# Acoustic modes of pulsating axion stars: Non-radial oscillations

## TL;DR

This paper calculates the non-radial oscillation modes of dilute axion stars, providing insights into their vibrational properties and potential observational signatures.

## Contribution

It introduces a detailed computation of non-radial oscillation modes and associated eigenfunctions for dilute axion stars, expanding understanding of their internal dynamics.

## Key findings

- Computed lowest frequency non-radial modes
- Analyzed effective potential and eigenfunctions
- Provided frequency separations for axion star oscillations

## Abstract

We compute the lowest frequency non-radial oscillation modes of dilute axion stars. The effective potential that enters into the Schr{\"o}dinger-like equation, several associated eigenfunctions, and the large as well as the small frequency separations are shown as well.
