BRITE (BRIght Target Explorer) Constellation is a network of five nanosatellites to investigate stellar structure and evolution of the brightest stars in the sky and their interaction with the local environment. Micropulsation, wind phenomena, and other forms of stellar variability are recorded via high precision photometry in two colours (red and blue). The massive BRITE target stars are extremely important in producing the chemical elements in our universe and recycling them in winds and supernovae. They are “laboratories” that help us to understand a wide range of astrophysical processes in our universe.
The BRITE nanosatellites operate in low-earth-orbits which allow for a superior time coverage and data length, not obtainable from ground. Both are crucial for a detailed asteroseismic study, which also benefits from two-colour information.
