CARPP is a powerful tool for analyzing dense molecular cores using multi-wavelength dust continuum observations. It leverages 3D radiative transfer under spherical symmetry to derive density, temperature profiles, and spectral index, enabling researchers to distinguish between hydrostatic equilibrium (Bonnor-Ebert spheres) and dynamically collapsing cores (power-law profiles).
- 3D Radiative Transfer Modeling: Accurately accounts for temperature gradients and optical depth effects.
- Multi-Wavelength Data Fitting: Optimizes density and temperature profiles using dust continuum images at different wavelengths.
- Flexible Profile Models:
- Generalized Plummer-like density profiles (supports Bonnor-Ebert spheres and power-law regimes).
- Continuous temperature profiles with customizable central and ambient parameters.
- Robust Performance: Achieves <10% average parameter error under optimal noise/resolution conditions.
The CARPP package in this repo is the IDL version of CARPP. To use CARPP, you should:
- Download the repo
- Make sure you have IDL installed on your device
- Add the path of CARPP to your IDL at
Preferences - IDL - Paths - Do
idl run_carpp.proinTest_Datafolder, it should start to calculate the test core - You may now edit and run
