    Spectral Irradiance Calibration in the Infrared. X. A Self-Consistent Radiometric All-Sky Network of Absolutely Calibrated Stellar Spectra
    We start from our six absolutely calibrated continuous stellar spectra from 1.2 to 35 μm for K0, K1.5, K3, K5, and M0 giants. These were constructed as far as...

    Spectral Irradiance Calibration in the Infrared. XIII. ``Supertemplates'' and On-Orbit Calibrators for the SIRTF Infrared Array Camera
    We describe the technique that will be used to develop a set of on-orbit calibrators for the Infrared Array Camera (IRAC) and demonstrate the validity of the...

    Spectral properties of near-Earth objects with low-Jovian Tisserand invariant
    The near-Earth objects with low-Jovian Tisserand invariant (T J) represent about 9 per cent of the known objects orbiting in the near-Earth space, being subject...

    Spectro-photometric decomposition of galaxy structural components
    Galaxies are complex systems made up of different structural components such as bulges, discs, and bars. Understanding galaxy evolution requires unveiling...

    Spectropolarimetric Evidence for a Siphon Flow along an Emerging Magnetic Flux Tube
    We study the dynamics and topology of an emerging magnetic flux concentration using high spatial resolution spectropolarimetric data acquired with the Imaging...

    Spectropolarimetric inversions of the He I 10830 Å multiplet in an active region filament.
    Full-Stokes spectropolarimetric data (in the 10830 Å region) of an active region filament were obtained in July 2005 using the Tenerife Infrared Polarimeter...

    Spectropolarimetric Investigation of the Propagation of Magnetoacoustic Waves and Shock Formation in Sunspot Atmospheres
    Velocity oscillations in sunspot umbrae have been measured simultaneously in two spectral lines: the photospheric Si I λ10827 line and the chromospheric He I...
