article_snippet: And once inside, The bold new theory affects the movement of heat within our solar system's star - which could explain why scientists have struggled to explain 'pressure waves' inside the sun.
article_snippet: This would help explain how pressure waves move around the sun.
article_snippet: So far, a new model for the sun has proved successful in calculating the sun’s density and temperature - but measuring 'pressure waves' in a new model for the sun interior has proved much more difficult.
article_snippet: Pressure waves are produced as a result of activity on the solar surface.
article_snippet: Pressure waves in the sun are produced as a result of activity on the solar surface, shown here in this illustration.
article_snippet: This would explain why observations of pressure waves in the sun namely how Red and blue denote different directions for the waves move, and how heat is transported - do not match up with theories of solar behaviour.
