QUESTION 10
Which of the following Cepheid variable stars would appear to be the brightest from Earth?
A Cepheid variable star that is 10,000 times as luminous as the sun.
A Cepheid variable star with a period of 10 days.
A Cepheid variable star with a period of 3 days.
There is not enough information given.
"51 Pegasi" is the name of the first normal star (besides the Sun) around which a planet was discovered. It is in the constellation Pegasus the horse. Its parallax is measured to be 0.064 arcsec.
a. What is its distance from us?
b. The apparent brightness is 1.79 × 10-10 J/(s·m2 ). What is the luminosity? How does that compare with that of the Sun? Look up the temperature: how do
A star has a parallax angle of 0.0270 arcseconds and an apparent magnitude of 4.641. What is the distance to this star? [Answer in parsecs]
What is the absolute magnitude of this star?
Is this star more or less luminous than the Sun? Answer "M" for More luminous or "L" for Less luminous. (HINT: the absolute magnitude of the Sun is 4.8)
What is the luminosity of this star? (HINT: The luminosity of the Sun is 3.85×1026 W.)
