This exam is entirely multiple choice or true/false. A=T, B=F TRUE/FALSE. Write 'T' if the statement is true and 'F' if the statement is false. 1) The photosphere is about 100 times the diameter of the Earth, and large sunspots are larger than our whole planet. 1) 2) Granulation is the most obvious proof of solar convective energy transport. 2) 3) The solar corona is much cooler than the Sun's surface, hence we must wait for a total solar eclipse to glimpse it with the naked eye. 3)...

A large luminosity star - Emits more light than a low luminosity star If a red giant appears the same brightness as a red main sequence star, which one is further away? - The red giant The heaviest nuclei of all are formed - During a supernova explosion Hydrogen-2 + proton = ? - Hydrogen-2 + proton = Helium-3 Why does the main sequence part of a star's life end? - The hydrogen in the core is exhausted Many of the brightest 100 stars viewed from Earth are not on the main sequence (even tho...
