What spectral class in the sun?
The Sun is a as a G2V type star, a yellow dwarf and a main sequence star. Stars are classified by their spectra(the elements that they absorb) and their temperature. There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M
Why is the spectral sequence of stars not alphabetical?
The spectral sequence of stars is not alphabetical because it is based on the temperature of the star, with O-type stars being the hottest and M-type stars being the coolest. The sequence was originally arranged in this manner by Annie Jump Cannon, a pioneering astronomer, in order to classify stars based on their spectral features.
What information is needed to plot a star on the H-R diagram?
To plot a star on the H-R diagram, you need the star's luminosity (or absolute magnitude) and its surface temperature (or spectral type). These two properties allow you to place the star accurately on the diagram based on its position relative to other stars.
How would you arrange this in order red giant white dwarf and main sequence?
The correct order of these stellar evolutionary stages is main sequence, red giant, white dwarf. A star begins its life on the main sequence where it fuses hydrogen into helium. As it runs out of fuel, it expands into a red giant before shedding its outer layers and collapsing into a white dwarf.
Why does the rainbow arranged in roygbiv?
That's the sequence of the colors of light in order from longest to shortest wavelengths.

What is the most commonly used mnemonic for spectral classification?
The most commonly used mnemonic for spectral classification is "Oh Be A Fine Girl/Guy, Kiss Me," which helps remember the sequence of spectral types: O, B, A, F, G, K, M. Each letter represents a class of stars, ordered by decreasing temperature and increasing wavelength. This mnemonic is particularly helpful for astronomy students and enthusiasts in recalling the order of stellar classifications.

What happens to volume when temperature of gas is decresd at constant pressure?
If the temperature of the gas is decreasing, then in order to maintain constant pressure, you would have to compress it in volume.
What are the colors of visible light in order of decreasing frequency.?
The colors of visible light, in order of decreasing frequency, are violet, indigo, blue, green, yellow, orange, and red. Violet has the highest frequency, while red has the lowest. This sequence represents the visible spectrum, which is part of the electromagnetic spectrum.
Is spectral class B in space hot or cold?
Spectral class is the categorization of stars by temperature and size, mostly the former. Spectral class B is very hot. In descending order (hottest to coolest) the spectral classes are O,B,A,F,G,K,M. You can see that B is very near the top.
Type of stars in the H-R diagram?
The HR diagram has the star's temperature along the horizontal axis and the absolute magnitude (brightness) along the vertical axis. Each star is represented by a single dot. Higher temperature is usually associated with more brightness so many stars lie on or near a line on the diagram called the Main Sequence. Red giant stars are found on the upper right hand quarter because they are relatively cool but still very bright.
What is the ranking of radicals in order of decreasing stability?
The ranking of radicals in order of decreasing stability is as follows: benzyl allyl tertiary secondary primary methyl.
What is Function to sort the given employee numbers in decreasing order.?
ORDER BY
What is the denotation of sequence?
the denotation of sequence is put in order
Why does main sequence has a limit at the lower end?
The reason main sequence has a limit at the lower end is because of temperature and pressure. The lower limit exists in order to exclude stellar objects that are not able to sustain hydrogen fusion.
The order in which the actions occur is known as sequence of what?
Sequence of Events.
