Search for Kinematic Siblings of the Sun Based on Data from the XHIP Catalog [PDF]
Astronomy Letters, Vol.40, N 6, pp.352-359, 2014, 2014 From the XHIP catalogue, we have selected 1872 F-G-K stars with relative parallax measurement errors <20% and absolute values of their space velocities relative to the Sun <15 km/s. For all these stars, we have constructed their Galactic orbits for 4.5 Gyr into the past using an axisymmetric Galactic potential model with allowance made for the ...

Speckle Interferometry of Nearby Multiple Stars: 2007-2019 Positional Measurements and Orbits of Eight Objects [PDF]
The Astronomical Journal, 2020, V. 159, No. 6, P. 266, 2020 The orbits of 8 systems with low-mass components (HIP 14524, HIP 16025, HIP 28671, HIP 46199, HIP 47791, HIP 60444, HIP 61100 and HIP 73085) are presented. Speckle interferometric data were obtained at the 6 m Big Alt-azimuth Special Astrophysical Observatory of the Russian Academy of Sciences (BTA SAO RAS) from 2007 to 2019.

eLife, 2013 X-rays are best known for showing where bones have fractured, but researchers can also use X-rays to investigate why bones break, which could lead to treatments that reduce the number of elderly people who suffer broken hips.

HIPs and HIP-reactive T cells [PDF]
Clinical and Experimental Immunology, 2019 Summary Mounting evidence implicates hybrid insulin peptides (HIPs) as important autoantigens in the development of type 1 diabetes (T1D). These fusion peptides formed between insulin and other pancreatic beta cell-derived peptides contain non-genomically encoded amino acid sequences, making them plausible targets for autoreactive T ...

Total Hip Arthroplasty for Arthrodesed Hips [PDF]
Journal of Orthopaedic Surgery, 2002 The benefits of converting an ankylosed or arthrodesed hip to total hip arthroplasty have been reported in the literature as have the technical difficulties associated with this procedure.1,2,4 This review, however, outlines the experience of a single surgeon (WJMB) at a single institution using uncemented prostheses.

Adaptive optics imaging survey of the Tucana-Horologium association [PDF]
Astron.Astrophys. 404 (2003) 157-162, 2003 We present the results of an adaptive optics (AO) imaging survey of the common associations of Tucana and Horologium, carried out at the ESO 3.6m telescope with the ADONIS/SHARPII system. Based on our observations of two dozen probable association members, HIP 1910 and HIP 108422 appear to have low-mass stellar companions, while HIP 6856 and GSC 8047 ...

HIP 67506 C: MagAO-X Confirmation of a New Low-Mass Stellar Companion to HIP 67506 A [PDF]
, 2023 We report the confirmation of HIP 67506 C, a new stellar companion to HIP 67506 A. We previously reported a candidate signal at 2$\lambda$/D (240~mas) in L$^{\prime}$ in MagAO/Clio imaging using the binary differential imaging technique. Several additional indirect signals showed that the candidate signal merited follow-up: significant astrometric ...

Rocky planet engulfment in the binary system HIP 71726-37 [PDF]
arXiv, 2021 Binary stars are supposed to be chemically homogeneous, as they are born from the same molecular cloud. However, high precision chemical abundances show that some binary systems display chemical differences between the components, which could be due to planet engulfment.

Variability analysis of δ Scuti candidate stars [PDF]
, 2018 The Hipparcos catalog contains stars suspected to be {\delta} Scuti variables for which extensive ground-based observations and characterization of variability are necessary. Our aim was to characterize variability of 13 candidates to {\delta} Scuti type stars.
