+abstract: >-
+  We present a python package ldtk that automates the calculation of custom
+  stellar limb-darkening (LD) profiles and model-specific limb-darkening
+  coefficients using the library of phoenix-generated specific intensity
+  spectra by Husser et al. The aim of the package is to facilitate analyses
+  requiring custom generated LD profiles, such as the studies of exoplanet
+  transits -- especially transmission spectroscopy, where the transit modelling
+  is carried out for custom narrow passbands -- eclipsing binaries,
+  interferometry, and microlensing events. First, ldtk can be used to compute
+  custom LD profiles with uncertainties propagated from the uncertainties in
+  the stellar parameter estimates. Secondly, ldtk can be used to estimate the
+  LD-model-specific coefficients with uncertainties for the most common LD
+  models. Thirdly, ldtk can be directly integrated into the log posterior
+  computation of any pre-existing modelling code with minimal modifications.
+  The last approach can be used to constrain the LD model parameter space
+  directly by the LD profile, allowing for the marginalization over the LD
+  parameter space without the need to approximate the constraint from the LD
+  profile using a prior.
