SBCC KELLY ERTH 101 EXAM 3 Questions and
Correct Answers | Latest Update
A high-mass protostar is more luminous than a low-mass protostar
because it:
Ans: has a higher temperature because the original cloud had more
gravitational potential energy.
Why does stellar fusion of massive stars end with an iron core?
Assignment Expert
Ans: Iron does not release energy when it undergoes fusion.
The Sun produces energy in the core primarily through:
Guru01 - Stuvia
Ans: the proton-proton chain (P-P chain)
Gravitational waves are:
2026
Ans: ripples in the fabric of space-time.
Imagine that a spaceship is traveling away from the Earth at half the

speed of light relative to the Earth. The spaceship shoots a laser in
the same direction it is moving. How fast is the laser light traveling
relative to the Earth?
Ans: The speed of light.
Originally, Annie Cannon and the Harvard Computers organized the
stars by an alphabetical spectral class (A,B,C,D,E,F...). They realized
that spectral class is connected to surface temperature. Which of the
following correctly orders the spectral types of stars from hottest to

coolest?
Ans: OBAFGKM
The general theory of relativity includes an explanation of:
Ans: Gravity and space-time
These small but hot stellar remnants are the collapsed cores of stars
and are found in the lower left of the H-R diagram. Gravity is
prevented from making them smaller by their electron degeneracy

pressure.
Guru01 - Stuvia
Ans: white dwarf.
an astronomer observes a globular cluster of stars and
constructs an HR diagram like the figure below. What
2026
can he or she learn by identifying the spectral class of

the region marked "X"?
Ans: the age of the cluster.
The sun's magnetic cycle has a period of
Ans: 22 years
The figure below shows the trajectories of particles
produced within the core of the Sun. What kind of
particle follows the trajectory labeled "X"?
Ans: neutrinos.
