Évry Léon Schatzman (Neuilly-sur-Seine, 16 de setembro de 192025 de abril de 2010)[1] foi um astrofísico francês.[2][3]

Vida

Evry Schatzman foi encarregado dos Cursos Peccot de matemática no Collège de France em 1950-1951.[4]

De 1970 a 2001, Evry Schatzman foi presidente da União Racionalista.

Anãs brancas e a teoria do aquecimento por ondas

Schatzman trabalhou com anãs brancas durante os anos 1940. Ele percebeu que as atmosferas das anãs brancas deveriam ser estratificadas gravitacionalmente, com hidrogênio no topo e elementos mais pesados ​​abaixo,[5][6], §5–6 e explicou a ionização por pressão em atmosferas de anãs brancas. Ele foi um dos proponentes da teoria do aquecimento por ondas da coroa solar.[7][8] Schatzman propôs o mecanismo de frenagem magnética, pelo qual fluxos de saída diminuem a rotação estelar.[9]

Schatzman escreveu o livro de astrofísica Astrophysique Générale e contribuiu muito para a popularidade da astrofísica na França. Ele recebeu o Prix ​​Jules Janssen da Société astronomique de France (Sociedade Astronômica Francesa) em 1973, o Prêmio Holweck em 1985 e a Medalha de Ouro do CNRS em 1983. Tornou-se membro da Academia Francesa de Ciências em 1985.[10][11]

O CNRS reconheceu Schatzman como "o pai da astrofísica francesa moderna".[1]
