The environment of the fast rotating star Achernar - Thermal infrared interferometry with VLTI/MIDI and SIMECA modeling
Pierre Kervella, Armando Domiciano De Souza, Samer Kanaan +3
Context: As is the case of several other Be stars, Achernar is surrounded by an envelope, recently detected by near-IR interferometry. Aims: We search for the signature of circumst…

delta Cen: a new binary Be star detected by VLTI/AMBER spectro-interferometry
Anthony Meilland, Florentin Millour, Philippe Stee +5
We study the Be star Cen circumstellar disk using long-baseline interferometry which is the only observing technique capable of resolving spatially and spectroscopically object…

The origin of hydrogen line emission for five Herbig Ae/Be stars spatially resolved by VLTI/AMBER spectro-interferometry
S. Kraus, K. -H. Hofmann, M. Benisty +14
To trace the accretion and outflow processes around YSOs, diagnostic spectral lines such as the BrG 2.166 micron line are widely used, although due to a lack of spatial resolution,…
