The star Sirius A emits a black body spectrum that peaks at Epeak = 2.82kBT = 2.4 eV and its total power output is 24 times more than the Sun.
a) What is the temperature of Sirius A?
b) Use Stefan’s Law to estimate the radius of Sirius A as compared to the Sun.
You will need to know that Tsun = 6000 K.
c) How much hotter would the Earth be if it orbited Sirius A rather than the Sun?
Assume that the Earth-Sirius A distance is the same as the Earth-Sun distance. Also,
assume Earth is a black body.

Blackbody Spectrum Question
(a) Examination of the spectrum of a star shows
that it is brightest at the frequency 1.5 × 10^14 Hz. What is its
temperature? How does this compare to the Sun’s temperature? What
color will this star appear to be?
(b) How does the surface brightness of this
star compare with Sun’s surface brightness, according to the
Stefan-Boltzmann law?
(c) Somewhat surprisingly, the star in question
appears extremely bright, much brighter than the Sun would appear
at...

You are on an interstellar mission from the Earth to the 8.7
light-years distant star Sirius. Your spaceship can travel with 70%
the speed of light and has a cylindrical shape with a diameter of 6
m at the front surface and a length of 25 m. You have to cross the
interstellar medium with an approximated density of 1 hydrogen
atom/m3 . (a) Calculate the time it takes your spaceship to reach
Sirius. (b) Determine the mass of interstellar...

Explain why the first observed rising of the bright star Sirius
in the sky just before dawn happens at the same time each year. How
did ancient Egyptians take advantage of this?

An exoplanet is discovered through careful Doppler shift
analysis of the spectrum of the star it is orbiting. The
star’s spectrum allows us to conclude with some confidence that the
star has a mass M = 0.60 solar masses, and a luminosity L = 0.13 of
the solar luminosity. Assuming the orbits are circular and observed
edge-on, the Doppler shift tells us that the star has a
speed about the centre-of-mass of V = 250 m/s and the period of...

In fruit flies, a grey body is dominant to a black body, and
normal wings are dominant to vestigial wings. Flies are
heterozygous for both grey bodies and normal wings were crossed
with flies that had black bodies and vestigial wings. The following
results were obtained:
Phenotype
Number of flies
Grey body/Normal wings
482
Black body/Vestigial wings
472
Grey body/Vestigial wings
103
Black body/Normal wings
92
The results indicate that the genes for wings and body color are
on the...

1. The first set of data you receive is a spectrum of a main
sequence star taken with the MacDonald Spectrometer onboard HST.
Based on the fact that the star’s spectrum has strong Hydrgen
absorption lines and many molecular absorption lines, what spectral
type do you believe this star to be? Explain.
2. Based on this star’s spectral type, explain the evolutionary
stages that it will go through after it completes the main sequence
phase of its life. How will...

I will not see any of these types of spectra.
A bright line emission spectrum.
A continuous spectrum.
