Abstract:
We present an extensive high-precision light curve of the bright star
psi Centauri, obtained with the star tracker on board the WIRE
satellite, which shows that this star is an eclipsing binary. We have
obtained photometry from the SMEI instrument on board the Coriolis
satellite, which together with the WIRE data allows us to determine
the orbital period and photometric parameters of the eclipsing system.
The WIRE light curve contains 41334 datapoints with a point-to-point
scatter of 2mmag and a total length of 28.7days. The SMEI light
curve contains 3448 datapoints with a point-to- point scatter of
20mmag and spas several observing seasons.
