TL;DR
This paper introduces a tomographic method to analyze velocity fields in the atmosphere of the red supergiant star {d} Cep, linking atmospheric motions to observed photometric variability.
Contribution
It applies a novel tomographic technique to both observational data of {d} Cep and 3D simulations, enhancing understanding of stellar atmospheric dynamics.
Findings
Velocity fields at different depths are characterized.
Atmospheric motions are correlated with photometric variability.
Method provides new insights into stellar atmosphere structure.
Abstract
A tomographic method, aiming at probing velocity fields at depth in stellar atmospheres, is applied to the red supergiant star {\mu} Cep and to snapshots of 3D radiative-hydrodynamics simulation in order to constrain atmospheric motions and relate them to photometric variability.
