Why don’t we see hydrogen Balmer lines in the spectra of stars with temperatures of 3,200 K?
a.
There is no hydrogen in stars this cool.
b.
The stars are hot enough that most of the hydrogen is ionized and the atoms cannot absorb energy.
c.
These stars are so cool that nearly all of the hydrogen atoms are in the ground state.
d.
Stars of this temperature are too cool to produce an absorption spectrum.
e.
Stars of this temperature are too hot to produce an absorption spectrum.
1. The relative velocities of four stars are shown in the figure below with arrows.
If an astronomer were to study the light from these four stars, in which star would the astronomer see greatest redshift of its light spectra? Hint: Think Doppler Effect
A. star 1B. star 2C. star 3D. star 4
Which of the following statements about novae is not true?
A. A nova involves fusion taking place on the surface of a white dwarf.
B. A star system that undergoes a nova may have another nova sometime in the future.
C. Our Sun will probably undergo at least one nova when it becomes a white dwarf about 5 billion years from now.
D. When a star system undergoes a nova, it brightens considerably, but not as much as a star system undergoing a supernova.
Is the answer C? Since the sun has no companion star, it cannot gain accreted matter to initiate a nova and so it would not undergo a nova, it would just undergo a type I supernova?
Thanks!
