Explain how astronomers might use spectroscopy to determine the composition and temperature of a star (3 points) elemental abundances, temperature, rate of rotation, presence of turbulence, strength of magnetic field, and atmospheric pressure. In april, 2005 a more precise measure of the celestial body allowed to determine a complete rotation speed about 10 hours at the time of its discovery, sedna was the biggest object discovered in the solar system since the discovery of pluto. Astronomers usually cannot tell the age of an individual star there are certain stars that we know are very young, and others that are very old, but for most stars we cannot tell.

Key points: basic parameters of stars - luminosity, temperature, size, mass, composition - and how they are determined the sun is a star in general, a star is an object making its own energy and that is (or was) capable of sufficiently high central temperature and pressure that nuclear reactions can occur. Prepare a 1,000 – 1,250 word paper in which you discuss the science of sunlight and stars include the following elements: explain how astronomers determine composition, temperature, speed, and rotation rate of distant objects. Explain how astronomers determine composition, temperature, speed, and rotation rate of distant objects o explain the properties of stars in the h-r diagram located in ch 15, “what is a hertzsprung-russell diagram” of the cosmic perspective o summarize the complete lifecycle of the sun.

Spectroscopy, chemistry, physics, astronomy, spectroscope, composition of stars, chemical composition, spectrum such as the surface temperature, age, speed of rotation, strength of magnetic field, and the speed of the star towards the earth or away from the earth scientists can determine the speed of rotation of the star the velocity. Determine the time of moonrise and, if possible, the distance between earth and the moon on the particular date of viewing the north star (polaris): the associated constellations of ursa minor and ursa major (also known as the little dipper and the big dipper. How do we determine what distant planets, stars etc are made of when trying to give a quick explanation to some friends who ridiculed the idea astronomers can know for certain what composition a distant object has spectroscopy and the current state of our ability to determine the composition of extra-solar planets related 15 how. Explain how astronomical instruments help astronomers determine the composition, temperature, speed, and rotation rate of distant objects explain the properties of stars in the diagram located in the “what is a hertzsprung-russell diagram” in ch 11 of the essential cosmic perspective. Clearly explain how studying an object's spectrum can allow us to determine each of the following properties of the object a the object's surface chemical composition the speed at which the object is moving towards or away from us g the object's rotation rate the object's rotation rate 6 suppose that all the energy.

These measurements of light enable astronomers to determine certain physical characteristics of objects, such as their temperature, composition, and velocity the temperature of an object is related to the wavelength at which the object gives out the most light. Just recently, astronomers discovered a distant solar system, 127 light years away with up to seven planets orbiting a sun-like star called hd 10180 like the very first exoplanet 51-pegusus. Include the following elements: • explain how astronomers determine composition, temperature, speed, and rotation rate of distant objects • explain the properties of stars in the h-r diagram located in ch 15, “what is a hertzsprung-russell diagram” of the cosmic perspective. Determine the rotation rate of our sun by watching sunspots move from one side to the other it should be close to 26 days this is how galileo determined the solar rotation rate in 1610. A relationship between the temperature of a blackbody and the rate at which it radiates energy term ultraviolet radiation: the plane in which a lens or mirror forms an image of a distant object term focal point: astronomers can determine whether that star is a main- sequence star, giant, super-giant, or white dwarf.

Information from astronomical spectra the key point to remember about astronomical spectra is that they provide astronomers with a wealth of detail about the physical characteristics, motion and composition of objects. Astronomers can measure these shifts to determine how fast the star is moving and calculate the mass of the planet that must be tugging on it this is currently by far the most successful and widely used method for discovering extrasolar planets. Determine where the sun is in its lifecycle question prepare a 1,000 – 1,250 word paper in which you discuss the science of sunlight and stars include the following elements: explain how astronomers determine composition, temperature, speed, and rotation rate of distant objects o explain the properties of stars in the h-r diagram located. It is one of the most useful devices in astronomy, because it allows astronomers to determine the chemical composition of planets and stars, as well as to indicate the speed and direction of a star or galaxy.

  • Explain how astronomers can measure the motion and rotation of a star using the doppler effect \n stellar spectra can also be used to determine the chemical composition of stars hydrogen and helium make up most of the mass of all stars the total (three-dimensional) speed and direction with which an object is moving through space.
  • For example, astronomers could use it to determine the rotation of distant planets, he says back on earth, he adds, lasers could be sent through wind farms to determine the rotation of air currents.

Please check all question included in this tutorial below sci 151 final exam guide set 1 1 the sun, moon, and the planets follow an imaginary line through the sky called the ecliptic the reason for the ecliptic is that 2 the star betelgeuse is classified as aredsupergianttypestar this star is. A proper astronomer here will explain this better but it is to do with light the light emitted from stars has a particular colour, and here on earth it was noted that temperatures have colours. Question explain how astronomers determine composition, temperature, speed, and rotation rate of distant objects o explain the properties of stars in the h-r diagram located in ch 15, “what is a hertzsprung-russell diagram†of the cosmic perspective.
