The compact planetary nebula B[e] star Hen 2-90
Michaela Kraus, Marcelo Borges Fernandes, Francisco X. de Araujo +1
We present a study of the optical spectrum of the fascinating B[e] star Hen 2-90 based on new high-resolution observations taken with FEROS at the ESO 1.52m telescope in La Silla (…
The optical and IR properties of southern galactic unclB[e] stars: The case of CD-42 11721
Marcelo Borges Fernandes, Silvia Lorenz Martins, Michaela Kraus +1
(abridged) In this work we present the results of an optical and IR study for the curious B[e] star CD-42 11721. This object has a doubtful evolutionary stage, being either a pre-m…
Ionization structure in the disks and winds of B[e] stars
Michaela Kraus, Henny J. G. L. M. Lamers
We investigate the ionization structure in the non-spherical winds and disks of B[e] stars. Especially the luminous B[e] supergiants seem to have outflowing disks which are neutral…
The enigmatic B[e]-star Henize 2-90: The non-spherical mass loss history from an analysis of forbidden lines
Michaela Kraus, Marcelo Borges Fernandes, Francisco X. de Araujo +1
(abridged) We study the optical spectrum of the exciting B[e] star Hen 2-90 based on new high-resolution observations that cover the innermost 2". Our investigation is splitted in…
