Similar Star Systems
Binary star systems are common, found more frequently than single star systems like our own. The arrangement of HD 113766, a binary star system with a protoplanetary disk around one star, is somewhat similar to the one-half of the system HD 98800, which has been reported to have a large amount of warm dust mass at the equivalent distance of the solar system's asteroid belt. It is not currently known why both of these star systems should have such configurations; i.e. a protoplanetary disk around part of the system while other stars in the system lack one.

Famous quotes containing the words similar, star and/or systems:
“We cannot feel strongly toward the totally unlike because it is unimaginable, unrealizable; nor yet toward the wholly like because it is stale—identity must always be dull company. The power of other natures over us lies in a stimulating difference which causes excitement and opens communication, in ideas similar to our own but not identical, in states of mind attainable but not actual.”
—Charles Horton Cooley (1864–1929)
“Fear not: that ultimate Star is frail,
only a flake of snow,
whirled in His breath.”
—Hilda Doolittle (1886–1961)
“The only people who treasure systems are those whom the whole truth evades, who want to catch it by the tail. A system is just like truth’s tail, but the truth is like a lizard. It will leave the tail in your hand and escape; it knows that it will soon grow another tail.”
—Ivan Sergeevich Turgenev (1818–1883)
