In which spectral class does a main sequence star with a temperature of 3000 K belong?
class M
Note that most stars in the solar neighborhood lie on the main sequence. The surface temperatures of main-sequence stars range from about 3000 K (spectral class M) to more than 30,000 K (spectral class O).
What is produced during a supernova event?
The final stage in the evolution of a star like our Sun is a neutron star. These stars are produced during a supernova event.
What type of star has 2500 K?
The sun has a surface temperature of 5,500 K, typical for a yellow star. Red stars are cooler than the sun, with surface temperatures of 3,500 K for a bright red star and 2,500 K for a dark red star. The hottest stars are blue, with their surface temperatures falling anywhere between 10,000 K and 50,000 K.
In which spectral class does a main sequence star with a temperature of 3000 Kelvin belong quizlet?
I am a star in the Main Sequence group. I belong in spectral class M with a surface temperature of 3,000 K.
Which star type has a surface temperature of 4000 K and a luminosity 1000 times greater than the Sun?
A white dwarf. When the sun runs out of fuel and can no longer fuse hydrogen in its core, it will start fusing helium and shine with a luminosity of 1000 L☉ but at a temperature of 4000 K.
What elements do supernovae create?
The chemical elements up to iron – carbon, oxygen, neon, silicon and iron – are produced in ordinary stellar neucleosynthesis. The energy and neutrons released in a supernova explosion enable elements heavier than iron, such as Au (gold) and U (Uranium) to form and be expelled into space.
Which stars are produced during a supernova?
Binary stars are two stars that orbit the same point. One of the stars, a carbon-oxygen white dwarf, steals matter from its companion star. Eventually, the white dwarf accumulates too much matter. Having too much matter causes the star to explode, resulting in a supernova.
Which star type has a surface temperature of 4000 K and a luminosity 1000 times greater than the sun?
What is the spectral type of a star with the surface temperature of 5000k?
Stellar Spectral Types
| Temperature | ||
|---|---|---|
| F | 6,000 – 7,500 K | Yellow-white stars |
| G | 5,000 – 6,000 K | Yellow stars (like the Sun) |
| K | 3,500 – 5,000K | Yellow-orange stars |
| M | < 3,500 K | Red stars |
