Abstract
We consider photometric behavior of the spotted primary in V772 Her, an eclipsing system of dwarf stars (G0V + M5V), on the base of many-year multicolor photoelectric observations. The combined photometric effect due to spots can be as large as \({0}_{.}^{{\text{m}}}\)19. Our modeling demonstrated that the area of spotted regions can reach 13% of the star’s total surface area. Spots are cooler than the undisturbed photosphere by 1800 K and are located at low latitudes.
我们在多年多色光电观测的基础上，研究了V772 Her （G0V + M5V）中褐斑原星的光度行为。由斑点引起的光度综合效应可达\({0}_{.}^{{\text{m}}}\) 19。我们的模型表明，斑点区域的面积可以达到13% of the star’s total surface area. Spots are cooler than the undisturbed photosphere by 1800 K and are located at low latitudes.
