Dwarf

Laying on the fresh cut grass of your lawn, you watch the sun sink behind the mountains as day subtly fades into night. There is always a minute of darkness as the city holds its breath. No street lights. No cars. Just you and the sky and… the faint glow of a star. Seeing the first star that night, you make a wish and remember the first time you saw one. You still wonder what that speck of light is—How it got to be up there, why it sometimes is so bright and other times so faint, and how it…

WHITE DWARF White dwarves (also known as degenerate dwarfs), are stellar remnants mainly composed of electron-degenerate matter and are white in color. The have a solar mass of up to 1.4, beyond this point, beyond this point, the pressure being exerted by the individual atoms is not able to hold back the gravitational pressure pulling it together The star would collapse down to a more compact object, like a neutron star or a black hole.. White dwarves are very dense, their average density being…

To take this unit to the next level, there were two things I would like to integrate: “is Pluto a planet?” and “is there life outside of our solar system?” To address the first question, I would have the students research the controversy of the dwarf planet. I would set up the research with small groups and teacher selected website as a webquest. Each student in the group will have a job…

two stars, Shaula and Lesath. The name Shaula is an Arabic word that mean the stinger, as it the star that makes up the stinger on the constellation along with Lesath. Shaula is a hot subgiant star, but the star seems to be more of a hydrogen fusing dwarf. The estimated age of the star system is about 10-13 million years, and the surface temperature is 23,000. Its apparent magnitude of 1.62 makes it one of the 25 brightest stars in the sky and it’s estimated positon is 17h33.7m, Dec. - 37°06−.…

Astronomers from the International Astronomical Union (IAU), an organization that functions as an international consensus marker in astronomy, were assigned the task of voting on the definition of planets. Some have criticized that this discussion amongst scientists was not without political and non-scientific emotions or nostalgia. One rendition of the definition would have kept Pluto as a planet and included Eris and Ceres, boosting the number of planets to twelve. Still another recommendation…

Regio. In this part, further interactions of the atmosphere and geological activities on the surface are discussed, as well as how these geological features affect the colour and brightness of the overall appearance. Introduction Pluto is a tiny dwarf planet lying at the Kuiper belt that has the largest volume and second…

less violent option. Smaller stars, up to around eight times the mass of our sun, can become a white dwarf. These old stellar remnants are incredibly dense. A teaspoon of their matter would weigh as much on Earth as an elephant – that’s 5.5 tons in one incredibly strong teaspoon. A white dwarf’s radius is just .01 times that of our Sun, but the mass is about the same. Estimating how long a white dwarf has been cooling helps astronomers increase their understanding of how old the universe really…

Is Pluto a planet? This is the question many astronomers are debating. Pluto used to be considered a planet but back in 2006, it was taken of its title and was considered a dwarf planet. Many astronomers believe Pluto is a planet, and many believe it is not. This is a modern day debate for astronomers. Pluto was first discovered in 1930 by Clyde W. Tombaugh at the Lowell Observatory in Flagstaff Arizona. Pluto is a very, very, very cold planet and is believed to be covered with ice. The…

HR Diagrams The Hertzsprung-Russell Diagram, otherwise known as HR diagram, is a graph that shows many patterns and properties of stars based on plotting them by their temperature on the surface and their light they emit, or luminosity. Created in 1912, the HR diagram was made by two astronomers, Ejnar Hertzsprung and Henry Russell who found patterns with stars’ properties. The Hertzsprung-Russell Diagram shows how every star goes through different evolutionary stages. These evolutionary stages…

a) I see White Dwarfs, Main Sequence (Dwarfs), Red Giants, Supergiants. b) White Dwarfs have luminosity from 0.001-0.02 and temperature from 7,000-24,000. Mass sequence have luminosity between 0.005-70,000 and temperature from 2,000-30,000. Red Giants’ luminosity is from 70-1000 while the temperature…
