Too Long; Didn't Read
Stars that are both pulsating and eclipsing offer an important opportunity to better understand many of the physical phenomena that occur in stars.

7 PHYSICAL PROPERTIES
We determined the physical properties of KIC 9851944 from the spectroscopic and photometric results obtained above. For this we used the JKTABSDIM code (Southworth et al. 2005), modified to use the IAU system of nominal solar values (Prša et al. 2016) plus the NIST 2018 values for the Newtonian gravitational constant and the Stefan-Boltzmann constant. Errorbars were propagated via a perturbation analysis. The results are given in Table. 7.
