80Integral Field Spectroscopy of the Low-mass Companion HD 984 B with the Gemini Planet ImagerAstronomical Journal 153 (4): 190. 2017.© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity of 0.18 with a 68% confidence interval between 0.05 …Read more

27Degree of structural perfection of icosahedral quasicrystalline grains investigated by synchrotron X-ray diffractometry and imaging techniquesPhilosophical Magazine 83 (1): 1-29. 2003.A study of the structural perfection of icosahedral quasicrystalline grains of various alloys and Al-Cu-Fe), grown by different slow solidification techniques was performed using high-resolution diffraction, including recording rocking curves combined with X-ray topography and phase contrast radiography, at a third-generation synchrotron radiation source . For Al-Pd-Mn, additional coherent diffraction and diffuse scattering measurements were also carried out. After evaluating the potentialities …Read more
