Exoplanetary Scratchpad

[SysBP Img]

The first found planetary system that originated from another galaxy and lies 2000 ly away in the constellation Fornax. The star is slightly less massive than the sun and is near the end of its life. It has already passed through the Red Giant phase, but may soon envelope its epistellar giant planet during its next expansion. This is the only star at such a stage known to have a planet and may have swallowed smaller planets. Planet b must have originated further away from the star in order to have survived the Red Giant phase of the star and was then pulled inward to its present location. The star is from the Helmi stream, which is a remnant of a dwarf galaxy enveloped by the Milky Way 6 to 9 Billion years ago. It is the first planet discovered around a star that is both very old and very metal poor, the poorest star known so far with a planet, showing that planets could form around such stars, probably due to gravitational collapse rather than core accretion. It may be made completely of Hydrogen and Helium with no core. It was discovered just prior to the 500th exoplanet.
