Listening to the music of red giant stars using Asteroseismology

Chen Jiang

In 1926 in the opening paragraph of his now-classic book, The Internal Constitution of the Stars, Sir Arthur Eddington lamented, ‘What appliance can pierce through the outer layers of a star and test the conditions within?’ There is now an observational answer: asteroseismology, the real music of the spheres. In the talk, I will review my work on the oscillations of red giant stars using asteroseismology. The long-term NASA’s Kepler space observations provide excellent photometric data for the detection of solar-like oscillations that are the sounds of these stars. I will introduce how to interpret these oscillations observationally and theoretically, which contribute to the understanding of inner structure as well as the evolution of red giant stars.

Institute of Astrophysics and Space Sciences

Institute of Astrophysics and Space Sciences (IA) is a new but long anticipated research infrastructure with a national dimension. It embodies a bold but feasible vision for the development of Astronomy, Astrophysics and Space Sciences in Portugal, taking full advantage and fully realizing the potential created by the national membership of the European Space Agency (ESA) and the European Southern Observatory (ESO). IA resulted from the merging the two most prominent research units in the field in Portugal: the Centre for Astrophysics of the University of Porto (CAUP) and the Center for Astronomy and Astrophysics of the University of Lisbon (CAAUL). It currently hosts more than two-thirds of all active researchers working in Space Sciences in Portugal, and is responsible for an even greater fraction of the national productivity in international ISI journals in the area of Space Sciences. This is the scientific area with the highest relative impact factor (1.65 times above the international average) and the field with the highest average number of citations per article for Portugal.
