First release of PLATO consortium stellar limb-darkening coefficients by Giuseppe Morello et al. on Wednesday 30 November

We release the first grid of stellar limb-darkening coefficients (LDCs) and

intensity profiles (IPs) computed by the consortium of the PLAnetary Transits

and Oscillations of stars (PLATO), the next medium-class (M3) mission under

development by the European Space Agency (ESA) to be launched in 2026. We have

performed spectral synthesis with \texttt{TurboSpectrum} on a grid of

\texttt{MARCS} model atmospheres. Finally, we adopted \texttt{ExoTETHyS} to

convolve the high-resolution spectra ($R=2\times10^5$) with the

state-of-the-art response functions for all the PLATO cameras, and computed the

LDCs that best approximate the convolved IPs. In addition to the PLATO

products, we provide new LDCs and IPs for the Kepler mission, based on the same

grid of stellar atmospheric models and calculation procedures. The data can be

downloaded from the following link:
