Encyclopedia
Jørgen Christensen-Dalsgaard (born 6 October 1950) is a Danish astronomer at Aarhus University in Denmark
. He specializes in asteroseismology
and helioseismology
to which he has made significant contributions including predicting the oscillation of Sun-like stars in 1983. He is the head of "Rumudvalget" (the comity of space of the Danish Ministry of Science, Technology and Innovation) and the Danish AsteroSeismology Centre (DASC). He is co-investigator on the Kepler mission
and the 300 researchers in the Kepler Asteroseismic Science Consortium (KASC) are led by him and Søren Frandsen in Aarhus. KASC are a part of the Kepler Mission
; they are responsible for the asteroseimology part of the Kepler. Dalsgaard has published several papers on this subject.
He has been featured on Danish television and radio several times and have given many free public lectures on astronomy and asteroseismology. He has published over 200 articles
Denmark
Denmark is a Scandinavian country in Northern Europe. The countries of Denmark and Greenland, as well as the Faroe Islands, constitute the Kingdom of Denmark . It is the southernmost of the Nordic countries, southwest of Sweden and south of Norway, and bordered to the south by Germany. Denmark...

Asteroseismology
Asteroseismology also known as stellar seismology is the science that studies the internal structure of pulsating stars by the interpretation of their frequency spectra. Different oscillation modes penetrate to different depths inside the star...
and helioseismology
Helioseismology
Helioseismology is the study of the propagation of wave oscillations, particularly acoustic pressure waves, in the Sun. Unlike seismic waves on Earth, solar waves have practically no shear component . Solar pressure waves are believed to be generated by the turbulence in the convection zone near...

Kepler Mission
The Kepler spacecraft is an American space observatory, the space-based portion of NASA's Kepler Mission to discover Earth-like planets orbiting other stars. The spacecraft is named in honor of the 17th-century German astronomer Johannes Kepler...
