Neutron Star SHOWCASE

What you are seeing: a rotating 1.4 M_sun neutron star rendered through five modes (Overview, Lighthouse, Magnetar, Structure, Spindown). The same NS object is shared across modes so you build one mental model of the second-most-extreme object in the universe. Drag the canvas to orbit the camera, scroll to zoom

Figure 1. Neutron Star, mode-switchable laboratory. Method: 3D Canvas2D depth-sorted sphere + magnetic-dipole field-line geometry + Gaussian beam pulse profile + parametric SLy/APR/FPS mass-radius curves + classical magnetic-dipole spindown + magnetar-flare profile + vortex-unpinning glitch.

WHAT TO TRY

Cycle the five modes: the dipole-and-beam overview, the lighthouse pulse profile, a magnetar flare, the TOV mass-radius structure, and spin-down with a glitch, all for one 1.4 solar-mass star.
Change the equation of state (SLy, APR, FPS): the mass-radius curve stiffens or softens, the open question that gravitational-wave and NICER measurements are closing in on.
Tilt the magnetic axis alpha against the spin: the beam sweeps past the line of sight once per rotation, the lighthouse that we detect as a pulsar.
