@article{Corsaro2014DIAMONDSAN, title={DIAMONDS: A new Bayesian nested sampling tool - Application to peak bagging of solar-like oscillations}, author={Enrico Corsaro and Joris De Ridder}, journal={Astronomy and Astrophysics}, year={2014}, volume={571} }

Context. Thanks to the advent of the space-based missions CoRoT and NASA’s Kepler, the asteroseismology of solar-like oscillations is now at the base of our understanding about stellar physics. The Kepler spacecraft, especially, is releasing excellent photometric observations of more than three years length in high duty cycle, which contain a large amount of information that has not yet been investigated. Aims. To exploit the full potential of Kepler light curves, sophisticated and robust…
