RZ Normae
RZ Normae is an eclipsing binary star system located in the constellation Norma. It is classified as a W Ursae Majoris variable, meaning it consists of two stars that are so close together that they share a common envelope of material, and their orbital period is very short, causing regular eclipses as each star passes in front of the other.
Due to its proximity and relatively bright apparent magnitude, RZ Normae has been extensively studied by astronomers. Analysis of its light curve reveals information about the sizes, shapes, and temperatures of the two component stars. The orbital period is typically on the order of fractions of a day.
The system's variability arises from the continuous change in the total projected area of the stars as they orbit each other, resulting in cyclical dimming of the overall brightness. The depths of the eclipses can vary, providing insights into the relative temperatures and sizes of the two stars.
RZ Normae contributes valuable data to the understanding of close binary star evolution and the dynamics of interacting stellar systems. Continued observation helps refine models of stellar structure and the processes involved in mass transfer and mixing within these close binary systems.
