Tomographic imaging of lete-type stars from spectroscopic and photometricrotational modulation. I. Principle and mathematical formulation of the method.
Abstract
The paper describes the principle of and the methods for the flux rotational modulation imaging of late-type stars. The full mathematical formulation of the problem of indirect stellar imaging from projections is presented in terms of matricial formalism. The performance and the intrinsic limitations of the method are demonstrated, using the indirect imaging code built on the basis of the developed approach to reconstruct an input image from a series of generated noisy spectra.
