Abstract:
The positions of the IRAS counterparts to the 420 OH/IR stars in the
Arecibo sky (0°<δ<+38°) are usually accurate to better
than 10". But every star has recently been observed by the Two Micron
All Sky Survey (2MASS, II/246), which provides 0.2" quality
positions, while those with |b|≤4.5° have also been observed by
the Midcourse Space Experiment (MSX, V/114), which provides ∼2"
quality positions. We use the MSX and/or IRAS coordinates to guide us
to 2MASS counterparts for the 134 Arecibo OH/IR stars with images in
the second release of the 2MASS Point Source Catalog. An unexpected
by-product of having the J-H versus H-Ks plot generated from the
2MASS fluxes is the realization that most (∼85%) of the redder OH/IR
stars have detached circumstellar shells. We identify five objects
that probably, by contrast, have "normal" shells, and we confirm the
status of AU Vul as a protoplanetary nebula.
