Researcher: Elijah Halliwell<\/a><\/p>\n

Observations suggest that NSVS 801195 is an eclipsing variable star of W Ursae Majoris type. This star is located at \u03b1=11:00:53.94 \u03b4=+75:33:11.26<\/a> and has the following alternate stellar designations: [GGM2006]<\/a> 827464, 2MASS<\/a> J11005394+7533113, Gaia<\/a> DR2 1080133907863717248. \u00a0Star field with the target star and comparison stars used in ensemble differential photometry are shown in Figure 1. (Not available at moment).<\/td>\n<\/tr>\n

<\/td>\n<\/tr>\n
We have observed this star with the Ball State University Observatory (BSUO) 20-inch (0.5m) telescope in the Johnson B (B) & V (V), and Cousins R (Rc<\/sub>) bandpasses. All stellar photometry is performed by the AstroImageJ (AIJ) software package<\/a>. All photometry is performed with similar ensemble stars. If a calibrated magnitude for a comparison star is known, then it is used by AIJ to calibrate the magnitude for the target star. Folded light curves for Johnson V and (B-V) color are shown in Figure 2.<\/td>\n<\/tr>\n

Best fitting Wilson-Devinney (WD) Models<\/span><\/h3>\n<\/td>\n<\/tr>\n

All modeling is performed using the PHysics Of Eclipsing BinariEs (PHOEBE)<\/a> (v0.31a) software package. PHOEBE is a graphical user interface (gui) to the WD code<\/a> that is used to model binary stars. Figure 3 shows the best fit WD model with two star spots included. Figure 4 shows a graphical representation of the stellar surface.<\/td>\n<\/tr>\n
