Modeling gravitational few-body problems with TSUNAMI and OKINAMI

Understand

In recent years, an increasing amount of attention is being paid to the gravitational few-body problem and its applications to astrophysical scenarios.

• Among the main reasons for this renewed interest there is large number of newly discovered exoplanets and the detection of gravitational waves.
• Here, we present two numerical codes to model three- and few-body systems, called TSUNAMI and OKINAMI.
• The TSUNAMI code is a direct few-body code with algorithmic regularization, tidal forces and post-Newtonian corrections.
