Which type of star best obey mass-luminosity relation?
Main sequence stars
What can electromagnetic spectrum tell us about a star?
Information that you can find about the star by looking at its spectra is its luminosity, surface temperature, its type(common/rare), color, how/if a star is moving, the density, the size, and future of the star. 2. And looking for spectral lines informs as to what elements are present.
What type of star is Alcor?
Alcor is a hot, white A5V main sequence star having a luminosity about 13 times that of the sun. The spectral type implies that Alcor has an effective temperature of 8500 K, a diameter 1.7 times that of the sun, and a mass of about 2.2 solar masses. Alcor is a variable star of Delta Scuti type; see Caph.
What happens when a single high mass star explodes?
you would have a type II supernova
What information does a star's spectrum offer about the star?
Spectroscopy shows what elements are present in the star, it's chemical composition. The different elements give off different energy signatures through radiation, which relate to the wavelength and therefore colour.

What is the color of the Lambda type of star in the Aries constellation?
Lambda Arietis is a double star in the northern constellation of Aries. It is comprised of a yellow-white primary star ( spectral type F, luminosity class V) and a yellow secondary star (spectral type G, luminosity class V). To the naked eye these appears yellow-white.
What is a Subdwarf star?
A star with luminosity class VI under the Yerkes Spectral Classification System. They have luminosity 1.5 to 2 magnitudes lower than main-sequence stars of the same spectral type.
What type of star has a low temperature and low luminosity?

What type of star is the sun classified as?
The sun is a G-type main-sequence star (G V). It may be referred to as a yellow dwarf, or G dwarf star. Alternately it may be called a main-sequence star of spectral type G and luminosity class V.
