... 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. ...

My research efforts have focused on three areas which are: . More than 200 extrasolar planets have been discovered around relatively nearby stars, primarily through the Doppler line shifts owing to the reflex motions of their host stars, and more recently through transits of some planets across the face of the host stars. ... Gravitational microlensing provides a novel technique to look for planets around lens stars, and this is the only technique currently capable of detecting Earth-mass planets. ...

Having studied the solar corona and its radio emissions sunspot cycles ago, I was keen to verify its existence optically during the total solar eclipse of Wednesday, 4 December 2002, the first on Australian soil since 1976. The moon's shadow was to travel from the south-Atlantic west of The Congo, across southern Africa, the Indian Ocean and into the Great Australian Bight, finally making Australian landfall at Ceduna, South Australia (SA). ... The favoured site to observe the eclipse was Ceduna. ...
