H{alpha} spectra & V-band photometry of {delta} Sco

We determine our best-fitting models through matching simulated observations to actual H{alpha} spectroscopy and V-band photometric observations.

Our modeling results confirm previous findings that the disk of {delta}Sco was forming early in the century. We also find a period of disk dissipation when the companion is at apastron, as well as a significant growth of the disk between 2009 and 2011, prior to the periastron of 2011. Due to the steady-state nature of the disk after 2011, it is difficult to say whether the variations seen are due to the effect of the close passage of the binary companion.
