    Hectochelle: A Multiobject Optical Echelle Spectrograph for the MMT
    The Hectochelle is an optical band, fiber-fed, multiobject echelle spectrograph deployed at the MMT Observatory on Mount Hopkins, Arizona. The optical fibers...

    Height Dependence of the Penumbral Fine-scale Structure in the Inner Solar Atmosphere
    We studied the physical parameters of the penumbra in a large and fully developed sunspot, one of the largest over the last two solar cycles, by using full...

    Height variation of the cutoff frequency in a sunspot umbra
    Context. In the solar atmosphere, the acoustic cutoff frequency is a local quantity that depends on atmospheric height. It separates low-frequency evanescent...

    Height Variation of the Vector Magnetic Field in Solar Spicules
    Proving the magnetic configuration of solar spicules has hitherto been difficult due to the lack of spatial resolution and image stability during off-limb...
  • Publication
    Heights of formation for measurements of atmospheric parameters.
    We argue that heights of formation (HOFs) should not be assigned to spectral lines since a single line my sample very different layers of the atmosphere...

    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...
  • Publication
    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...
