How to Explore the Helioseismology Sun Oscillation 3D Explorer
Open the Helioseismology Sun Oscillation 3D Explorer, watch the rippling surface, then toggle the interior cutaway to see the real measured boundary the ripple pattern helps astronomers find.
- Open https://freetoolonline.com/space-3d/helioseismology-sun-oscillation.html and wait for the rippling sphere and the facts panel to render.
- Drag the wave amplitude slider to make the ripple pattern easier or harder to see.
- Click "Next wave pattern" to cycle through three simplified example oscillation patterns.
- Click "Show interior cutaway" to switch to a cross-section showing the measured 0.713-solar-radii convection-zone boundary and the tachocline.
- Drag to orbit and scroll or pinch to zoom for a closer look.
- Read the facts panel for the oscillation period, mode count, and boundary figures.
Key published figures
| Figure | Value |
|---|---|
| Oscillation period | about 5 minutes (about 3 mHz) |
| Resonant modes tracked | millions, via SOHO / GONG / SDO-HMI |
| Measured convection-zone base | 0.713 +/- 0.001 solar radii |
| Tachocline location | about 0.69-0.72 solar radii; thickness about 0.006-0.05 solar radii |

Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
- Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
- Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
- Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
