1.Which type of star is primarily characterized by its low luminosity, high density, and is thought to be at the end of its lifetime?

The spectral class of a star is a short code primarily summarizing the ionization state, giving an objective measure of the photosphere’s temperature. Most stars are currently classified under the Morgan–Keenan (MK) system using the letters O, B, A, F, G, K, and M, a sequence from the hottest (O type) to the coolest (M type).

2.Which type of star is primarily characterized by its low luminosity, high density, and is thought to be at the end of its lifetime?

A red dwarf is the smallest and coolest kind of star on the main sequence.Red dwarfs are by far the most common type of star in the Milky Way, at least in the neighborhood of the Sun, but because of their low luminosity, individual red dwarfs cannot be easily observed.From Earth, not one star that fits the stricter definitions of a red dwarf is visible to the naked eye.

3.Which type of star is primarily characterized by its low luminosity, high density, and is thought to be at the end of its lifetime?

Star – Star – Classification of spectral types: Most stars are grouped into a small number of spectral types. The Henry Draper Catalogue and the Bright Star Catalogue list spectral types from the hottest to the coolest stars (see stellar classification). These types are designated, in order of decreasing temperature, by the letters O, B, A, F, G, K, and M.

4.Which type of star is primarily characterized by its low luminosity, high density, and is thought to be at the end of its lifetime?

For instance, the hottest stars in class A are A0, and then A1, A2, etc all the way to A9, the coolest A type star. This list subsequently shows the main star types using the Morgan–Keenan system. It also provides some quick facts about each type of star, as well as a few details on the physical properties of each class.

5.Which type of star is primarily characterized by its low luminosity, high density, and is thought to be at the end of its lifetime?

If the mass of Star A is less than the mass of Star B, then the main-sequence lifetime of Star A is the main-sequence lifetime of Star B. (a) less than (b) about the same as (c) greater than (d) [There is not enough information given; the lifetime of a star also depends on its spectral cohomology.]

6.Which type of star is primarily characterized by its low luminosity, high density, and is thought to be at the end of its lifetime?

The Sun’s outer atmosphere, which has a high temperature and a low density. Red Giant. A large, cool star of high luminosity. Luminosity. The total amount of radiation that is emitted from a star or other object. White Dwarf.

7.Which type of star is primarily characterized by its low luminosity, high density, and is thought to be at the end of its lifetime?

What property of a star primarily defines its lifetime and stellar evolution? Mass. Which type of nebula has a reddish color? … What will this mean for its luminosity? It has a high luminosity. … the temperature and pressure in the core of the star is not high enough to star thermonuclear fusion.

8.Which type of star is primarily characterized by its low luminosity, high density, and is thought to be at the end of its lifetime?

Stars of low luminosity. … The average star spends ___ of its lifetime on the main sequence. 90%. The CNO Cycle is? … What characteristic of a star primarily determines its location on the main sequence? Mass. As a main sequence star exhausts hydrogen in its core, it next becomes?

9.Which type of star is primarily characterized by its low luminosity, high density, and is thought to be at the end of its lifetime?

The total energy emitted per second by a star is called its luminosity. How bright a star looks from the perspective of Earth is its apparent brightness. The apparent brightness of a star depends on both its luminosity and its distance from Earth. Thus, the determination of apparent brightness and measurement of the distance to a star provide …

10.Which type of star is primarily characterized by its low luminosity, high density, and is thought to be at the end of its lifetime?

The main sequence lifetime of a star is related to its mass by: 1/M^3 Perhaps the greatest of the Greek astronomers, ___ compiled the first catalog of stars, accurately measured their positions, and defined the basic system of stellar brightness
