We determined the elements and compounds of the stars by the size and mass of the star. Also where it is located in our solar system. Some stars contained many elements as many as 4 main elements. But some had as little as 2 and 3 main elements. You can tell the temperature by looking on how much energy and light the star gives off. Hotter stars have negative B-V indices, and cooler stars have lower B-V indices. HR diagrams tell you the relationship between a stars temperature and luminosity.
[27] Scientists can determine what a distant star is made of by looking at ____.
Isabel Wilkerson is an African American Howard University journalism graduate writer and the first black woman in the history of American Journalism to win a Pulitzer Prize. Among her notable works is the novel “The Warmth of Other Suns”. The novel The Warmth of Other Suns was about the Great Migration which occurred between the years 1915-1970 and this was the movement of approximately seven million Black people out of the Southern United States to the North, Midwest and Western states from 1916 to 1970. Blacks migrated to escape widespread racism in the South, to seek employment opportunities in industrial cities of the North, to get better education for their children, and to pursue what was widely
The data that we collected was the flame color, the colors on the emission line spectrum, and their corresponding estimated wavelength numbers. We collected this data because we thought that it would help us the most with matching up the known to the
Throughout this semester we have done multiple writings, that have covered many of the readings done in the course. We started with our Warmth of Other Suns (WOOS) paper, then our legacy interview that connected to the WOOS paper. After completing those to essays we worked on a movie review for “In America” and then our own personal migration.
5. On what kind of diagram are stars plotted according to their surface temperature and luminosity?
The star basically blasts apart and sends iron flying. These stars are common, and so are the elements created at its core, one of them being iron. Gold is rarer, because it is created by the collision of dead stars. Each element is a pure element, with a unique number of protons. You would have to change the number of protons to change an element. You cannot do that with any
By using the line spectrum astronomers can determine the composition of stars by observing the colors that are produce when using a line spectrum and comparing it to known elements and their signature colors on a line spectrum. Each element has a signature color line patter when observed on a line spectrum, because each element has a different number of electrons which give off different amounts of energy when jumping down sub-levels when excited. Scientists can use both of these tests by observing the colors given off, to help them determine the identity of an element, whether in a solid or gaseous
I can tell many things about the star B-Centauri by looking at this H-R diagram. First of all I can see that it has a temperature of almost 30,000 K, that means it is almost five times hotter than our sun. Next, B-Centauri's luminosity is 10, 000 Lu which means it produces ten thousand times the energy of our sun. I know that B-Centauri is a spectral type O by reading the H-R diagram. During the Vlab we found that Naos was a spectral type O. All stars that are spectral type O are blue, meaning they are the hottest type of stars. Stars of the same spectral type have the same composition. Since Naos has hydrogen, helium, and helium ions so does B-Centauri. The mass of B-Centauri is twenty times the mass of our sun. The radius of B-Centauri

In the current world that Light from a Distant Star takes place in, social class, physical appearance, and past serve as the foundation of inevitable stereotypes society will place upon someone. In the book Light from a Distant Star, characters Max and Dolly are stereotyped from the very beginning. Max is a former inmate with a troubled past who is inaccurately characterized as a violent man with no control of his temper. Dolly is a failing aspiring Broadway performer, having to settle with being a dancer, which ultimately defines her as a floozy. Author Mary McGary Morris, actively shows the reader how these stereotypes are formed based upon individual beliefs, actions, social class and lack of power. These stereotypes both accurately and inaccurately characterize Max and Dolly, who both lack a voice, and are unable to defend their current and past involvements.
Ancient astronomers were able to differentiate between stars and planets, as stars remain relatively fixed over the centuries while planets will move an appreciable amount during a comparatively short time.
The star I chose was Vega. From looking at the H-R diagram Vega's spectral type is A, It was a little to the left of A. A is an average temperature right in the middle H-R diagram basically. Which means the temperature is close to 9000k, Vega's temperature is 9546 kelvin which is 3722 kelvin more than our sun. Next Vega has mainly calcium and hydrogen nothing else that's it. The color of the star is white, Vega was in the middle of being blue or white kinda mixed from looking at the H-R diagram. Next the mass of the star Vega is 3m, and the radius of Vega is 1 solar radius. Vega is a main sequence star that means it still is young and that it still has hydrogen to fuse into helium and it's still got time till it go's out. The most interesting
The changes that occur during a star 's life are called stellar evolution. The mass of a star determines the ultimate fate of a star. Stars that are more massive burn their fuel quicker and lead shorter lives. Because stars shine, they must change. The energy they lose by emitting light must come from the matter of which the star is made. This will lead to a change in its composition. Stars are formed from the material between stars, shine until they exhaust their fuel, and then die a predictable death based upon their initial mass.
Indecent bodies like the sun. Stars are made up of big exploding balls of gas, mostly hydrogen and helium. The sun is similarly a star made up of huge amounts of hydrogen, undergoing a continuous nuclear reaction like a hydrogen bomb. Stars come about when vast clouds of hydrogen, helium and dust contract and collapse due to gravity. The clouds came from astronomical plasma from “The Big Bang”, but the dust comes from the supernovae of other stars.
