This is a progress report on a project to characterize the surface composition (and other properties such as radius, albedo and thermal inertia) of a sample of...

Maps of a 3 by 2 arcmin region of the inner coma of comet Halley, at 10 arcsec resolution, in several principal atomic and molecular species were prepared by...

The authors present low resolution maps, of a four by one half arcminute region, of comet Halley, in photometric bands J and K, and central scan in the H band...

Solar gravity (g) modes propagate within the radiative part of the solar interior and are highly sensitive to the physical conditions of the solar core. They...

We present new results of a program aimed at studying the physical properties, origin and evolution of those phenomena which go under the somewhat generic...

WEAVE is a wide-field spectroscopy facility for WHT which includes a multi-object dual-beam spectrograph which will operate in the visible wavelength range. The...
