Biography
Adela Emilia Ringuelet (27 March 1930 – 26 April 2023) was an Argentine astrophysicist and astronomer known for her work in stellar spectroscopy in Argentina. Born in La Plata, Argentina, she studied astronomy at the Escuela Superior de Astronomía y Geofísica, under the National University of La Plata, alongside Nora Schreiber and Elsa Guttierez. Her education set the stage for a long, successful scientific career, making her one of the leading figures in Argentine astronomy.
In 1958, Ringuelet began her career at the Félix Aguilar Observatory, an institution she was closely linked to throughout her profession. Her research mainly focused on stellar spectroscopy, which involves analyzing the light from stars to understand their composition, temperature, velocity, and other physical characteristics. Throughout her career, she published over 100 papers in this field, making significant contributions to the global understanding of stellar physics.
Ringuelet was married to Jorge Sahade (1915–2012), a prominent Argentine astrophysicist who led both the La Plata and Córdoba Observatories and served as president of the International Astronomical Union (IAU). They collaborated professionally, co-authoring papers on stellar spectroscopy and forming a notable partnership in Argentine astronomical history. Her connection with Sahade brought her into the upper echelons of international astronomy during the latter half of the twentieth century.
Besides her research, Ringuelet co-founded the Argentine Astronomical Association (Asociación Argentina de Astronomía), which united professional astronomers across the country and helped promote astronomical research in Argentina. She was an active member of the International Astronomical Union and took part in several of its commissions over the years. By 2017, she was part of IAU's Division G, focused on Stars and Stellar Physics, showing her ongoing involvement with the international scientific community even in her later years.
In honor of her contributions to astronomy, the main-belt asteroid 5793 Ringuelet, discovered by the Félix Aguilar Observatory staff at El Leoncito in 1975, was named after her. This naming was officially published on 26 September 2007 in the Minor Planet Circular (M.P.C. 60727). Ringuelet passed away on 26 April 2023, in La Plata, Argentina, at the age of 93, leaving a significant scientific legacy and inspiring a generation of astronomers through her work and contributions to institutions.
Before Fame
Adela Ringuelet was born on March 27, 1930, in La Plata, Argentina, a city set up in the late 1800s as a planned capital of Buenos Aires Province. It quickly became a major hub for science and education in the country. She grew up at a time when Argentine universities were expanding their programs, and the National University of La Plata had built one of Argentina's top astronomy programs through its Escuela Superior de Astronomía y Geofísica.
Ringuelet decided to study astronomy when very few women were entering the physical sciences in Argentina or anywhere else. She studied with other women who would also go on to careers in the field, like Nora Schreiber and Elsa Guttierez, pointing to a small but determined group of female astronomers from La Plata at that time. After finishing her studies, she got a job at the Félix Aguilar Observatory in 1958, beginning a long career that made her an important figure in Argentine astrophysics.
