The Star B-Centauri

I pick the star Antares, from the H-R diagram I can tell that it it is a Red Supergiant, and it has a surface temperature that is around 3,000 degrees kelvin, which is cooler than the Sun by at least 2,000 degrees kelvin, but its luminosity is around 10,000 solar units, which means it produces much more energy than our Sun does, so it is a lot brighter. The spectral type of Antares is a M, I could tell that its spectral type was M because I read the H-R Diagram, the VLab told me that the star ‘Betelgeuse’ has a spectral type of M, and Antares is right below, and basically inside Betelgeuse. Stars with the same spectral type have the same chemical composition, so Antares has the chemical composition Ca (calcium), TiO (titanium oxide), CH (methylidene).

As a tactical response to the regional deficit of primary care providers and a marked stressing of local emergency departments along with urgent care facility resource overburden, Alpha Centauri has been developed from the ground-up as a premier walk-in healthcare entity in Elk County, Pennsylvania. We endeavor to provide quality healthcare in the vein of three key specializations necessary in our region: orthopedics, gastroenterology, and pediatrics. These specialties are often the most sought out after residential patients are referred from local urgent care and emergency departments, and our primary goal is to deliver these vital services to our patients without delay, and prioritize the care needed without the potential of degenerating conditions caused by the inability of local health systems to deliver this care in a timely manner. The initial vision and groundwork is what will become three separate walk-in clinics based on our current specialization capacities, the first and primary of which will be made ready for clientele on February 15th, 2017.

Copper Sun is a very dark and tragic story. A young adult named Amari, whos village was raided, was abducted into slavery and forced to work in a rice plantation. Copper Sun is the tale of how Amari overcomes the pain thrown at her in which she undergoes in harsh and terrible conditions.

In the essay “Finding Another Earth,” author Pat Brennan, PlanetQuest reports the new finding planet same as our home planet. The author says a habitable zone shows the band of congenial temperatures for planetary orbits. It can say which planet has a habitable zone and could have water on its surface. The author explains that planets in habitable zones or not depend on many factors like if it’s very near from its star and it been to hat and can’t be a habitable zone. Kepler-452b is the most similar to the Earth-sun system found yet. Although Kepler-452b is the most similar to the Earth, other planets are nearly similar to the Earth too. Before Kepler-452b was found, the planet Kepler-186f held the “most similar”. Kepler-186f has a 130 days

In the constellation Centaurus, there is a star system named Alpha Centauri in which there are three stars. Both A and B are approximately the same size as our sun

The nearest star to our solar system is Alpha Centauri which is about 4.37 light years away from our Earth, which equates to about 25 trillion miles from our Earth. Using traditional spacecraft, it would take us about 165,000 years to reach Alpha Centauri. Now I will be planning a trip to the star to observe if there is any life on one of its planets and will be providing step by step details of my journey. I will travel to Alpha Centauri by myself, not with a spaceship, but with a Solar Sail. Solar Sails are a cost effective way of traveling to stars and planets outside of the solar system. The biggest benefit with a Solar Sail is that it does not require any rockets to propel it nor any fuel. It uses radiation pressure from stars to push

DX Cancri is a pretty small star. Its spectral type is M and it is made up of helium and methylidyne. Its temperature is about 3000 kelvin. The color is red and it is a main sequence dwarf star. The luminosity is 10-4 and the mass is 0.1 and the sun’s mass is 1. The radius is 10-3 and after the cycle of a dwarf star, it cools down and turns into a black dwarf star. Even though it is a lot smaller than the sun, it is still many times larger than Jupiter, the largest planet in our solar system!

It’s a world at least 1.3 times as massive as Earth that orbits a dim star 4.2 light-years away. That star, alled Proxima Centauri, is the one closest to our sun. Its newly discovered planet whips around its star so fast that each year on that world lasts a mere 11.2 days. That reflects the fact that this planet is so close to its sun — just 5 percent as far as Earth is from our own sun. Yet that other world is at just the right distance from its star for any liquid water to still be able to flow on its

A star's life cycle is determined by its mass. The larger its mass, the shorter its life cycle. A star's mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born. As the interstellar mass condenses and loses gravitational potential energy, the temperature rises and the material gains thermal energy which is known as protostar. It is now a main sequence star and will remain in this stage, shining for millions to billions of years to come. As in sequence star glows, hydrogen in a star’s core is converted into helium, the core begins to contract and heat up. The rapid release energy upsets the pressure-gravity force balance and causes the star to expand, cool down and enter

The Hertzsprung-Russell Diagram is a graph to show how the temperature and brightness of stars are related. The Y axis of the Hertzsprung Russell Diagram is the absolute brightness of the stars. This axis’ brightness is increasing from the bottom of the axis to the top. The X axis shows the surface temperature of the stars. This axis shows a decreasing of the surface temperature from left to right. The graph, is color coordinated. The colored categories start on the left from blue, white, yellow, orange, and then red on the very right side. The hottest stars are in blue category. The coldest stars are in the red category. The brightest stars are near the top of the diagram and on the bottom are the dimmest. In the eighth grade science textbook, it states “Astronomers use H – R diagrams to classify stars and to understand how stars change over time.” In the HR diagram there are white dwarfs, supergiants, giants, and the main sequence which is a the pattern of a diagonal line.

Circumpolar stars are stars that are visible throughout the entire year because their path is always above the horizon. Circumpolar stars are located near celestial poles, so they travel in a smaller circle around the pole. Because stars that are farther away from the celestial poles travel in larger circles, their path is sometimes hidden by the horizon. According to the diagram on p. 29, more stars are circumpolar at the North Pole because it is directly beneath the north celestial pole. Standing at the North Pole, you would be able to see the entire path of all of the stars north of the celestial equator.

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

A H-R diagram plots a star’s luminosity against its temperature or color. The vertical axis is the stars luminosity relative to the sun (1 L0 is the luminosity of our sun) and the horizontal axis plots the temperature or color of a star. The highest value of temperature is shown on the left while the lowest is on the right. Each star is plotted as a single point,

White dwarfs are the remnants of stars similar to the Sun after the exhaustion of nuclear fuel. When the nuclear burning nears exhaustion, the star expels majority of its outer layers, creating a planetary nebula. The remaining core could have temperatures of more than 100,000K. Some white dwarfs gather matter from nearby stars via accretion while most others cool down over a timespan of billions of years. Soft X-ray as well as extreme UV observations are a key tools in determining the composition of these stars. [1]

Eris is the most massive and second-largest dwarf planet known in the Solar System. Eris was discovered in January 2005 by a Palomar Observatory-based team led by Mike Brown, and its identity was verified later that year,
