Binary Stars Lab Report

758 Words4 Pages

Intro Binary stars consist of two stars orbiting around their common center of mass. Majority of the visible stars in the sky are binary star systems. For instance, Algol, Alpha Centauri, Sirius and Antares are binary star systems. Furthermore, the Eclipsing Binary Simulator gives individuals a visual model of how the binary stars orbit. The Eclipsing Binary Simulator also demonstrates the properties of the stars and the system orientation. Therefore, the Eclipsing Binary Simulator will allow individuals to gain a full understanding of the binary star systems.

Procedure In the first activity, I understood the purpose of the inclination and longitude controls. The purpose of the inclination control is to show the binary stars from different angles, such as looking directly down or from the side of the orbital plane. Also, the purpose of the longitude control is for the orbital plane to rotate. As a result, I noticed if the inclination was 50 degrees, then the orbital plane would be …show more content…

I also used the H-R diagram to describe the position of the stars. For instance, as I changed the temperature of the star, I realized star 1 moves closer to star 2 as the temperature decreased. In addition, I understood how the star's mass effects the system period. For example, as the mass decreases, the system period increases. In the third activity, I changed the radius of both stars and the remaining properties of the stars stayed constant. I also described the light curve as the smaller star began to touch the larger star. The light curve decreased on the y-axis and becomes a partial eclipse. Moreover, I explained why the two dips on the light curve was equal. Since, the temperature of star 1 and star 2 have the same temperature, the two dips on the light curve will be equal. As a result, I realized when the radius of the stars change, the distance of the stars also

    However, Leavitt began to notice the relation between the brightness of a star and its’ period. A brighter star would exhibit a longer period for it to be at maximum brightness, dim down to minimum brightness, and brighten back to maximum brightness again. Leavitt graphed out the relation, showing that the brightness of a star and its’ period followed a straight line. This discovery is known as the “period-luminosity relationship.”

    Starfire, a sixty-member high-school choir, is often described by alumni and current members as a group where members make practically all of their best friends. As an introvert, I joined Starfire my freshman year, unsure if I would make friends like everyone else, or if my shyness would make Starfire just a weekly extracurricular, similar to Lightshine, the middle school equivalent. But after traveling with Starfire to the United Kingdom, Northern Ireland, and Ireland, performing an original show the summer of my freshman year, I too became one of the members who had immensely strong friendships with the other members. I had some of the best experiences and realized that Starfire is an amazing group that I cannot take for granted.

    In Bryan E. Penprase’s chapter one of The Power of Stars, Penprase talks about many features of the sky that we admire every day. The general theme of this chapter in my opinion is the relevance astronomy has in our everyday lives, and how it’s been that way since the ancient times. Each culture has their own interpretation of what the sky means whether it come to festival planning, farming, harvesting, and even religious means. The ancient Indians had their lives planned around the alignment of the stars.

    A binary system is one in which the planet is not large enough to force the moon to orbit around it, but rather both bodies revolve around a central gravitational point that is created by the focus of gravity from both bodies. Earth is nearly 80 times larger than the moon and the distance between earth and the moon is also very substantial that forces the moon to orbit around the earth and create a gravitational pull on the earth that creates the phenomenon of the seas and oceans. Pluto’s moon Charon is only 8 times larger than the planet that creates the phenomenon of Binary

    Did you know that Annie Cannon was able to classify around a thousand stars a day during the peak of her career? This paper will be focusing on the life, career, and legacy of Annie Jump Cannon. Annie Jump Cannon was hired by Edward Pickering, and she worked as “Pickering’s assistant at the Harvard College Observatory” (1). After that, she was credited with coming up with an easy system that divided the stars into seven spectral classes. The spectral classes were as follows: O, B, A, F, G, K, M. Annie Jump Cannon’s career ended after forty years, but her work paved the way for women in the scientific community and continues to inspire fellow female scientists.

    Today virtually every child grows up learning that the Earth orbits the Sun, but four centuries ago the heliocentric solar system, where the Earth orbits the Sun, was so controversial that the Catholic Church classified it as a crime of heresy (UCLA). In the age of early philosophy, Socrates’ is well known. Between the Socratic method and his line of successful students, Socrates’ makes the history books. Galileo Galilei turned astronomers on their heads when he discovered moons around Jupiter. Giordano Bruno didn’t back down from any of his brilliant and different ideas.
