Special Session SS17  26 June 2017

Science with the BRITE-Constellation nano-satellite photometry mission

Aims and scope

BRITE-Constellation is a group of five nano-satellites - launched in 2013 and 2014 - that obtain long, uninterrupted time-series of high-precision photometry of the brightest (V < 5 mag) stars in the sky, in two passbands. This is one of the first scientific space missions accomplished with nano-satellites, cubes of 20 cm on each side. The scientific goals of the mission focus on intrinsically luminous stars, especially those that are located on the upper main sequence, i.e., hot, massive O- and B-type stars. These objects show diverse forms of variability, caused by pulsations, mass loss, rotation, stellar winds and interactions in binary and multiple systems.

The main goal of our Special Session is to present the potential and the achievements of BRITE to a broad community in order to raise its interest in the mission. To this effect, we will discuss the newest observational results obtained with BRITE-Constellation in the general context of exploiting nano-satellites for science. The aims and scope of the session can be summarized as follows:

- Explore the interaction of pulsations in massive stars with their mass loss (especially in O-type and Be stars), the presence of magnetic fields and proximity effects in binaries, with the goal of improving our knowledge of their structure and evolution.

- Promote synergies between space-based observations and ground-based observations and complementary approaches to scientific problem solving using data from different satellite missions, including BRITE.

Detailed programme will be announced later.
