When I was assigned the time in La Palma on the JKT, I gave thanks for my extraordinary luck that the observations were scheduled exactly at the perihelion of Comet LINEAR, or C/1999 S4 (LINEAR) as it is correctly known. This would be able to get data on the comet at the start of each night without interrupting the main programme. At the time I

We present Gran Telescopio CANARIAS CanariCam 8.7 μm imaging and 7.5-13 μm spectroscopy of six local systems known to host an active galactic nucleus (AGN) and have nuclear star formation. Our main goal is to investigate whether the molecules responsible for the 11.3 μm polycyclic aromatic hydrocarbon (PAH) feature are destroyed in the close

We present visible and near-IR spectra of the nucleus of comet 162P/Siding Spring (also known as 2004 TU12) obtained in 2004 December, while it had no detectable coma. This is the third object observed to have intermittent cometary activity even when relatively close to the Sun. The spectra show no strong features in this wavelength range. This

NN and Pi-N partial wave radial potentials have been generated using the latest SM94-VPI(NN) and FA93-VPI(Pi-N) phase shifts. The potentials are used to determine the deuteron properties and to compute the 3H and 3He binding energies. The e_1 mixing angles of SM94-VPI and NY93-Nijmegen differ significantly and inversion potentials yield a P_d of 6

The detection of 1.809 MeV gamma-ray line emission from the Vela region by the COMPTEL telescope presents a direct prove of recent nucleosynthesis activity in this region. It has been suggested that the observed 1.809 MeV emisson could arise from the radioactive decay of 26Al produced by the Vela SNR and/or the nearby Wolf-Rayet star γ2 Vel
