- WARPED DISK MAY INDICATE PRESENCE OF PLANET
- AROUND THE STAR BETA PICTORIS
-
- This image from NASA's Hubble Space Telescope shows for the first time
- the inner region of a 200-billion mile diameter dust disk around the
- star Beta Pictoris. This region has long been hidden from
- ground-based telescopes because of the glare from the central star.
- The disk is slightly warped. If the warp were there when the star
- formed, it would long since have flattened out, unless it is produced
- and maintained by the gravitational pull of a planet. The suspected
- planet would dwell inside a five-billion mile diameter clear zone
- inside the inner edge of the disk.

- This is a visible light image of the disk, which appears spindle-like
- because it is tilted nearly edge-on to our view. The disk is made up
- of microscopic dust grains of ices and silicate particles, and shines
- by reflected light from the star. This image indicates that the
- central clearing is occupied by one or more planets which agglomerated
- out of the disk and then swept out smaller particles. The bright star,
- which lies at the center of the disk, is blocked out in this image.

- False-color is applied through image processing to accentuate details
- in the disk structure. Hubble reveals that the pink-white inner edge of
- the disk is slightly tilted from the plane of the outer disk
- (red-yellow-green) as identified by a dotted line. A simple explanation
- is that a large planet is pulling on the disk. It is not possible to
- see the planet directly because it is close to the star, and perhaps a
- billion-times fainter.
-
- This image was taken with the Wide Field Planetary Camera 2 in January
- 1995. The star is located 50 light-years away in the southern
- constellation Pictor (Painter's Easel). Beta Pictoris is a main
- sequence star, slightly hotter than our Sun.
