Reconstruction of HI power spectra with radio-interferometers to study dark energy
R. Ansari, J. -M. Le Goff, Ch. Magneville +5
Among the tools available for the study of the dark energy driving the expansion of the Universe, Baryon Acoustic Oscillations (BAO) and their effects on the matter power spectrum…
Discovery of a peculiar Cepheid-like star towards the northern edge of the Small Magellanic Cloud
J. B. Marquette, P. Tisserand, P. Francois +37
For seven years, the EROS-2 project obtained a mass of photometric data on variable stars. We present a peculiar Cepheid-like star, in the direction of the Small Magellanic Cloud,…
R Coronae Borealis stars in the Galactic Bulge discovered by EROS-2
P. Tisserand, J. B. Marquette, P. R. Wood +33
Rare types of variable star may give unique insight into short-lived stages of stellar evolution. The systematic monitoring of millions of stars and advanced light curve analysis t…
