Description
Photometric observations of a wide and a narrow outburst of the dwarf nova SS Cygni are used to test the hypothesis that the same mechanism is responsible for the wide outbursts of U Gem stars and the wide outbursts of SU UMa stars. A search for modulations at or near the orbital period of the SS Cygni outbursts was conducted, showing no modulations to a limit of about 0.05 mag. The results are interpreted by Whitehurst's (1984) tidal superhump model which suggests that SU UMa and U Gem outbursts are manifestations of the same basic driving mechanism, but that the presence of superhumps is limited to extreme mass-ratio systems.

    An ultra-short-period super-Earth with an extremely high density and an outer companion
    We present the discovery and characterization of a new multi-planetary system around the Sun-like star K2-360 (EPIC 201595106). K2-360 was first identified in K2 photometry as the host of an ultra-short-period (USP) planet candidate with a period of 0.88 d. We obtained follow-up transit photometry, confirming the star as the host of the signal

    Dehydrogenation, polymerization and self-assembly in the inhibition of copper surfaces by an ultrathin imidazole film
    Here we present a joint experimental-theoretical study on the deposition of imidazole molecules on a Cu(100) surface. X-ray photoelectron spectroscopy (XPS) and Surface-enhanced Raman spectroscopy (SERS) have been carried out on samples prepared upon deposition of sublimated imidazole molecules in ultra-high vacuum (UHV).

    Constraints on VHE gamma-ray emission of flat spectrum radio quasars with the MAGIC telescopes
    Flat spectrum radio quasars (FSRQs) constitute a class of jetted active galaxies characterized by a very luminous accretion disc, prominent and rapidly moving line-emitting cloud structures (broad-line region, BLR), and a surrounding dense dust structure known as dusty torus. The intense radiation field of the accretion disc strongly determines the
