Werner Landgraf

Werner Landgraf ( born July 29, 1959 in Mainz ) is a German astrophysicist.

Life

Landgraf studied from 1977 physics at the University of Siegen and operational first astronomical projects. After the bachelor's degree, he moved in 1979 to the University of Göttingen and chose the field of study astrophysics. His thesis The calculation of atmospheric models and line profiles for the analysis of stellar spectra he graduated in 1983; then he worked until 1988 Nichtgravitative on his dissertation forces when Halley 's Comet. ( Supervisor: Hans -Heinrich Voigt )

In 1986, Landgraf was appointed lecturer at the University of Siegen. In addition to the main lecture on astronomy and astrophysics while predominantly solar system objects were treated and their movement, relativity and cosmology.

Work

Landgraf's work mainly concern the verification and determination of constants of astronomical reference system, the masses of the planets, nichtgravitativer forces and the verification of the law of gravitation in the solar system. He developed and improved methods for identifying and calculating the orbits of various objects in the solar system. He studied in this work with numerous small planets with emphasis on the near-Earth asteroids, comets selected, their long term dynamics and the observation of small planets and comets. He also developed a method of eliminating some systematic positioning errors brighter comets, which allowed a more accurate prediction of Halley's comet for the probe projects by 1986. A recalculation of the path of Halley's comet to 2317 BC confirmed that the Greeks had already spotted this 466 BC.

He discovered at the European Southern Observatory various minor planets, such as ( 3683 ) Baumann ( 4378 ) Voigt, named after Hans -Heinrich Voigt ( 9938 ) Kretlow and those with the lowest elongation at the discovery ( 4349 ) Tibúrcio.

In the years after Landgraf dealt with cosmological considerations about the logical, geometrical and physical consequences of a successive action and effect as a concretization of events with a causality of irrevocable Old to genuinely new way such that Miscellaneous nowhere mutually contradictory or confused displayed affects what, makes its appearance as a linearly independent dimensions and they realized natural forces including their finite range, order and relationships to each other, and other basic properties of our world in the aftermath of the earliest primordial events that are associable with them concretely.

Honors

1987, the Small Planet ( 3132 ) Landgraf was named after him.
