Early Life and Education
María Teresa Ruiz was born in Santiago de Chile in 1946. In 1966, she started studying chemical engineering at the University of Chile. But during an astronomy summer school, she found her true passion. She then switched to the new astronomy program at the University of Chile. In 1971, she was the very first person to graduate from this program.
Career and Discoveries
In 1975, María Teresa Ruiz earned her PhD in astrophysics from Princeton University. She was the first woman ever to do so. After her studies, she worked as a researcher in Italy and Mexico.
In 1997, she received Chile's National Prize for Exact Sciences. This made her the first woman in Chile's history to win this important award.
Discovering Kelu-1
In 1997, María Teresa Ruiz made an exciting discovery: Kelu-1. This is a system made of two brown dwarf stars. Brown dwarfs are like "failed stars" because they are not big enough to burn like regular stars. Kelu-1 was also one of the first "free-floating" brown dwarfs found. This means it doesn't orbit a larger star.
Kelu-1 is located in the Hydra constellation. It is about 61 light-years away from Earth. When María Teresa Ruiz first saw Kelu-1, she was surprised. Its light spectrum was different from anything she had seen before. But she found lithium in the star and noticed it was very red. These clues helped her confirm it was a brown dwarf.
The name "Kelu" comes from the Mapuche language. It means "red," which describes the star's color.
