3) The emission spetrum from stars can be used to determine their temperature ( they are blackbody emitters). our sun has a temperature of 5800 k.

a) use the wavelenght maximum equation to determine the wavelenght maximum for the sun ( in nanometers).

b) The star Bellatrix (in the orion constellation)has a temperature of 27,000k.

What is the wavelenght corresponding to the maximum intensity of the emisson from Bellatrix?

Expert Solution

Wavelength of max emission (um) = 2897 umK / Temperature

a) Wavelength of max emission (um) = 2897umK / 5800

= 0.4995 um

b) Wavelength of max emission (um) = 2897umK / 27000

= 0.1073 um

a. Variable stars can be used to estimate the distance to astronomical objects which contain them. If there is a signiﬁcant amount of dust in the line of sight, these stars will appear fainter in the optical than what really are. What would happen to the distance estimate if one does not correct for the presence of dust extinction? Explain qualitatively. b. Do weak encounters signiﬁcantly aﬀect the trajectory of a star in a galaxy? c. Two astronomical sources have exactly...
