Parallaxes and proper motions of prototypes of astrophysically interesting classes of stars
Hipparcos data are presented for 13 stars belonging to six differentevolutionary types that present various puzzles. There are three FKComae stars, one Wolf-Rayet binary, the 'galloping giant' FG Sagittae,two high-velocity B stars, two runaway T Tauri stars, and fourcataclysmic variables. Most of the numbers are of limited statisticalsignificance, because even the best-known examples of rare classes ofstars are likely to be distant and faint. In most cases, the stars areconfirmed as being more or less what was expected. A few are not. Wepresent these data primarily to call attention to the fact that the118,226 stars in the Hipparcos Catalog include some that are ofindiviual, as well as of statistical, interest.
