5. ASP: A Good Definition of the Word "Planet": Mission Impossible?
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. ...

... Solar System . Star Clusters . ... Stars@ESO . ... Observations with the Very Large Telescope Interferometer (VLTI) at the ESO Paranal Observatory (Chile) have provided the first-ever direct determination of the angular sizes of the disks of the solar-type stars Alpha Centauri A and Alpha Centauri B.

... Files in red?history) . ... The Sun . ... Large sunspots may be occasionally seen by the unaided eye, with the sun near the horizon and dimmed by thick haze. ... Year after year, beginning in 1826, on every clear day, Schwabe would scan the sun and record its spots, until 17 years later he began to suspect a regular variation . ... Some, led by Rudolf Wolf, examined old records to reconstruct earlier sunspot cycles, while Edward Sabine in England in 1852 found a similar periodicity in magnetic...

14. http://zebu.uoregon.edu/51peg.html
... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ... Recall that the measurements of radial velocity only yield v sin i which in turn gives us M sin i. For most values of i, sin i will be greater than 0.5 and this gives a mass estimate of 0.5 Jupiter masses. ...

15. What is a pulsar?
Pulsars (from PULSAting stARs) were discovered, albeit accidentally, by Jocelyn Bell at Cambridge in 1967. ... In addition, some pulsars are known to be members of binary systems in which the companion is another neutron star, a white dwarf and even a main sequence star. ... PSR B1913+16: . ... Although subsequent pulsar surveys with better sensitivity to short period objects have found a large number of similar objects, for 24 years PSR B1937+21 stayed as the most rapidly rotating neutron star known. ...
