Putting it all Together

Each of the tasks (A-F) below is needed to determine the distance to a supernova:

A. Determine the peak apparent magnitude from the model light curve.

B. Measure the 𝚫m15 of the model light curve.

C. Insert the values for peak apparent and absolute magnitudes into the distance modulus equation to calculate the distance to the supernova.

D. Analyze the apparent magnitude data in a light curve to ensure the data represents a Type Ia supernova.

E. Use the 𝚫m15 from the model curve to determine the peak absolute magnitude.

F. Fit a model light curve to the data, paying particular attention to fit the part of the light curve from the peak to 15 days after the peak.

Questions

  1. Different types of stars can explode to form supernovae. A star that is more than 8 times the mass of the Sun forms a Type
    supernova. A Type
    supernova forms from a
    in a binary star system.
  2. Type Ia supernovae achieve an intrinsic peak brightness that is
    than the intrinsic peak brightness of Type IIp supernovae. After reaching its peak brightness, the light output from a Type Ia supernova
    for a few months.
  3. Type
    supernovae cannot be used for distance measurement because the stars that become this type of supernova have a range of
