Giorgio Abetti

Giorgio Abetti ( born October 5, 1882 in Padua (Italy ); † August 24, 1982 in Florence ) was an Italian astronomer.

Giorgio Abetti was the son of the astronomer Antonio Abetti, the former director of the Arcetri Observatory in Florence. He studied in Rome and Padua and received his PhD in 1904 in Padua. Abetti first worked as an assistant in Heidelberg, from 1908 in Chicago (Mt. Wilson Observatory), 1909 in Naples, and from 1910 at the Observatory of the Collegio Romano in Rome.

In 1921 he took over after his father, the Office of the Director of Arcetri, which he held until 1953. Between 1921 and 1957 he was a professor at the University of Florence. He led two expeditions to observe the solar eclipse of 1936 in Siberia, and in 1952 in Sudan.

Giorgio Abetti explored in particular the physics of the sun and published important work on the structure of the chromosphere and the flow of gas masses in the interior of sunspots.

In 1948 and 1949 he was a visiting professor in Cairo (Egypt) and 1950 in the United States.

Giorgio Abetti was Vice President of the International Astronomical Union ( IAU). For his work he received numerous honors, including the 1937 Jules Janssen Award.

In honor of father and son Abetti two lunar craters and the asteroid ( 2646 ) Abetti were named.
