« Highlights from Hipparcos »

Michael Perryman

The catalogues resulting from the Hipparcos space astrometry mission were published in 1997. Since then, several thousand papers have been published making use of the data. The Hipparcos data have been applied to a broad range of astronomical research, which can be classified into three major themes: the provision and use of an accurate reference frame, constraints on stellar structure and evolution, and studies of Galactic structure, kinematics and dynamics.
Associated with these major themes, Hipparcos has provided results in topics as diverse as Solar System science, including mass determinations of asteroids, Earth rotation and Chandler Wobble, the internal structure of white dwarfs, the masses of brown dwarfs, the characterisation of exo-planets and their host stars, the height of the Sun above the Galactic mid-plane, the age of the Universe, the stellar initial mass function and star formation rates, and search strategies for extraterrestrial intelligence.

The seminar will review the key topics addressed in the Hipparcos literature over the last 10 years.
