HD 23514 (also named Tilottama), 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]

typically a new born star is surrounded by planets because planets form in the protoplanitery disc of gas and dust.These planets go on their merry way not knowing that they are in an orbit of another planet.Billions of years ago two primordial planets orbiting the star hd 23514 spin towards doom.tidal forces make planet from elliptical shape to egg shaped the two planet annihilate each other creating dust and debry seen around the star.
