  • The Gaia-ESO survey: Calibrating a relationship between age and the [C/N] abundance ratio with open clusters

    Context. In the era of large high-resolution spectroscopic surveys such as Gaia-ESO and APOGEE, high-quality spectra can contribute to our understanding of the Galactic chemical evolution by providing abundances of elements that belong to the different nucleosynthesis channels, and also by providing constraints to one of the most elusive

  • Toluene pyrolysis in an electric ARC: Products analysis

    Toluene pyrolysis in a submerged carbon arc produced at least 72 different molecular species as detected by gas-chromatography coupled with mass spectrometry (GC-MS). The most abundant products found were bibenzyl (1,2-diphenylethane), naphthalene and biphenylene. Furthermore, also diethynylbenzene isomers, fluorene, diphenymethane, indene and

  • Far infrared spectroscopy and other spectral and thermal properties of [Li@C60]PF6

    The endohedral fullerene [Li@C60]+PF6− was characterized by differential scanning calorimetry (DSC), by electronic absorption spectroscopy in the spectral range from 195 to 800 nm and by FT-IR and far-infrared spectroscopy. [Li@C60]+PF6− shows a sharp melting point with the onset at 86 °C and peak at 90 °C and melting enthalpy of 9.5 kJ/mol. The

  • FT-IR spectroscopy of carbonized acenes: a possible key for the UIBs/AIBs origins

    The complete acene series from naphthalene to anthracene, tetracene and pentacene were carbonized directly in a differential scanning calorimeter (DSC) special crucible heating up to 700 °C under autogenous pressure. In these conditions the carbonization of all the acenes was detected as an endothermal process occurring above 550 °C. The resulting

  • Low-frequency gravity waves in blue supergiants revealed by high-precision space photometry

    Almost all massive stars explode as supernovae and form a black hole or neutron star. The remnant mass and the impact of the chemical yield on subsequent star formation and galactic evolution strongly depend on the internal physics of the progenitor star, which is currently not well understood. The theoretical uncertainties of stellar interiors

  • K2-295 b and K2-237 b: Two Transiting Hot Jupiters

    We report the discovery from K2 of two transiting hot Jupiter systems. K2-295 (observed in Campaign 8) is a K5 dwarf which hosts a planet slightly smaller than Jupiter, orbiting with a period of 4.0 d. We have made an independent discovery of K2-237 b (Campaign 11), which orbits an F9 dwarf every 2.2 d and has an inflated radius 60-70% larger than
