Hα Emission Equivalent Widths
Estimating Be Star Disk Radii using Hα Emission Equivalent Widths
We present numerical models of the circumstellar disks of Be stars, and we describe the resulting synthetic Hα emission lines and maps of the wavelength-integrated emission flux projected onto the sky. We demonstrate that there are monotonic relationships between the emission-line equivalent width and the ratio of the angular half-width …
