The SARS algorithm: detrending CoRoT light curves with Sysrem using simultaneous external parameters

Aigrain, Suzanne; Guillot, Tristan; Erikson, Anders +31 more

Surveys for exoplanetary transits are usually limited not by photon noise but rather by the amount of red noise in their data. In particular, although the CoRoT space-based survey data are being carefully scrutinized, significant new sources of systematic noises are still being discovered. Recently, a magnitude-dependant systematic effect was disc…

CoRoT photometry and high-resolution spectroscopy of the interacting eclipsing binary AU Monocerotis

Amado, P. J.; Baudin, F.; Poretti, E. +15 more

Analyses of very accurate CoRoT space photometry, past Johnson V photoelectric photometry and high-resolution echelle spectra led to the determination of improved and consistent fundamental stellar properties of both components of AU Monocerotis. We derived new, accurate ephemerides for both the orbital motion (with a period of ) and the long-term…

Accretion disc in the eclipsing binary AU Mon

Djurašević, G.; Vince, I.; Latković, O. +1 more

We analyse the CoRoT and V-passband ground-based light curves of the interacting close binary AU Mon, assuming that there is a geometrically and optically thick accretion disc around the hotter and more massive star, as inferred from the photometric and spectroscopic characteristics of the binary. Our model fits the observations very well and prov…
