Literatürde ayrıntılı bir fotometrik çalışması bulunmayan KP And örten çift yıldız sisteminin Transiting Exoplanet Survey Satellite (TESS) uydu gözlemlerinden elde edilen ışık eğrisi ilk olarak bu çalışmada modellenmiştir. Sistemin TESS gözlemlerinden hesaplanan minimum zamanları kullanılarak güncel ışık elemanı elde edilmiştir. Çözüm sonucunda ayrık bir çift yıldız sistem olduğu görülen KP And sisteminin ışık eğrisi çözüm parametreleri kullanılarak sistemin mutlak parametreleri M_1=1.67±0.17 M_⊙, R_1=2.20±0.14 R_⊙ ve M_2=0.36±0.10 M_⊙ , R_2=1.56±0.26 R_⊙ olarak tahmin edilmiştir.
