Gravitational microlensing by low-mass objects in the globular cluster M22
Article Abstract:
Research is presented concerning the use of gravitational microlensing to investigate the mass of stars and planets in the globular cluster M22. The amount of dark baryonic matter in the early stages of star formation is discussed.

Transiting extrasolar planetary candidates in the Galactic bulge
Article Abstract:
The results from a planetary transit search performed in a rich stellar field towards the Galactic bulge are reported. It is indicated that those orbiting very close to more-luminous stars are evaporatively destroyed or that jovian planets around stars of lower mass migrate to smaller radii.

The optical counterpart to gamma-ray burst GRB970228 observed using the Hubble Space Telescope
Article Abstract:
Several models have been proposed to explain the occurrence of astronomical gamma-ray bursts (GRBs), although there is a lack of obvious counterparts at other wavelengths. There has been recent detection of a transient optical counterpart in GRB970228 observed using the Hubble Space Telescope. There has been no change in the brightness of the source between the two dates observed,indicating that it is extragalactic, although the counterpart has since faded.
