Infrared light curves of the central object of NGC 2346 : the shape of the obscuring cloud.
Abstract
Infrared light curves of the central object of NGC 2346 show that the observed flux originates from the central A-type star and a warm circumstellar dust cloud. Two eclipses are seen in the J and H bands instead of the single eclipse previously reported from visual measurements. No light modulation is present at longer wavelengths. A simple model in terms of the passage of an elongated cloud can account for most of the existing observations.
