Advanced MOST Science Archive (AMSA)

Microvariability and Oscillations of Stars (MOST) is a Canadian microsatellite designed to monitor optical variability in a few stellar targets for up to 60 days; it was launched in 2003. As the first telescope dedicated to asteroseismology, it was a pathfinder for the subsequent Convection Rotation and Planetary Transits (COROT) and Kepler missions and is still in operation. Canadian Space Agency (CSA) ceased operations support in 2014. The device measured the oscillation in light intensity of stars in order to determine their composition as well as age. It also measured transit of known exoplanets. The data is also published by the Canadian Astronomy Data Center (CADC) (http://www.cadc-ccda.hia-iha.nrc-cnrc.gc.ca/en/).
