Chabrier 2003 IMF (https://arxiv.org/abs/astro-ph/0304382)

Functions

chabrier(mass, params)

Wrapper for the Chabrier IMF using a parameter dictionary.

chabrier_imf_raw(mass[, m_min, m_max])

Returns the normalized Chabrier IMF evaluated at mass, combining a log-normal and power-law form, fully JAX-compatible.
fastar.imf.named_imf.chabrier.chabrier(mass, params)[source]#

Wrapper for the Chabrier IMF using a parameter dictionary.

Parameters:

  • mass (array-like) – Stellar mass or array of masses.

  • params (dict) – Dictionary of parameters to pass to chabrier_imf_raw.

Returns:

Normalized IMF values.

Return type:

jnp.ndarray or float

fastar.imf.named_imf.chabrier.chabrier_imf_raw(mass, m_min=0.1, m_max=100.0)[source]#
