Description
  • We present a study of the optical spectrum of the fascinating B[e] star Hen2-90 based on new high-resolution observations taken with FEROS at the ESO 1.52m telescope in La Silla (Chile). Our modeling of the forbidden emission lines results in strong evidence for Hen2-90 being a compact planetary nebulae that has undergone a superwind phase of high, non-spherical mass loss, most probably triggered by a central star that was rotating with about 80% of the critical velocity.

  • Předkládáme studii optického spektra fascinující B[e] hvězdy Hen2-90 založenou na nových vysokodisperzních pozorováních získaných spektrografem FEROS na ESO 1.52m dalekohledu v La Silla (Chile). Naše modelování zakázaných emisních čar vede k závěru, že Hen2-90 je kompaktní planetární mlhovina, která prodělala supervětrnou fázi velké nesférické ztráty hmoty, nejpravděpodobněji způsobené centrální hvězdou rotující s rychlostí kolem 80% kritické rychlosti.
