First Calculations of Starspot Spectra based on 3D Radiative Magnetohydrodynamics Simulations
H. N. Smitha, Alexander I. Shapiro, Veronika Witzke +6
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 c…
Reliable Transmission Spectrum Extraction with a Three-Parameter Limb Darkening Law
Rosa E. Keers, Alexander I. Shapiro, Nadiia M. Kostogryz +7
Stellar limb darkening must be properly accounted for to accurately determine the radii of exoplanets at various wavelengths. The standard approach to address limb darkening involv…
The PLATO Mission
Heike Rauer, Conny Aerts, Juan Cabrera +842
PLATO (PLAnetary Transits and Oscillations of stars) is ESA's M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large numb…
Stellar Surface Magnetic Fields Impact Limb Darkening
Nadiia M. Kostogryz, Alexander I. Shapiro, Veronika Witzke +8
Stars appear darker at their limbs than at their disk centers because at the limb we are viewing the higher and cooler layers of stellar photospheres. Limb darkening derived from s…
