With respect to size and mass, the Sun is approximately in the percentile 85 or 90 - meaning that 85-90% of stars are smaller and less massive than the Sun. So, most stars are smaller, less massive (and therefore less luminous) than our Sun, but there are still quite a lot that are larger - and in many cases, MUCH larger.The total lifetime of our Sun is estimated to be about 10 billion years; for comparison, the most massive stars have a lifetime of only a few million years, while the smallest red dwarves can have a lifetime of several trillion years.

Why do the brightest stars in your sky appear so bright compared to other stars in your sky?

The brightest stars appear brighter because they are closer to Earth or intrinsically brighter due to their size, temperature, or luminosity compared to other stars. Their brightness makes them stand out more in the night sky.


How are stars on the upper left end of the main sequence different from those on the lower right end?

The main sequence is a map of star brightness against their temperature. Stars that lie on the main sequence in the top left are the high mass stars. Cooler, smaller stars lie near the line at the lower right.


What characteristic of a star is determined by its distance from the observer?

The apparent brightness of a star is determined by its distance from the observer. Stars that are closer appear brighter in the sky, while those that are farther away appear dimmer. This relationship follows the inverse square law, meaning that a star's brightness decreases with distance squared.


What is the significance of the flux formula in astronomy and how is it used to measure the brightness of celestial objects?

The flux formula in astronomy is significant because it helps astronomers measure the brightness of celestial objects. Flux is the amount of energy received per unit area per unit time from a celestial object. By using the flux formula, astronomers can calculate the amount of light or radiation emitted by a celestial object and compare its brightness to other objects in the sky. This measurement is crucial for understanding the properties and behavior of celestial objects, such as stars, galaxies, and other astronomical phenomena.


What factors should be considered when comparing two stars of the same spectral type and subtype?

When comparing two stars of the same spectral type and subtype, factors to consider include their luminosity, temperature, size, age, and composition. These characteristics can provide insights into the stars' evolutionary stage, potential habitability, and overall behavior.

Looking at the H-R diagram what 2 factors determine the brightness of a star?

The H-R diagram graphs total brightness versus surface temperature (related to color); by itself, it doesn't tell you where those two things come from.The brightness of a star depends on its mass, and on where it is in its development history.


How would you compare the brightness of the bulbs as you increase the number of bulbs?

-- If the bulbs are in parallel, then the addition of a bulb has no effect on the brightness of those that were there before. -- If the bulbs are in series, then the addition of a bulb causes the brightness of those that were there before to decrease. (And I wasn't even there when you did the experiment !)

Which star is giving off more light?

The star that gives off more light is likely larger and hotter than the other star. The brightness of a star is directly related to its size and temperature, with larger and hotter stars emitting more light.
