gyre_tides: Modeling Binary Tides within the GYRE Stellar Oscillation Code
The Astrophysical Journal, 2023 We describe new functionality in the GYRE stellar oscillation code for modeling tides in binary systems. Using a multipolar expansion in space and a Fourier-series expansion in time, we decompose the tidal potential into a superposition of partial tidal ...

High-angular resolution observations of the Pistol star [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractFirst results of near-IR adaptive optics (AO)-assisted imaging, interferometry, and spectroscopy of this Luminous Blue Variable (LBV) are presented. They suggest that the Pistol Star is at least double. If the association is physical, it would reinforce questions concerning the importance of multiplicity for the formation and evolution of ...

Prototype High Angular Resolution LEKIDs for NIKA2 [PDF]
Journal of Low Temperature Physics, 2018 The current resolution of the NIKA2 260 GHz arrays is limited by the $1.6\times 1.5 mm^2$ inductor size on the individual pixels. In view of future updates of the instrument, we have developed a prototype array with smaller pixels that is experimentally compared to the current pixel design.

High angular resolution neutron interferometry
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2011 The currently largest perfect-crystal neutron interferometer with six beam splitters and two interference loops offers novel applications in neutron interferometry. The two additional lamellas can be used for quantitative measurements of a phase shift due to crystal diffraction in the vicinity of a Bragg condition.

THE HIGH ANGULAR RESOLUTION MULTIPLICITY OF MASSIVE STARS [PDF]
The Astronomical Journal, 2009 We present the results of a speckle interferometric survey of Galactic massive stars that complements and expands upon a similar survey made over a decade ago. The speckle observations were made with the KPNO and CTIO 4 m telescopes and USNO speckle camera, and they are sensitive to the detection of binaries in the angular separation regime between 0 ...

Finsler geometry on higher order tensor fields and applications to high angular resolution diffusion imaging. [PDF]
, 2009 We study 3D-multidirectional images, using Finsler geometry. The application considered here is in medical image analysis, specifically in High Angular Resolution Diffusion Imaging (HARDI) (Tuch et al. in Magn. Reson. Med.

A statistical framework to characterise microstructure in high angular resolution diffusion imaging [PDF]
, 2008 High angular resolution diffusion imaging (HARDI) is an MR acquisition technique that has been used to identify and estimate multi-modal structure in white matter.

ATLAS search for new phenomena in dijet mass and angular distributions using pp collisions at s√=7 TeV [PDF]
, 2012 Mass and angular distributions of dijets produced in LHC proton-proton collisions at a centre-of-mass energy s√=7 TeV have been studied with the ATLAS detector using the full 2011 data set with an integrated luminosity of 4.8 fb−1. Dijet masses up to ~ 4.

Star formation at high angular resolution [PDF]
New Astronomy Reviews, 2004 The role of the SKA in high resolution observations of the formation of low and high mass stars in the Galaxy is examined. The large collecting area will have a large impact on dynamical studies at high resolution using spectral lines. The SKA will allow dramatic progress in the investigation of the ionised, atomic and molecular phases over a range of ...

Compact multi-aperture imaging with high angular resolution [PDF]
Journal of the Optical Society of America A, 2015 Previous reports have demonstrated that it is possible to emulate the imaging function of a single conventional lens with an N×N array of identical lenslets to provide an N-fold reduction in imaging-system track length. This approach limits the application to low-resolution imaging.
