How to make a neutron star

Overview

My way i make a neutron star in universe sandbox 2 for who want to make a neutron star but do not know how.

First step

How to make a neutron star-first ad a red supergiant.

Supernova!

get it to supernova if it had a supergiant (red) mass it will have a nova remain. Make time about billions of years per sec to com down the nova.

Neutron star

Now the making starts why i made it to go supernova is because if not a nova remain it will turn to a black hole or scatter to fragments.
Now make it have about 10000~100000 degrees celsius.
Next make it 3 sun mass
Then,turn it about 25km it will still be a star if it was a nova remain
Next make the rotation about 1 sec.

Last (you don’t need to do this but it look good)

Make the magnetosphere strength about 10000000 Tesla ~ 1000 Tesla it will create pulsar and look great it will boom around.
Name it a “Neutron star” or whatever you want to name it.
