The main goals of CASA*

The main goals of the Centre are to stimulate, perform and coordinate interdisciplinary research in astrobiology in Poland; to develop advanced technologies and to promote their commercial exploitation; to promote the collaboration on astrobiological topics of Polish research teams with other countries in Europe; to train the next generation of astrobiology researchers and to increase the public awareness for science.

 

One of our most recent results: TRAPPIST-1

The seven confirmed TRAPPIST-1 planets with masses in the terrestrial mass range orbiting very close to their central star compose a remarkable configuration: The frequencies of their revolutions form a chain of commensurabilities (resonances). In the article appeared in the Monthly Notices of the Royal Astronomical Society in June 2018, John Papaloizou, Ewa Szuszkiewicz and Caroline Terquem have linked, for the first time, the dynamics of the system to the planet habitability. The dynamical simulations performed by the authors have shown clearly that the current configuration can be understood in a natural way in terms of post formation migration together with tidal interaction with the central star acting over the lifetime of the system. One of the interesting outcomes of these simulations is that the TRAPPIST-1 system most likely consists of two subsytems merged together.
