摘要: The high performance photometric data obtained with space mission CoRoT offer the opportunity to efficiently constrain our models for stellar interior of solar-like pulsating stars. On occasion analysis oscillations pulsator HD 49385, a G0-type star in an advanced stage evolution, we revisit phenomenon avoided crossings. Christensen-Dalgaard proposed simple analogy describe crossing between two modes. We here present extension this case n modes, and show that it should lead, certain cases, characteristic behavior eigenfrequencies, significantly different from n=2 case. This type seems be observed which infer Post Main Sequence phase.
