Lallement

1991 PO14. Discovered 1991 Aug. 6 by H. E. Holt at Palomar.

Named in honor of Rosine Lallement (1951), French astrophysicist working at the Service d'Aeronomie in Verrieres-le-Buisson. Lallement was the first to identify the local interstellar cloud, a few parsecs in diameter, which the sun is currently traversing. At a larger scale (100 parsecs), using new stellar distances from Hipparcos, she has studied the boundary of the interstellar local bubble, a region of very low interstellar density and high temperature, and she has discovered a hole in the local bubble, called the local tube, connecting it to the galactic halo.
