We report regular and symmetric structure around dust-enshrouded Be star MWC 922 obtained with infrared imaging. Biconical lobes that appear nearly square in aspect, forming this “Red Square” nebula, are crossed by a series of rungs that terminate in bright knots or “vortices,” and an equatorial dark band crossing the core delimits twin hyperbolic arcs. The intricate yet cleanly constructed forms that comprise the skeleton of the object argue for minimal perturbation from global turbulent or… 

A highly collimated jet from the Red Square nebula MWC 922

Deep, narrow-band \Ha\ and 6584 \AA\ [\Nii ] CCD images of the peculiar, infrared excess B[e] star MWC~922 reveal a collimated, bipolar jet orthogonal to the previously detected extended nebula. The

A rotating fast bipolar wind and disk system around the B[e]-type star MWC 922.

TLDR
The physical conditions and kinematics in the inner layers of MWC 922 are described with unparalleled detail, which has revealed itself as an ideal laboratory for studying the interplay of disk rotation and jet-launching.

AN INFRARED DIFFUSE CIRCUMSTELLAR BAND? THE UNUSUAL 1.5272 μm DIB IN THE RED SQUARE NEBULA

The molecular carriers of the ubiquitous absorption features called the diffuse interstellar bands (DIBs) have eluded identification for many decades, in part because of the enormous parameter space

MORPHOLOGY OF THE RED RECTANGLE PROTO-PLANETARY NEBULA

The morphology of the Red Rectangle (RR) exhibits several singular attributes. Most prominent are a series of linear features perpendicular to the symmetry axis which appear as “ladder rungs” across

Medium-resolution échelle spectroscopy of the Red Square Nebula, MWC 922

Context. Medium-resolution echelle spectra of the Red Square Nebula surrounding the star MWC 922 are presented. The spectra have been obtained in 2010 and 2012 using the X-shooter spectrograph

Search for DIBs in Emission: MWC 922 - The Red Square Nebula

Abstract This work focusses on MWC 922, the central object in the Red Square Nebula. We obtained low and medium resolution spectra of both, the central object and the surrounding nebula, using the

A 3D dynamical model of the colliding winds in binary systems

We present a three-dimensional (3D) dynamical model of the orbital-induced curvature of the wind–wind collision region in binary star systems. Momentum balance equations are used to determine the

Abstract The total number of true, likely and possible planetary nebulae (PN) now known in the Milky Way is nearly 3000, double the number known a decade ago. The new discoveries are a legacy of the

A mid-infrared imaging catalogue of post-asymptotic giant branch stars

Post-asymptotic giant branch (post-AGB) stars are key objects for the study of the dramatic morphological changes of low- to intermediate-mass stars on their evolution from the AGB towards the

The $Z$-Pinch Morphology of Supernova 1987A and Electric Stars

Supernova 1987A (SN 1987A) is the closest supernova event since the invention of the telescope. It was first seen in February 1987 in the nearby Large Magellanic Cloud, which is a dwarf companion
