Abstract
FU Orionis objects (FUors) are young stars that have recently undergone major outbursts, probably powered by enhanced accretion from the circumstellar disc to the star. Parsamian 21 is a unique FUor, as it is thought to be surrounded by an edge-on circumstellar disc, making it an ideal case for studying the geometry and structure of the circumstellar material. In this paper we report on new adaptive optics assisted near-infrared direct and polarimetric measurements of Parsamian 21 taken with the NaCO instrument on the VLT. With the help of these observations, we search for companions and study the innermost part of the circumstellar disc with an unprecedented resolution and contrast.
