Which of These Statements About the Capability of an O-Type

question 142

Multiple Choice

Which of these statements about the capability of an O-type star to trigger the formation of other stars is NOT correct?

• A) O-type stars are massive. When they form stellar nebulae, as the Sun did, small stars form instead of planets.
• B) The H II region surrounding an O-type star expands into the giant molecular cloud, producing a shock wave that can compress the un-ionized material and cause it to collapse.
• C) O-type stars are massive and thus have short lifetimes. After an O-type star erupts in a supernova, the material it ejects into space can eventually condense to form a new generation of stars.
• D) The shock wave produced when an O-type star forms a supernova can compress the interstellar medium and cause it to collapse.
