First spectro-interferometric survey of Be stars I. Observations and constraints on the disks geometry and kinematics
Anthony Meilland, Florentin Millour, Samer Kanaan +5
Context. Classical Be stars are hot non-supergiant stars surrounded by a gaseous circumstellar disk that is responsible for the observed infrared-excess and emission lines. The phe…
Mapping the radial structure of AGN tori
Makoto Kishimoto, Sebastian F. Hoenig, Robert Antonucci +3
We present mid-IR interferometric observations of 6 type 1 AGNs at multiple baseline lengths of 27--130m, reaching high angular resolutions up to lambda/B~0.02 arcseconds. For two…
The 2011 outburst of the recurrent novaT Pyx. Evidence for a face-on bipolar ejection
Olivier Chesneau, A. Meilland, D. P. K. Banerjee +19
We report on near-IR interferometric observations of the outburst of the recurrent nova T Pyx. We obtained near-IR observations of T Pyx at dates ranging from t=2.37d to t=48.2d af…
The binary Be star δ Sco at high spectral and spatial resolution: Disk geometry and kinematics before the 2011 periastron
Anthony Meilland, O. Delaa, Philippe Stee +17
Classical Be stars are hot non-supergiant stars surrounded by a gaseous circumstellar disk that is responsible for the observed IR-excess and emission lines. The influence of binar…
Imaging the dynamical atmosphere of the red supergiant Betelgeuse in the CO first overtone lines with VLTI/AMBER
K. Ohnaka, G. Weigelt, F. Millour +6
We present the first 1-D aperture synthesis imaging of the red supergiant Betelgeuse in the individual CO first overtone lines with VLTI/AMBER. The reconstructed 1-D projection ima…
The galactic unclassified B[e] star HD 50138. II. Interferometric constraints on the close circumstellar environment
Marcelo Borges Fernandes, Anthony Meilland, Philippe Bendjoya +7
HD 50138 is a southern star that presents the B[e] phenomenon, but its evolutionary stage is still not well known. This object presents spectral variability, which can be explained…
