Scientific paper

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.
