What is the main sequence turning off point for a star cluster?
The main sequence turn-off age tells how old the cluster. The mass of a star determines its luminosity, temperature, size and how quickly it will evolve from the main sequence. It is fortunate that stars with the same mass will develop at the same speed.
How many globular clusters are there in the Milky Way?
150 globular clusters
Where are globular clusters found in the Milky Way?
Globular clusters of star stars are located mainly in the Great Spherical Halo of the Milky Way. Spiral galaxies such as our Milky Way have stars, gas, and dust. They are mostly composed of stars, gas, and dust. However, the flat disk that contains the spiral arms has been enriched with a rounded bulge, halo, and centering on the galaxy’s centre.
How are blue stars possible in globular clusters?
The most probable explanation is that blue stars collide when they are too close to other stars or similar mass objects. This newly formed star is therefore of higher mass and would have a place on the HR diagram that would be populated with young stars.
What is the difference between type I and type II supernovae?
A type I supernova is a closed binary system in which two average stars orbit each other very closely. One star will become a red giant when it exhausts all of its hydrogen and then fall into a white dwarf. A type II supernova occurs in larger stars of around 10 solar masses.
What type of waves were used to study the foggy Milky Way?
It is currently “gobbling up” two small galaxies. What waves were used for studying the “foggy Milky Way”? Because radio waves and infrared wavelengths can travel through the Milky Way dust and reach telescopes on Earth, they were used for studying the “foggy Milky Way”.
What is in the middle of the Milky Way?
The Galactic Center, or Galactic Centre, is the rotational centre of the Milky Way galaxy. It is a supermassive dark hole of 4. 100 +- 0. 034 million solar masses, which powers the compact radio source Sagittarius A*.
What phrase best defines a star system?
What phrase best describes a star system’s characteristics? Stars are brighter.
Where is the nearest galaxy to the Milky Way?
The Andromeda Galaxy
