- 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.
- Seattle Neighborhoods: University District — Thumbnail History (historylink.org)
Seattle’s University District, home of the University of Washington since 1895, is located in the northeast section of the city, north of the Portage Bay part of Lake Union. Its main spurs to development were the developer James Moore (1861-1929), the 1895 move of the Territorial University from downtown to what was then called Brooklyn, and the Alaska-Yukon-Pacific Exposition on the University of Washington campus in 1909. In the late twentieth century, the main challenges to this “city within a city” have been the development of nearby malls. It is a neighborhood of restaurants, cafes, a renowned street fair, a farmer’s market, and a few venerable institutions such as the University Book Store, University Inn, and the Meany Hotel.
