A Danish space project: MONS - measuring oscillations in nearby stars Original Research Article

The MONS (Measuring Oscillations in Nearby Stars) project on the Rømer satellite aims at studying properties of stellar interiors through observations of oscillations in stellar luminosity and surface temperature. The main targets are stars exhibiting oscillations similar to those observed in the Sun, with very low amplitudes. During the planned two-year life time of the mission, around 20 such stars will be observed with the MONS Main Telescope. Additional data on variability of a large number of stars of a broad range of types may be obtained from the parallel science programme. This part of the programme will use two instruments; The Star Trackers and the Field Monitor. The following paper aims at describing some aspects of the MONS project.
