Gomez's Hamburger (IRAS 18059-3211): A pre main-sequence A-type star
V. Bujarrabal, K. Young, D. Fong
We study the nature of Gomez's Hamburger (IRAS 18059-3211), a nebula that has been proposed to be a post-AGB object. Such a classification is not confirmed; instead, we argue that…
Submillimeter Array Observation of the Proto-Planetary Nebula CRL 618 in the CO J=6-5 Line
Jun-ichi Nakashima, David Fong, Tatsuhiko Hasegawa +6
We report on the results of a Submillimeter Array interferometric observation of the proto-planetary nebula CRL 618 in the 12CO J=6-5 line. With the new capability of SMA enabling…
The distribution of H13CN in the circumstellar envelope around IRC+10216
F. L. Schoeier, D. Fong, J. H. Bieging +3
H13CN J=8-7 sub-millimetre line emission produced in the circumstellar envelope around the extreme carbon star IRC+10216 has been imaged at sub-arcsecond angular resolution using t…
Non-equilibrium chemistry and dust formation in AGB stars as probed by SiO line emission
F. L. Schoeier, H. Olofsson, T. Wong +3
We have performed high spatial resolution observations of SiO line emission for a sample of 11 AGB stars using the ATCA, VLA and SMA interferometers. Detailed radiative transfer mo…
The distribution of SiO in the circumstellar envelope around IRC+10216
F. L. Schoeier, D. Fong, H. Olofsson +2
New interferometric observations of SiO J=5-4 circumstellar line emission around the carbon star IRC+10216, using the Submillimeter Array, are presented. Complemented by multi-tran…
The Molecular and Dust Envelope of HD 56126
M. Meixner, A. Zalucha, T. Ueta +2
We present millimeter interferometry images of the CO J=1-0 line emission arising in the circumstellar envelope of HD 56126 (a.k.a. IRAS 07134+1005), which is one of the best studi…
