Everything about Julio Ngel Fern Ndez totally explained
Dr. Julio Ángel Fernández Alves (born
Montevideo,
5 April 1946) is a
Uruguayan astronomer and member of the department of astronomy at the
Universidad de la República in
Montevideo. He is also a member of PEDECIBA, (the program for development of basic sciences in Uruguay).
In 1980, in his paper
On the existence of a comet belt beyond Neptune, Fernández proposed that
periodic comets arrived too frequently into the inner Solar System to be accounted for solely by having arrived from the Oort cloud, and that a trans-Neptunian belt of comets at around 50 AU would be required to explain them. Subsequent computer models by Martin Duncan, Tom Quinn and
Scott Tremaine in Canada supported the view, and led eventually to the discovery of the
Kuiper belt. Many astronomers, including
David Jewitt, who discovered the belt, believe that Fernandez deserves more credit than anyone else, including
Gerard Kuiper, for predicting its existence. He has subsequently published many papers on the
trans-Neptunian population. The IAU's final definition incorporated much of Fernández's proposal.
