spotter.doppler

spotter.doppler#

Doppler and spectral calculations for rotating stars.

This module provides functions to compute disk-integrated spectra, radial velocity maps, and related quantities for stars with non-uniform surfaces.

Functions#

spectrum(→ jax.typing.ArrayLike)

Compute the integrated spectrum of a rotating Star.

transit_spectrum(→ jax.typing.ArrayLike)

Compute the integrated spectrum of a rotating Star.

rv_design_matrix(→ jax.typing.ArrayLike)

Compute the radial velocity design matrix for a Star.

radial_velocity(→ jax.typing.ArrayLike)

Compute the disk-integrated radial velocity of a Star.
