The Ariel 0.6 - 7.8 μm stellar limb-darkening coefficients

We provide here tables of stellar limb-darkening coefficients (LDCs) for the Ariel ESA M4 space mission. These include LDCs corresponding to different wavelength bins and white bands NIRSpec, AIRS-Ch0 AIRS-Ch1 spectrographs, those VISPhot, FGS1 FGS2 photometers. The are calculated with open-source software ExoTETHyS three complete grids atmosphere models obtained ATLAS9 PHOENIX codes. model complementary, as code adopts more modern input physics spherical geometry, while cover wider ranges parameters. from in compared main text. All together following effective temperature ($1\,500 \, K \le T_{\mbox{eff}} 50\,000 K$), surface gravity (0.0 dex $\le \log{g} 6.0$ dex), metallicity ($-5.0 [M/H] 1.0$).
