Investigation of dust properties of the proto-planetary nebula IRAS 18276-1431
K. Murakawa, H. Izumiura, R. D. Oudmaijer +1
We investigate the circumstellar dust properties of the oxygen-rich bipolar proto-planetary nebula IRAS 18276-1431 by means of two-dimensional radiative transfer simulations of the…
Dust shell model of the water fountain source IRAS 16342--3814
K. Murakawa, H. Izumiura
We investigate the circumstellar dust shell of the water fountain source IRAS 16342-3814. We performed two-dimensional radiative transfer modeling of the dust shell, taking into ac…
Evolved star water maser cloud size determined by star size
A. M. S. Richards, S. Etoka, M. D. Gray +5
Cool, evolved stars undergo copious mass loss but the details of how the matter is returned to the ISM are still under debate. We investigated the structure and evolution of the wi…
Detection of high-velocity material from the wind-wind collision zone of Eta Carinae across the 2009.0 periastron passage
Jose H. Groh, Krister E. Nielsen, Augusto Damineli +15
We report near-IR spectroscopic observations of the Eta Carinae massive binary system during 2008-2009 using VLT/CRIRES. We detect a strong, broad absorption wing in He I 10833 ext…
Evidence of grain growth in the disk of the bipolar proto-planetary nebula M 1--92
K. Murakawa, T. Ueta, M. Meixner
We investigate the dust size and dust shell structure of the bipolar proto-planetary nebula M 1--92 by means of radiative transfer modeling. Our models consists of a disk and bipol…
Resolving the asymmetric inner wind region of the yellow hypergiant IRC+10420 with VLTI/AMBER in low and high spectral resolution mode
T. Driebe, J. H. Groh, K. -H. Hofmann +15
We obtained near-infrared long-baseline interferometry of IRC+10420 with the AMBER instrument of ESO's Very Large Telescope Interferometer (VLTI) in low and high spectral resolutio…
