Field Blue Stragglers and Related Mass Transfer Issues

, 2014
This chapter contains my impressions and perspectives about the current state of knowledge about field blue stragglers (FBS) stars, drawn from an extensive literature that I searched. I conclude my review of issues that attend FBS and mass transfer, by a

The Formation Rate of Blue Stragglers in 47 Tucanae [PDF]

, 1999
We investigate the effects of changes in the blue straggler formation rate in globular clusters on the blue straggler distribution in the color-magnitude diagram. We find that the blue straggler distribution is highly sensitive to the past formation rate.

HUBBLE SPACE TELESCOPE PROPER MOTION (HSTPROMO) CATALOGS OF GALACTIC GLOBULAR CLUSTERS. IV. KINEMATIC PROFILES AND AVERAGE MASSES OF BLUE STRAGGLER STARS [PDF]

, 2016
We make use of the Hubble Space Telescope proper-motion catalogs derived by Bellini et al. to produce the first radial velocity dispersion profiles for blue straggler stars (BSSs) in Galactic globular clusters (GCs), as well as the first dynamical ...

Néel Tensor Torque in Polycrystalline Antiferromagnets

Advanced Materials, EarlyView.
This work introduces a Néel tensor torque based on a rank‐two symmetric tensor capturing spin correlations in a polycrystalline antiferromagnet. It shows the Néel tensor can be shaped and reshaped through the spin‐orbit torque (SOT) technique, enabling field‐free SOT switching with a specific polarity of the adjacent ferromagnet. This discovery opens a

UOCS XIV: Study of the Open Cluster NGC 2627 Using UVIT/AstroSat

The Astronomical Journal
We study the intermediate-age open cluster NGC 2627, located at a distance of ∼2 kpc, using UVIT/AstroSat and other archival data. Using a machine learning-based algorithm, ML-MOC, on the Gaia DR3 data, we identify 422 cluster members, including four ...

A halo blue straggler on a highly eccentric retrograde orbit [PDF]

, 2010
Blue straggler, which are stars that appear to be younger than they should be, are an important population of unusual stars in both stellar clusters and the halo field of the Galaxy.

Nonreciprocal Spin Waves in Nanoscale Hybrid Néel–Bloch–Néel Domain Walls Detected by Scanning X‐Ray Microscopy in Perpendicular Magnetic Anisotropic Fe/Gd Multilayers

Advanced Materials, EarlyView.
Using scanning transmission X‐ray microscopy, nonreciprocal spin‐wave behavior is revealed in real space in Fe/Gd multilayers with perpendicular magnetic anisotropy, highlighting their functionality for magnonic logic circuits operating at GHz frequencies.

Unveiling Bifurcated Blue Straggler Sequences in NGC 2173: Insights from Binary Evolution

The Astrophysical Journal
Identifying bifurcated blue straggler (BS) sequences in color–magnitude diagrams (CMDs) of star clusters has long been regarded as a powerful diagnostic for distinguishing different BS formation mechanisms.
