We present HST and ground-based images of the bipolar proto-planetary nebula M1-92. Trammell et al. (1993) studied M1-92 using spectropolarimetry and concluded that the continuum emission is reflected from the inner regions of the object, the forbidden lines are formed locally in the bipolar ...
We present high spatial resolution observations of the CO emission at 2.6mm in the protoplanetary nebula M1-92 (Minkowski’s Footprint), obtained with the Plateau de Bure interferometer. The total mass corresponding to the CO measured intensity is estima
We present HST imaging of continuum (5500 Angstroms) and atomic line (Hα , [OI] 6300 Angstroms, [SII] 6717 and 6731 Angstroms, and [OIII] 5007 Angstroms) emissions in the protoplanetary nebula M 1-92. Ground based imaging of 2$() μm continuum and H_2 ro-vibrational (S(1) v=3D...
VLA observations of the 1667 and 1612 MHz OH brightness distribution in the bipolar nebula M1-92 are presented. The OH emission originates in the circumstellar gas disk whose axis coincides with that of the bipolar lobes. No OH emission is found in the lobes themselves. A simple axisymmetric...
We present high-resolution (1".0) maps of ~13CO J=2-1 in the proto-planetary nebula M1-92, Mink- owski's Footprint, obtained with the Institut de Radioastronomie Millimetrique(IRAM) interferometer at Plateau de Bure. We confirm the main components found in our previous works: a ...
These results indicate that M1-92's slowly expanding equatorial torus exhibits an outer radial cutoff in its density, which implicates the influence of a binary companion during the formation of the nebula.doi:10.3390/galaxies12040044Raghvendra Sahai...

We performed sub-arcsecond resolution observations of the J =2–1 rotational line of 13 CO in M1–92 with the new extended configurations of the IRAM Plateau de Bure interferometer, for studying the morphology and velocity field of the molecular gas better in the nebula, particularly in its ...
We present high spatial resolution observations of the CO emission at 2.6mm in the protoplanetary nebula M1-92 (Minkowski's Footprint), obtained with the Plateau de Bure interferometer. The total mass corresponding to the CO measured intensity is estimated to be large, of about 0.1–0.2 solar ...
The bipolar nebula Ml-92 (Herbig, 1975) consists of a bright and a faint reflection lobe illuminated by a central stellar light source which is embedded in a dense equatorial dust disk. Ml-92 is considered to be a proto-planetary nebula (Eiroa and Hodapp, 1989)....
