There are sinusoidal light variations with A(V) = 0.15m and elements Min = 2443767.475 + 0.4392d*E in the descending branch of the light curve after JD2443765 [F.Campolonghi, R.Gilmozzi, U.Guidoni, R.Messi, G.Natali, J.Wells, AsAp 85, L4, 1980.]. Infrared light curves (1.6 - 10 mkm) have a secondary maximum (JD2443815) due to the formation of the dust envelope. At 10 mkm this secondary maximum is brighter than the primary one [R.D.Gehrz, J.A.Hackwell, G.L. Grasdalen, E.P.Ney, G.Neugerauer, K.Sellgren, ApJ 239, N2, 570, 1980.]. |
