OH 0739-14 an old star blowing bubbles [1987IAUS..122..247R]
Two large bipolar bubbles emanating from the OH/IR star OH0739-14 have been discovered...
The OH/IR star OH0739-14, also known at OH231.8+4.2, has a faint optical counterpart, a small elongated nebula, which reflects the light of an embedded M9 giant or supergiant...
Deep CCD images of OH0739-14 through various interference filters have been carried out at the Danish 1.5m telescope at ESO, La Silla. Fig. 1 shows an H-alpha image, on which three basic features of the object can be identified. Firstly, the optical reflection nebulosity is seen as two bright, rather narrow lanes. Secondly, an obscuring disk cuts across these two lanes, and thirdly, two large shock-excited bubbles surround the reflection lanes...
The outflow is probably generated by the wind from a hot accretion-disk surrounding a companion white dwarf. The companion accretes matter from the mass-losing red giant, which is at the very end of AGB evolution. We are most likely here witnessing the rapid evolution immediately preceding the formation of a bipolar planetary nebula.
The dynamics of the Calabash Nebula [1989A&A...211..409I]
".. in the remarkable nebula OH 231.8+4.2 which, because of its peculiar shape (Fig. 1; Reipurth, 1987) we propose to call the 'Calabash Nebula'. "
High-resolution, near-IR spectroscopy and imaging of the Egg and Rotten Egg nebulae (AFGL 2688 and OH 231.8+4.2) [1999IAUS..191..431K]
The evolved bipolar nebula OH 231.8+4.2 is host to a Mira, QX Pup, at its core. We used the DLIRIM system at Kitt Peak to obtain the first direct imags of QX Pup in the near-infrared... In subarcsecond resolution the star lies midway between the lobes of the OH 231.8+4.2 reflection nebula... the central Mira appears remarkably "normal" given its position at the heart of such an unusual object.
Rotten Egg nebula: The magnetic field of a binary evolved star [2012A&A...540A..42L]
Located at a distance of about 1540 pc, the bipolar nebula OH 231.8+4.2 contains a binary system in its core, where a Main Sequence type A star accompanies an evolved star - the Mira variable QX Pup.
