The hydrogenated C70 fullerenes C70H38 and C70D38 have been photolyzed at 245nm under Ar or He flow. The photolysis rate constant have been measured: k = 1.54x10-3s-1 for C70H38, and the photolysis of C70D38 occurs at a rate of 1.17x10-3s-1. A remarkable isotope effect in the photolysis of the two molecules has been determined kH/kD = 1.32. The

The MAGIC collaboration has recently reported the discovery of γ-ray emission from the binary system LS I +61°303 in the TeV energy region. Here we present new observational results on this source in the energy range between 300 GeV and 3 TeV. In total, 112 hr of data were taken between 2006 September and December covering four orbital cycles of

Perdeutero[70]fullerane, C70D38 and the hydrogenated analogous C70H38 have been synthesized using nascent deuterium or hydrogen generated by the action of DCl or HCl on Zn dust in toluene or benzene solvents. The FT-IR spectra of C70D38 and C70H38 have been studied. A better oxidation stability of C70D38 has been observed by FT-IR spectroscopy in

We present high-speed optical photometry of the anomalous X-ray pulsar 1E1048.1-5937 obtained with ULTRACAM on the 8.2-m Very Large Telescope in 2007 June. We detect 1E1048.1-5937 at a magnitude of i' = 25.3 +/- 0.2, consistent with the values found by Wang et al. and hence confirming their conclusion that the source was approximately 1mag brighter

GX 339-4 is currently brightening at X-ray, UV, optical and radio frequencies (ATel #1945, #1954, #1960). Our monitoring campaign with the Faulkes Telescope South (ATel #1586) gives the following recent magnitudes (light curves are below; errors are ~ 0.02 mag): 2009-02-20 (MJD 54882.65): i' ~ 16.66 (and varying by ~ 0.2 mag in 10 minutes) 2009-02
