1. Variable Star

   Variable Star is a 2006 science fiction novel by American author Spider Robinson, based on the surviving seven pages of an eight-page 1955 novel outline by the late Robert A. Heinlein († 1988). The book is set in a divergent offshoot of Heinlein's Future History and contains many references to works by Heinlein and other authors. It describes the coming of age of a young musician who signs on to the crew of a starship as a way of escaping from a failed romance. Robinson posted a note on his website in 2009 noting that his agent had sold a trilogy of sequels based on the novel and its characters.

1. variable star

   A variable star is a star that changes in brightness over time due to intrinsic changes within the star itself or due to external factors such as eclipsing binary systems. The changes can occur over periods ranging from seconds to years, and the variation in brightness can be slight or dramatic.

1. Variable star

   A variable star is a star whose brightness as seen from Earth fluctuates. This variation may be caused by a change in emitted light or by something partly blocking the light, so variable stars are classified as either: ⁕Intrinsic variables, whose luminosity actually changes; for example, because the star periodically swells and shrinks. ⁕Extrinsic variables, whose apparent changes in brightness are due to changes in the amount of their light that can reach Earth; for example, because the star has an orbiting companion that sometimes eclipses it. Many, possibly most, stars have at least some variation in luminosity: the energy output of our Sun, for example, varies by about 0.1% over an 11 year solar cycle.
