Mapping 3D to 1D (In Progress!)

We will be mapping or 3D hydrostatic TŻO models into MESA to further investigate the physical parameters of our objects.

How often are TŻOs formed?

Understanding TŻO formation rates can provide important information on the current number of TŻOs within the Milky Way and the Magellanic Clouds. Having that context is crucial if we want to search for more candidates. Accurate TŻO formation rates can also hint to the longevity of these objects.

Simulating TŻO Formation

A TŻO can be created when a newly formed neutron star (NS) gets “kicked” into its companion star, which we call the “impact scenario”.

Using a moving mesh solver (MANGA) on top of the smooth particle hydrodynamics (SPH) code, Charm N-body GrAvity solver (ChaNGa), we simulated 5 main sequences (MS) masses spanning 5 - 15 solar masses, with three different periastron distances ( $r_p$ ).
