- A Hipparcos Census of the Nearby OB Associations (iopscience.iop.org)
A comprehensive census of the stellar content of the OB associations within 1 kpc from the Sun is presented, based on Hipparcos positions, proper motions, and parallaxes. It is a key part of a long-term project to study the formation, structure, and evolution of nearby young stellar groups and related star-forming regions. OB associations are unbound “moving groups,” which can be detected kinematically because of their small internal velocity dispersion. The nearby associations have a large extent on the sky, which traditionally has limited astrometric membership determination to bright stars (V ≲ 6 mag), with spectral types earlier than ∼B5. The Hipparcos measurements allow a major improvement in this situation.

RoboCop (1987) is a Sci Fi/Cyberpunk film set Twenty Minutes Into the Future in a Crapsack World version of Detroit, where the police force has been privatized and handed over to Omni Consumer Products (OCP). Officer Alex Murphy (Peter Weller) is trailing a vicious criminal gang led by Clarence Boddicker when he is separated from his partner, Anne Lewis. Boddicker (Kurtwood Smith) and his cronies overwhelm Murphy, then take delight in unloading their shotguns into him.
