Near-Infrared echelle spectroscopy of Proto-Planetary Nebulae: probing the fast wind in H2
C. J. Davis, M. D. Smith, T. M. Gledhill +1
Echelle spectroscopy of H2, [FeII] and Br-gamma line emission from a very young planetary nebula, IRAS 21282+5050, and from four proto-planetary nebulae, IRAS 19343+2926 (M 1-92),…
Mid-infrared imaging and modelling of the dust shell around post-AGB star HD 187885 (IRAS 19500-1709)
K. L. Clube, T. M. Gledhill
We present 10 and 20 micron images of IRAS 19500-1709 taken with the mid-infrared camera, OSCIR, mounted on the Gemini North Telescope. An extended circumstellar envelope is detect…
HeI 1.083 micron emission and absorption in DG Tau: line excitation in jet, hot wind, and accretion flow
M. Takami, A. Chrysostomou, J. Bailey +3
We present long-slit spectroscopy and spectro-astrometry of HeI 1.083 micron emission in the T Tauri star, DG Tau. We identify three components in the HeI feature: (1) a blueshifte…
Scattered light models of the dust shell around HD 179821
T. M. Gledhill, M. Takami
The dust shell around the evolved star HD 179821 has been detected in scattered light in near-IR imaging polarimetry observations. Here, we subtract the contribution of the unpolar…
Circumstellar structure of RU Lupi down to au scales
M. Takami, J. Bailey, T. M. Gledhill +2
We have used the technique of spectro-astrometry to study the milli-arcsecond scale structure of the emission lines in the T Tauri star RU Lupi. The wings of the H-alpha emission a…
Axisymmetry in proto-planetary nebulae: using imaging polarimetry to investigate envelope structure
T. M. Gledhill, A. Chrysostomou, J. H. Hough +1
We use ground-based imaging polarimetry to detect and image the dusty circumstellar envelopes of a sample of proto-planetary nebulae (PPNe) at near-infrared wavelengths. We detect…
