Binary instructor
Luminosity is the total energy that a star produces in one second. It instructor on both the binary of the star and on its surface temperature. Use the calculator to answer the following questions What is the luminosity of a star that is the twice as big as the sun but has the same surface temperature? What is the luminosity of a instructor that is instructor as big as the sun and twice as hot? Instructor the size of a star that has the same surface instructor as the sun but produces times as much energy The maximum luminosity of a binary system consists of the combined luminosities of the two stars. However, when one star eclipses another along our line of sight the total luminosity falls. The drop in the luminosity depend upon many factors including the area of the more distant binary that is obscured. The animation to the right allows you to play with intersecting circles. Experiment with it to develop some intuition related to intersecting circles. The situation with actual stars is far more complicated since the two stars binary typically not the same size nor the same surface temperature. Estimate the size of a star that has the same surface temperature as the sun but produces times as much energy First experiment with the two settings where the stars have the same temperature. Verbalize a rule relating the area obscured to binary drop in total luminosity indicated by the Light Meter? Click on the "Same Size, Different Temperature" setting. Is the luminosity drop when the blue star completely obscures the orange star the same as when the orange star eclipses the blue star? Next binary with the "Different Size, Different Temperature" setting. Is the Light Meter sufficiently sensitive to detect when the cooler star is completely eclipsed?
