HD 23514, is a star in the Pleiades. It is a main-sequence star of class F6, and has been seen to have hot dust particles orbiting around it. These materials, otherwise known as planetesimals which orbit within a circumstellar disc, are evidence of possible planetary formation.[1]

The star system itself is very young, in the 35~100 million years range,[1] meaning that it is very well likely at the stage of forming planets.

The star will be continuously studied to confirm whether it may be a potential candidate for planetary formation. These studies will be carried out by the Spitzer Space Telescope.[citation needed]
