First Calculations of Starspot Spectra Based on 3D Radiative Magnetohydrodynamics Simulations

First Calculations of Starspot Spectra Based on 3D Radiative Magnetohydrodynamics Simulations

Accurate calculations of starspot spectra are essential for multiple applications in astronomy. The current standard is to represent starspot spectra by spectra of stars that are cooler than the quiet star regions. This implies approximating a starspot as a nonmagnetic 1D structure in radiative–conv...
