dc.description.abstract	We discuss our recent observations of the interesting but enigmatic nova-like variable V4332 Sgr. The object shows a remarkably rich near-infrared and optical spectrum with several unusual spectral features generally not seen in classical novae. Our results support the emerging consensus that V4332 Sgr, and its possible analog V838 Mon, constitute a new class of eruptive variables. Our results indicate that a cold circumstellar disc containing gas, dust and water ice surrounds the object. Though the cause of the outburst in these objects is not completely understood, we propose a plausible planetary-capture scenario to explain the eruption of V4332 Sgr	en
