Sachiko Tsuruta

from Wikipedia, the free encyclopedia

Sachiko Tsuruta is an American astrophysicist.

Life

Tsuruta earned her bachelor's degree from the University of Washington in 1956 and her master's degree from Columbia University in 1959 , where she received her PhD in 1964 (Dissertation: Neutron Star Models ). She is a professor at Montana State University .

Even as a doctoral student, Tsuruta predicted the existence of neutron stars in the form of pulsars (1967) before they were discovered. In addition, she made verifiable statements about their thermodynamic behavior (heating and cooling) through observation, which were also confirmed. She models the matter in neutron stars with superfluid condensates of pions and kaons and quarks.

In addition to neutron stars, she also deals with other compact stellar objects such as black holes (including supermassive black holes and the ultra-hot plasma in their environment), white dwarfs, models of active galaxy nuclei (AGN, e.g. quasars ) and their energy sources and problems of the early universe like the first stars, with gravitational waves and gamma-ray flashes.

In 2015 she received the Marcel Grossmann Award in particular for her work on neutron stars. In 2016 she was a visiting researcher at the Kavli IPMU Institute in Tokyo.
