The radical anion spectra of C-60 and C-70 can be easily generated and studied in primary aliphatic amines. In these conditions the C-60-center dot and C-70-center dot species are accompanied by the dianions C-60(2-) and C-70(2-). In the near infrared region the electronic transitions at 1075, 1058 and 991 nm were assigned to C-60-center dot while

We present nucleosynthesis predictions for massive (5-7 M⊙) asymptotic giant branch (AGB) stars of solar metallicity where we delay the onset of the superwind to pulsation periods of P =700-800 days. We found that delaying the superwind in solar metallicity massive AGB stars results in a larger production of s-process elements, something that would

The ESO/MPG WFI and the INT WFC wide field archives comprising 330 000 images were mined to search for serendipitous encounters of known Near Earth Asteroids (NEAs) and Potentially Hazardous Asteroids (PHAs). A total of 152 asteroids (44 PHAs and 108 other NEAs) were identified using the PRECOVERY software, their astrometry being measured on 761

We present the analysis of a flux emergence event observed with the IMaX magnetograph flown aboard the SUNRISE balloon. IMaX took a 15' sequence with cadence of 31 s along the Fe I line at 525.0 nm, acquiring only Stokes I and V at 12 line positions (L12-2 mode). This sequence shows the emergence of a flux mantle at mesogranular scale, cospatial

The integrated molar absorptivity (Psi) and the molar extinction coefficient (epsilon) of each infrared transition of the hydrogenated fullerenes (known as fulleranes) C60H36, C70H38 and a mixture of fulleranes generally referred as 77% of C60Hx and 22% C70Hy with x approximate to y > 30 were determined. These data are useful for the search

The process of chemical self-enrichment in stellar systems can be affected by the total mass of the system and the conditions of the large-scale environment. Globular clusters are a special dark matter-free case of chemical evolution, in which the only self-enrichment comes from material processed in stars, and only two bursts of star formation
