The Enigmatic B[e] Star Hen 2-90 - an Interacting Binary?
Abstract
We present the enigmatic galactic unclassified B[e] star Hen 2-90. Its optical spectrum is discussed and analysed in terms of the forbidden emission lines coming from a non-spherical wind. The evolutionary phase of Hen 2-90 is discussed. We raise the question whether an interacting binary nature seems to be a possible solution to account for all observed characteristics.
