    Heliocentric distance dependence of zodiacal light observed by Hayabusa2#
    Zodiacal light (ZL) is sunlight scattered by interplanetary dust particles (IDPs) at optical wavelengths. The spatial distribution of IDPs in the Solar System...
  • Publication
    Helioseismic evidence of two solar granulation timescales
    The signature of two different scales of solar granulation in the power spectrum of disk integrated irradiance time series is presented. The fitted timescales...

    Helioseismic holography of simulated sunspots: dependence of the travel time on magnetic field strength and Wilson depression
    Improving methods for determining the subsurface structure of sunspots from their seismic signature requires a better understanding of the interaction of waves...
  • Publication
    Helioseismic Holography of Simulated Sunspots: Magnetic and Thermal Contributions to Travel Times
    Wave propagation through sunspots involves conversion between waves of acoustic and magnetic character. In addition, the thermal structure of sunspots is very...

    Helioseismic Signature of Parker Fragmentation of Magnetic Flux beneath Sunspot Photospheres
    Standard local helioseismic diagnostics of large sunspots show the signature of anomalously strong compact scatterers of p-modes within about 1 Mm beneath their...
  • Publication
    Helioseismic Studies of Differential Rotation in the Solar Envelope by the Solar Oscillations Investigation Using the Michelson Doppler Imager
    The splitting of the frequencies of the global resonant acoustic modes of the Sun by large-scale flows and rotation permits study of the variation of angular...

    Helium abundances and its radial gradient from the spectra of H II regions and ring nebulae of the Milky Way
    We determine the radial abundance gradient of helium in the disc of the Galaxy from published spectra of 19 H II regions and ring nebulae surrounding massive O...
