Bispectrum speckle interferometry of the massive protostellar outflow source IRAS 23151+5912
G. Weigelt, H. Beuther, K. -H. Hofmann +5
We present bispectrum speckle interferometry of the massive protostellar object IRAS 23151+5912 in the near-infrared K' band. The reconstructed image shows the diffuse nebulosity n…
The vicinity of the galactic supergiant B[e] star CPD -57 2874 from near- and mid-IR long baseline spectro-interferometry with the VLTI (AMBER and MIDI)
A. Domiciano de Souza, T. Driebe, O. Chesneau +8
We present the first spectro-interferometric observations of the circumstellar envelope (CSE) of a B[e] supergiant (CPD -57 2874), performed with the Very Large Telescope Interfero…
Disk and wind interaction in the young stellar object MWC 297 spatially resolved with VLTI/AMBER
F. Malbet, M. Benisty, W. J. De Wit +15
The young stellar object MWC 297 has been observed with the VLT interferometer equipped with the AMBER instrument. MWC 297 has been spatially resolved in the continuum with a visib…
High angular resolution N-band observation of the silicate carbon star IRAS08002-3803 with the VLTI/MIDI instrument
Keiichi Ohnaka, T. Driebe, K. -H. Hofmann +10
We present the results of N-band spectro-interferometric observations of the silicate carbon star IRAS08002-3803 with the MID-infrared Interferometric instrument (MIDI) at the Very…
AMBER : a near infrared focal instrument for the VLTI
Romain G. Petrov, Fabien Malbet, Andrea Richichi +3
AMBER is the General User near-infrared focal instrument of the Very Large Telescope interferometer. Its specifications are based on three key programs on Young Stellar Objects, Ac…
Disentangling the wind and the disk in the close surrounding of the young stellar object MWC297 with AMBER/VLTI
Fabien Malbet, M. Benisty, W. J. De Wit +13
The young stellar object MWC297 is a B1.5Ve star exhibiting strong hydrogen emission lines. This object has been observed by the AMBER/VLTI instrument in 2-telescope mode in a sub-…
A quasi-time-dependent radiative transfer model of OH104.9+2.4
D. Riechers, Y. Balega, T. Driebe +4
We investigate the pulsation-phase dependent properties of the circumstellar dust shell (CDS) of the OH/IR star OH104.9+2.4 based on radiative transfer modeling (RTM) using the cod…
