A spectroscopic study of the blue stragglers in M67 [PDF]
Monthly Notices of the Royal Astronomical Society, 2008 Based on spectrophotometric observations from the Guillermo Haro Observatory (Cananea, Mexico), a study of the spectral properties of the complete sample of 24 blue straggler stars (BSs) in the old Galactic open cluster M67 (NGC 2682) is presented. All spectra, calibrated using spectral standards, were recalibrated by means of photometric magnitudes in

Seasonal resource selection and movement ecology of free‐ranging horses in the western United States
The Journal of Wildlife Management, Volume 87, Issue 2, February 2023., 2023 Feral horses selected for areas of high herbaceous vegetation and avoided forest but moved to higher elevations in winter. Surface water influenced movement patterns for harem groups, whereas bachelor males moved faster, farther, and were less constrained by water availability than harems. Because of the importance of surface water, strategic placement

A chemical study of M67 candidate blue stragglers and evolved blue stragglers observed with APOGEE DR14 [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 Within the variety of objects populating stellar clusters, blue straggler stars (BSSs) are among the most puzzling ones. BSSs are commonly found in globular clusters, but they are also known to populate open clusters of the Milky Way. Two main theoretical scenarios (collisions and mass transfer) have been suggested to explain their formation, although ...

A comparative study on corrosion failure analysis of hearing aid devices from different markets
Materials and Corrosion, Volume 74, Issue 1, Page 159-173, January 2023., 2023 The miniaturized design trend in hearing aids has caused a tremendous reduction in sizes for electronic parts and assembly, and as a result, the robustness of the device towards corrosion‐induced failures is compromised. In this study, a large number of field‐failed hearing aid devices across different markets were analyzed to understand their failure ...

The Astrophysical Journal Supplement Series, 2023 Using data from Gaia Data Release 3 and Kepler/K2, we present a catalog of 16 open clusters with ages ranging from 4–4000 Myr that provides detailed information on membership, binary systems, and rotation. We assess the memberships in 5D phase space, and

The lithium abundance of M67 blue stragglers - A constraint on the blue straggler phenomenon
The Astrophysical Journal, 1991 Upper limits have been placed on the line strength of the 6707 A Li I resonance doublet in seven blue stragglers in M67. The corresponding upper limits on abundances range from log N(Li) less than about 1.3 to less than about 2.3. This result is significantly below the level of log N(Li) about 3.1 + or {minus} 0.1 found in field main-sequence stars of ...

Blue Straggler Bimodality: A Brownian Motion Model [PDF]
The Astrophysical Journal, 2018 Abstract The shape of the radial distribution of blue straggler stars (BSS), when normalized to a reference population of horizontal branch (HB) stars, has been found to be a powerful indicator of the dynamical evolution reached by a globular cluster (GC).

Research in Nursing &Health, Volume 46, Issue 1, Page 68-79, February 2023., 2023 Abstract Studies examining the associations of chronic stressors with sleep health in older adults have shown conflicting results. While the COVID‐19 pandemic increased perceived stress at the population level, less is known about chronic stressors experienced by older adults in the context of the COVID‐19 pandemic and its impact on sleep health in an ...
