A Partially Collapsed Sampler for Unsupervised Nonnegative Spike Train Restoration
Mehdi Chahine Amrouche, Hervé Carfantan, Jérôme Idier
In this paper the problem of restoration of non-negative sparse signals is addressed in the Bayesian framework. We introduce a new probabilistic hierarchical prior, based on the Ge…
Discovery of starspots on Vega - First spectroscopic detection of surface structures on a normal A-type star
T. Böhm, M. Holschneider, F. Lignières +8
The theoretically studied impact of rapid rotation on stellar evolution needs to be confronted with the results of high resolution spectroscopy-velocimetry observations. A weak sur…
The radius and mass of the close solar twin 18 Sco derived from asteroseismology and interferometry
M. Bazot, M. J. Ireland, D. Huber +28
The growing interest in solar twins is motivated by the possibility of comparing them directly to the Sun. To carry on this kind of analysis, we need to know their physical charact…
Estimating the p-mode frequencies of the solar twin 18 Sco
M. Bazot, T. L. Campante, W. J. Chaplin +17
Solar twins have been a focus of attention for more than a decade, because their structure is extremely close to that of the Sun. Today, thanks to high-precision spectrometers, it…
