Circumstellar matter around the RS CVn system II Peg
The RS CVn noneclipsing system II Peg has been observed in the J, H, K, L, and M infrared bands along a complete period. The shape of the light curve shows an unusual size and concentration of the dark spots in one of the hemispheres of the star. Photometric spectral type K3 IV is derived for the unperturbed photosphere and M4 for the dark spots
