2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/8330We 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.5 pages, to appear in proceedings of "Massive Stars in Interacting Binaries", (eds.)
