Fulleranes, the hydrogenated fullerenes C60H36 and C60D36 have been synthesized in n-hexane where they show an absorption maximum at 217 nm in their electronic absorption spectra with molar extinction coefficients ɛ217 = 17140 and 16480L cm-1 mol-1, respectively, which correspond to absorption cross-sections of order 6500 Mbarn, about 10 times

We present a quantitative analysis of the star formation history (SFH) of 12 fields in the Small Magellanic Cloud (SMC) based on unprecedented deep [(B - R), R] color-magnitude diagrams (CMDs). Our fields reach down to the oldest main-sequence turnoff with a high photometric accuracy, which is vital for obtaining accurate SFHs, particularly at

Se han analizado series temporales de las fluctuaciones de la irradiancia solar integrada sobre el disco provenientes del experimento espacial "Variability of the solar IRradiance and Gravity Oscillations" (VIRGO) durante dos épocas correspondientes una, a un máximo de actividad magnética, y la otra, a un mínimo. En cada caso, se han ajustado las
