Jørgen Christensen-Dalsgaard

Jørgen Christensen-Dalsgaard (born 6 October 1950) is a Danish astronomer at Aarhus University in Denmark. He specializes in asteroseismology and helioseismology. He has made significant contributions to both fields, including predicting the oscillation of Sun-like stars in 1983.^[1] He is the head of "Rumudvalget" (the committee of space of the Danish Ministry of Science, Technology and Innovation)^[2] and the Stellar Astrophysics Centre (SAC) supported by the Danish National Research Foundation. He is co-investigator on the Kepler mission^[3] and, with Hans Kjeldsen in Aarhus, leads the 500+ researchers in the Kepler Asteroseismic Science Consortium (KASC).^[4] KASC is responsible for the asteroseismology component of the Kepler mission. Christensen-Dalsgaard has published several papers on this subject.^[5] He was also previously the president of Commission 27 of the International Astronomical Union.^[6]
