White dwarf

Stellar Nebula : This is a cloud full of superheated gases. They range in size from millions of miles across to hundreds of light years across. This Nebula appears larger but is barely visible in the sky. Some Nebulas can be seen with a naked eye, this one can not because it does not glow as bright as others. This star isn’t as bright as others because it is larger.…

here on Earth. There are hundreds upon thousands of stars that take on many different sizes and colors. Depending on the size of the star from its birth, the star could take two paths at the end of its life: turn into a nebula leaving behind a white dwarf, or the star could burst in a fierce supernova explosion. Either road the star chooses to go on, determined by the mass of course, the process still takes billions of years. The life cycle of a star, although lengthy, is the rawest and most…

the state of equilibrium. Once it’s there it’s is considered a pre-main sequence star, but once it starts to acquire energy from nuclear reactions the protostar is now a main sequence star. If they never reach nuclear fusion, then they become brown dwarfs, stars that never…

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…

Solar cores of high temperatures, generate energy quicker, therefore higher temperature stars are more luminescent. Stars located on the main sequence, referred to as “dwarfs”, must generate power through hydrogen and helium nuclear fusion in their solar core and be in thermal equilibrium, the balance between luminosity and energy generation, and hydrostatic equilibrium, equality between pressure and gravity. Following…

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…

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…

are red. At half the temperature, stars that are yellow are classified with B. Next up, is A which includes stars with a surface temperature of 10,000 Kelvin that are orange. White stars that have a temperature of 8,000 degrees are identified with the letter F. Stars with the spectral class of G are 6000 Kelvin and either white or blue. The final 2 letters, K and M, both include stars that are blue, but stars in the spectral class of K are 4000 Kelvin while stars in the spectral class of M are…

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…

the Sun, the temperature is approximately 17,000 F (9,500C), the luminosity is about 40 times the Sun’s size, and the star type is is a white main sequence star, so it is in A class. Since it is a main sequence star, it fuses hydrogen into helium in its core, The Vega star is also known as the Alpha Lyrae and is in the Lyra constellation. It is a blur to white star and has a radius of 1.1 million miles, 2.5 times larger than the sun. The Vega star is…
