PublicationThe longest thermonuclear X-ray burst ever observed?. A BeppoSAX Wide Field Camera observation of 4U 1735-44
A long flux enhancement, with an exponential decay time of 86 min, is detected in 4U 1735-44 with the BeppoSAX Wide Field Cameras. We argue that this is a type...

PublicationThe low L solar p-mode spectrum at maximum and minimum solar activity
Velocity measurements of disc integrated sunlight obtained at the Observatorio del Teide (Izana) from 1980 throughout 1989 are used to find the frequencies and...

PublicationThe low-excitation structures of planetary nebulae
The low excitation properties of the planetary nebula (PN) NGC 6720 are known to be unusual, and to imply large ring/core emission ratios. We point out that...
