It Is Unlikely That Planets near Stars Much More Massive

question 56

Multiple Choice

• A) planets would have to be too close to these cool stars in order to be sufficiently warm for life to evolve,and they would become tidally linked,resulting in no night and day.
• B) there would be no region around the star where UV,visible,and IR light intensities would be suitable for the evolution of life.
• C) no moon would form around a planet near such a star,and a moon is considered essential for the evolution of life because of tidal variations.
• D) these stars would have evolved to red giant or even supernova stages before life could evolve.
