AMBER/VLTI observations of the B[e] star MWC 300
Y. Wang, G. Weigelt, A. Kreplin +8
Aims. We study the enigmatic B[e] star MWC 300 to investigate its disk and binary with milli-arcsecond-scale angular resolution. Methods. We observed MWC 300 with the VLTI/AMBER in…
AMBER and CRIRES observations of the binary sgB[e] star HD 327083: evidence of a gaseous disc traced by CO bandhead emission
H. E. Wheelwright, W. J. de Wit, G. Weigelt +2
HD 327083 is a sgB[e] star that forms a binary system with an orbital semi-major axis of ~1.7 AU. Our previous observations using the VLTI and AMBER in the medium resolution K-band…
Parsec-scale dust emission from the polar region in the type 2 nucleus of NGC 424
Sebastian F. Hoenig, Makoto Kishimoto, Robert Antonucci +4
Advancements in infrared IR open up the possibility to spatially resolve AGN on the parsec-scale level and study the circumnuclear dust distribution, commonly referred to as the "d…
Probing the innermost dusty structure in AGN with mid-IR and near-IR interferometers
Makoto Kishimoto, Sebastian F. Hoenig, Robert Antonucci +5
With mid-IR and near-IR long-baseline interferometers, we are now mapping the radial distribution of the dusty accreting material in AGNs at sub-pc scales. We currently focus on Ty…
The complexity of parsec-scaled dusty tori in AGN
K. R. W. Tristram, M. Schartmann, L. Burtscher +5
Warm gas and dust surround the innermost regions of active galactic nuclei (AGN). They provide the material for accretion onto the super-massive black hole and they are held respon…
On the influence of the companion star in Eta Carinae: 2D radiative transfer modeling of the ultraviolet and optical spectra
Jose H. Groh, D. John Hillier, Thomas I. Madura +1
We present 2D radiative transfer modeling of the Eta Carinae binary system accounting for the presence of a wind-wind collision (WWC) cavity carved in the optically-thick wind of t…
