On the evolutionary stage of the unclassified B[e] star CD-42o11721
Marcelo Borges Fernandes, Michaela Kraus, Silvia Lorenz Martins +1
The star CD-42o11721 is a curious B[e] star sometimes pointed as an evolved B[e] supergiant and sometimes as a young HAeBe star, due to very uncertain or even unknown stellar param…
Hydrogen neutral outflowing disks of B[e] supergiants
M. Kraus, M. Borges Fernandes, F. X. de Araujo
The [O I] line emission of the LMC B[e] supergiant R126 is modeled with an outflowing disk scenario. We find that hydrogen in the disk must be ionized by less than 0.1%, meaning th…
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 (…
