Observations of SN 1988A in M58 are presented which show a remarkable departure from Co-56 decay in the optical light curve starting about 700 days since explosion. It is shown that the departure cannot be explained by the contribution from other radioactive isotopes to the late luminosity, and fluorescence in nearby clouds can be excluded as the

One of the proposed damping mechanisms of coronal transverse loop oscillations in the kink mode is resonant absorption as a result of the spatial variation of the Alfvén velocity in the equilibrium configuration. Analytical expressions for the period and the damping time exist for 1-D cylindrical equilibrium models with thin non-uniform

The prime objectives of the workshop were to: inform the community about the science opportunities of the Solar Orbiter mission; to provide a forum for sharpening and focussing the science goals; allow the hardware groups and instrument proposers to critically review the payload; establish international contacts and collaborations.

We characterize the K I D1 & D2 lines in order to determine whether they could complement the 850 nm window, containing the Ca II infrared triplet lines and several Zeeman sensitive photospheric lines, that was studied previously. We investigate the effect of partial redistribution on the intensity profiles, their sensitivity to changes in

During the Space Telescope and Optical Reverberation Mapping Project observations of NGC 5548, the continuum and emission-line variability became decorrelated during the second half of the six-month-long observing campaign. Here we present Swift and Chandra X-ray spectra of NGC 5548 obtained as part of the campaign. The Swift spectra show that
