Strong near-infrared emission in the sub-AU disk of the Herbig Ae star HD163296: evidence for refractory dust? (2009)

Benisty, M., Natta, A., Isella, A., Berger, J-P., Massi, F., LeBouquin, J-B., ...

We present new long-baseline spectro-interferometric observations of the HerbigAe star HD163296 obtained in the H and K bands with the AMBER instrument at VLTI. The observations cover a range of...

The origin of hydrogen line emission for five Herbig Ae/Be stars spatially resolved by VLTI/AMBER spectro-interferometry (2008)

Kraus, S., Benisty, M., Chesneau, O., Isella, A., ...

Context. Accretion and outflow processes are of fundamental importance for our understanding of the formation of stars and planetary systems. To trace these processes, diagnostic spectral lines such...

The origin of hydrogen line emission for five Herbig Ae/Be stars spatially resolved by VLTI/AMBER spectro-interferometry (2008)

Kraus, S., Benisty, M., Chesneau, O., Isella, A., ...

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, the origin of the...

Gas and dust in the inner disk of the Herbig Ae star MWC 758 (2008)

Isella, A., Tatulli, E., Natta, A., Testi, L.

We investigate the origin of the near-infrared emission of the Herbig Ae star MWC 758 on sub-astronomical unit (AU) scales using spectrally dispersed low resolution (R = 35) AMBER/VLTI...

Millimeter imaging of HD 163296: probing the disk structure and kinematics (2007)

Isella, A., Testi, L., Natta, A., Neri, R., Wilner, D., Qi, C.

We present new multi-wavelength millimeter interferometric observations of the Herbig Ae star HD 163296 obtained with the IRAM/PBI, SMA and VLA arrays both in continuum and in the 12CO, 13CO and C18O...

Constraining the wind launching region in Herbig Ae stars: AMBER/VLTI spectroscopy of HD104237 (2006)

Tatulli, E., Isella, A., Natta, A., Testi, L., Marconi, A., Consortium, The AMBER

We investigate the origin of the $\mathrm{Br}\gamma$ emission of the Herbig Ae star HD104237 on Astronomical Unit (AU) scales. Using AMBER/VLTI at a spectral resolution R=1500 spatially resolve the...

Disk and wind interaction in the young stellar object MWC 297 spatially resolved with VLTI/AMBER (2005)
