HW 10

A  the coronal mass ejections interfere with the photons, adding too much noise to the spectrum.

B  the Sun is too hot to radiate at all wavelengths.

C  the relatively cool outer layers absorb photons emitted in the hot inner parts of the Sun, producing absorption lines.

D  its spectrum consists of emission lines of the elements in the Sun, so there are some gaps.

E  its core is much hotter than its surface, so the shape of the curve is distored.

A  solar prominences

B  the Sun’s blackbody spectrum

C  prominences and filaments

D  solar flares

E  sunspots

A  nuclear explosions

B  granulation oscillations

C  the Zeeman effect and the Maunder minimum

D  differential rotation, winding up the magnetic fields

E  a constant dipole magnetic field

A  they are regions in which strong magnetic fields make it difficult for fresh supplies of hot, ionized gas to reach the photosphere.

B  they are patches of the photosphere that occasionally burn up, creating soot.

C  the changing magnetic polarity of the Sun causes gas in the sunspot to cool down substantially.

D  they are holes in the photosphere through with cooler interior of the Sun is visible.

E  they are much hotter than the surrounding area, so their emission peaks at ultraviolet wavelengths, which our eyes cannot see.
