Step by step
Solved in 3 steps
- A certain star has a temperature twice that of the Sun and a luminosity 64 times greater than the solar value. What is its radius, in solar units?1) What is thermal equilibrium? Is the Sun in thermal equilibrium? How do we know this? 2) In order to maintain thermal equilibrium, how much energy must the Sun generate every second?What is the luminosity of a star having four times the radius of the Sun and a surface temperature of 8,000 K?
- If the sun expanded to a radius 200 times it's present radius, what would the average density be (in g/cm^3?)What percentage of the energy we use comes from the sun? 25% 50% More than 90% Less than 10%The hottest star in the Orion Nebula has a surface temperature of 40,000 K. At what wavelength does it radiate the most energy?
- Fusion only occurs in the solar core. Assuming that 10% of the Sun’s total mass is available to participate in fusion, how long can the Sun continue hydrogen fusion until all available mass is used up? (express your answer in years)Why does nuclear fusion only take place in the Sun’s core?Use Stefan's law to calculate how much energy is emitted per unit area by the photosphere of sun 5800-K.
