Resolving the dusty circumstellar environment of the A[e] supergiant HD 62623 with the VLTI/MIDI
A. Meilland, S. Kanaan, M. Borges Fernandes +4
B[e] stars are hot stars surrounded by circumstellar gas and dust responsible for the presence of emission lines and IR-excess in their spectra. How dust can be formed in this high…
The galactic unclassified B[e] star HD 50138. I. A possible new shell phase
Marcelo Borges Fernandes, Michaela Kraus, Olivier Chesneau +4
The observed spectral variation of HD 50138 has led different authors to classify it in a very wide range of spectral types and luminosity classes (from B5 to A0 and III to Ia) and…
Halpha spectropolarimetry of the B[e] supergiant GG Carinae
A. Pereyra, F. X. de Araujo, A. M. Magalhaes +2
Aims. We study the geometry of the circumstellar environment of the B[e] supergiant star GG Car. Methods. We present observations acquired using the IAGPOL imaging polarimeter in c…
B[e] stars at the highest angular resolution: the case of HD87643
Florentin Millour, Olivier Chesneau, Marcelo Borges Fernandes +1
New results on the B[e] star HD87643 are presented here. They were obtained with a wide range of different instruments, from wide-field imaging with the WFI camera, high resolution…
Catching the Binaries Amongst B[e] Stars
Michaela Kraus, Marcelo Borges Fernandes, Olivier Chesneau
It is surprising to find dust around B type stars, as in the case of B[e] stars. These stars exhibit a dense, dusty environment witnessed by their infrared-excess and many emission…
