... GSAOI Home . ... Science . ... Deep imaging at J , H , and K is required to identify all stellar objects, brown dwarfs, and planetary mass objects in the central region of the Orion Nebula Cluster down to masses comparable to that of Jupiter. This is required to establish the initial mass function, i.e., the number of stars of each mass that have formed, in this region of intense massive star formation. ... The fields of the GSAOI detectors are shown as four green squares in each frame. ...

3) Planets and Brown Dwarfs . ... By its nature, this method is most sensitive to massive planets orbiting close to their stars. ... That means that some of the more massive extrasolar planets could actually be brown dwarfs (although the statistics of the finds suggest that most of them are not). ... Another possible difference between brown dwarfs and massive planets is how they are born. ... They would base the fundamental definition on the mode of formation: a planet is built from planetesimals. ...

Building a new cycle LRP has a number of phases, some of which are iterative. The general idea that has been used in Cycles 7, 8 and 9 (at least) is to build an LRP based upon the existent dynamic LRP all at once (as opposed to letting visits dribble into the plan as they become ready for long range planning). ... What follows is an outline of a series of steps and actions that need to be taken as a part of the new Cycle planning process. ... In Cycle 10, other issues will raise their head: . ...

The Sun is our nearest star and the source of energy for life on Earth. ... For centuries astronomers wondered whether they were clouds floating in the Sun's atmosphere, but we now know that they really are huge regions of magnetic field, about as intense as the field at the poles of an iron magnet. ... Such abrupt events were named solar flares , and what made them especially interesting was that occasionally, after a prominent flare, a magnetic storm would erupt on Earth. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

Next: J.G. Doyle, Research Astronomer Up: Research Previous: C.J. Butler, Research Astronomer Contents . Dr John Chambers has made detailed computer simulations of the origin and formation of the Earth and the inner planets. These build upon earlier work by Chambers and George Wetherill, of the Carnegie Institution of Washington, whose computer calculations had predicted that planets would tend to have elliptical orbits rather than the almost-circular ones we see in the Solar System. ...
