How are millisecond pulsars formed? The leading theory for the origin of millisecond pulsars is that they are old, rapidly rotating neutron stars that have been spun up or “recycled” through accretion of matter from a companion star in a close...
How do you determine the age of open star clusters? By determining the mass of the main-sequence turnoff stars, we get the age of the cluster. The cluster age equals the main-sequence lifetime of the turnoff stars. This is one of...
What happens to stars in globular clusters? While you can see multiple generations of stars in globular clusters, what happens is the subsequent generations evolve from the first one. The first set of stars gobble up most of the gas, then...
Does color determine age of star? Since stars are powered by nuclear fusion at their core, they maintain a steady dynamic equilibrium throughout their life and display their life cycle position using color. Due to this uniform time and color cycle,...
How do you determine the age of a star in a cluster? By placing the stars in a globular cluster on a Hertzprung-Russell diagram, astronomers can determine the cluster’s age by looking at the main sequence turnoff point and comparing it...
How do u determine the age of a star? “It is impossible to determine the age of a single star all by itself. The only real means we have to determine stellar ages is through the study of star clusters. In...
How do you calculate the age of a star? “It is impossible to determine the age of a single star all by itself. The only real means we have to determine stellar ages is through the study of star clusters. What...
What does a color-magnitude diagram tell us? A color-magnitude diagram is a scattergraph of astronomical objects showing the relationship between each object’s absolute magnitude and its estimated surface temperature or between optical or perceptual proxies for these quantities. How do you...
What is the maximum age of a star? Most stars are between 1 billion and 10 billion years old. Some stars may even be close to 13.8 billion years old—the observed age of the universe. The oldest star yet discovered, HD...
What will the HR diagram of a newly formed star cluster look like? A very young cluster will have a HR diagram with a cluster of T-Tauri stars evolving towards the main sequence. As time passes the most massive stars at...
