    Chromospheric Activity of HAT-P-11: an Unusually Active Planet-Hosting K Star

    Full text link
    Kepler photometry of the hot Neptune host star HAT-P-11 suggests that its spot latitude distribution is comparable to the Sun's near solar maximum. We search for evidence of an activity cycle in the CaII H & K chromospheric emission SS-index with archival Keck/HIRES spectra and observations from the echelle spectrograph on the ARC 3.5 m Telescope at APO. The chromospheric emission of HAT-P-11 is consistent with a 10\gtrsim 10 year activity cycle, which plateaued near maximum during the Kepler mission. In the cycle that we observed, the star seemed to spend more time near active maximum than minimum. We compare the logRHK\log R^\prime_{HK} normalized chromospheric emission index of HAT-P-11 with other stars. HAT-P-11 has unusually strong chromospheric emission compared to planet-hosting stars of similar effective temperature and rotation period, perhaps due to tides raised by its planet.Comment: 16 pages, 8 figures; accepted to the Astrophysical Journa

    Understanding the Nanostructure Formation of the Templated Two-Phase Film Growth via Hybrid Modeling

    No full text
    A hybrid model incorporating two methods, i.e., the Potts model Monte Carlo and the level set method, is developed to simulate the templated growth of a two-phase CoPt/SiO<sub>2</sub> thin film. Previously it was demonstrated experimentally that the film grown on the prefabricated template followed the pattern of the template, forming a highly ordered microstructure. The simulation in this study investigates the physical mechanism by which such film growth behavior occurs and which parameters dictate the resultant microstructure. To correctly represent the physical process, the interfacial energies between different phases and the rate of each microevent to occur were established through the simulated film deposition on a flat substrate and subsequent comparison to the experimental observations. With the established interfacial energy and rate of microevents, the resultant film microstructure grown on the templated substrate is found to strongly depend on the geometries of domes fabricated on the template. The dominant mechanism of the formation of the microstructure is shown to shift from the surface energy gradient controlled lateral diffusion in the initial stage of film growth, which formed the rudiment of the ordered microstructure, to an interfacial energy controlled process, which retained the ordered microstructure in the later stage
