# QuasiNormalModes

Get the code!A Mathematica package for computing quasinormal modes (QNMs) in Schwarzschild and Kerr spacetime. The package introduces a new function

```
QuasiNormalMode[s, l, m, n, a]
```

where

$s$ - is the spin-weight of the perturbing field

$l$ - is the multipolar index

$m$ - is the azimuthal index

$n$ - is the overtone number

$a$ - is the black hole spin parameter

Currently the Schwarzschild ($a=0$) case works well. For QNMs in Kerr you are not guaranteed that the mode returned corresponds to the specified overtone number (though often it will).

### Further examples

Additional documentation can be found in the Mathematica Documentation included with the package.
