The three different types of spectrums.
What are the continuous spectrum, the dark-line spectrum, and the bright-line spectrum?
100
Whenever ther are sun-sized stars or smaller: A proton-proton chain reaction occurs (hydrogen burning). 4H fuses to become 1 He Then, the energy produced in the core moves to the surface as photons.
What is Nuclear Fusion?
100
The hotter the star, the bluer it is. Ex: Rigel Blue and temp=30,000K
What is the comparison of temperature and color of a star?
100
How much an ellipse varies. e= cf ________ a
What is eccentricity?
100
An optical instrument for making distant objects appear larger and therefore nearer.
What is a telescope?
200
A shift in the location of the spectral lines due to the changing distance between the observer and the object.
What is the doppler effect?
200
What is the sun's size compared to the earth's size?
Although considered ans "average sized" yellow dwarf, it is 10x larger than Earth.
200
-The/intrinsic brightness of a star. -Scientists mathematically adjust all of the stellar data and "pretend" all the stars are the same distance away.
What is absolute mangitude?
200
1)The orbit of each planet is an ellipse with the sun at one focus point. 2)A line drawn from a planet to the sun sweeps out equal areas in equal time. 3)The square of the orbital period of a planet is directly proportional to the cube of its distance.
What are the laws of Planetary motion?
200
An optical device for producing and observing a spectrum of light or radiation from any source, consisting essentially of a slit through which the radiation passes, a collimating lens, and an Amici prism.
What is a spectroscope? Definition from Dictionary.com
300
Related to the Doppler effect: The shift away (distance increases) Shift towards longer wavelength.
What is the Red Shift. Keep in mind there is also the Blue shift, which is where the shift is towards(distance decreases) and the shift is toward shorter wavelengths.
300
-Follows and 11 year cycle -produced by magnetic field disturbances in the photosphere
What are sun spots?
300
1)Nebula or Nebulae 2)Protostar 3)Stable state or Main Sequence Star 4)Red Giant or Super Giant Stage 5a)Planetary Nebula or 5b)Supernova 6a)White Dwarf or 6b)Newtron star or a black hole
What is the life of a star?
300
When a planet is closest to the sun.
What is perhelion?
300
Produced by: -Stars: When light from the core passes through the star's atmosphere -Planet's atmospheres -Cool gases absorb certain wavelengths of light, leaving dark lines where those wavelengths would appear Also known as the Absorption Spectrum
What is the Dark-Line Spectrum?
400
If the doppler shift is large, then the speed of relative distance change is greater.
What is the relationship between the doppler shift and the speed that the relative distance is changing?
400
The brightness of a star as it appears from earth. Controlled By: -Distance -Temp -Size
What is apparent magnitude?
400
A star stays in this stage for 90% of its life.
What is the amount of time spent in the Main Sequence (or stablle state)? or What is a main sequence star?
400
When a planet is farthes away from the sun.
What is aphelion?
400
-Gathering facts from the observations -formulate scientfic hypotheses
What is the process of scientific method?
500
-Temperature/color -Composition -Relative Speed(toward or away) -Relative distance -Mass
What can we deduce about a star by looking at its spectrum?
500
The apparent shift in position of a star due to the Earth's movement around the sun.
What is stellar parallax?
500
Gravitation field so strong that light cannot escape.
What is a black hole?
500
What does the Harmonics law mean?
It is the third law of planetary motion that menas that the farther in orbit a planet is from the sun, the longer it takes to complete an orbit.
500
If eccentricity = 0, the ellipse will be a ______.
A circle.
