An Incipient Debris Disk in the Chamaeleon I Cloud
C. C. Espaillat, Á. Ribas, M. K. McClure +5
The point at which a protoplanetary disk becomes a debris disk is difficult to identify. To better understand this, here we study the 40~AU separation binary T~54 in the Cham…
Submillimeter H2O masers in water-fountain nebulae
D. Tafoya, R. Franco-Hernández, W. H. T. Vlemmings +2
We report the first detection of submillimeter water maser emission toward water-fountain nebulae, which are post-AGB stars that exhibit high-velocity water masers. Using APEX we f…
Magnetic Fields in Evolved Stars: Imaging the Polarized Emission of High-Frequency SiO Masers
W. H. T. Vlemmings, E. M. L. Humphreys, R. Franco-Hernández
We present Submillimeter Array observations of high frequency SiO masers around the supergiant VX Sgr and the semi-regular variable star W Hya. The J=5-4, v=1 28SiO and v=0 29SiO m…
Time Variation in the Radio Flux Density from the Bipolar Ultracompact H II Region NGC 7538 IRS1
Ramiro Franco-Hernández, Luis F. Rodrí guez
We present high angular resolution (-) VLA observations at 2 and 6 cm made in 1983, 1986, and 1995 toward the ultracompact bipolar H II region NGC 7…
