Photometry, Stars: Variables: Individual (Ag Peg)

Scientific paper

We have made UBVJHKL broad-band photometry, and H_β and H_δ narrow-band photometry of the symbiotic star AG Pegasi. The β and δ-indices for this object are the strongest among nearly 200 Be stars (which include P Cygni) and standard stars. The UBV photometry of AG Peg is similar to a reddened early type star. Its infrared photometry corresponds very closely to an M3 III star. This confirms the results of several spectroscopic studies which conclude that this nova-like star is a binary, comprising a hot WN6 component and a cool M3 III object embedded in a gas cloud.
