The Solar Neighborhood LV: Spectral Characterization of an Equatorial Sample of 580 K Dwarfs
The Astronomical JournalWe present a spectroscopic characterization of 580 K dwarfs within 33 pc, observed with the CHIRON echelle spectrograph ( R = 80,000) on the SMARTS 1.5 m telescope. This volume-limited sample is part of the RKSTAR survey of ∼4400 K dwarf primaries within

Radio detection of late-type (G-K) dwarf stars in the Pleiades
, 1995 We report deep 3.6 cm radio observations of a small sample of the most rapidly rotating G-K dwarf stars in the Pleiades. Of the four ultrafast rotators (UFRs) observed, three were detected.

Widely separated binary systems of very low-mass stars
, 2005 In this paper we review some recent detections of wide binary brown dwarf systems and discuss them in the context of the multiplicity properties of very low-mass stars and brown ...

The Anatomical Record, EarlyView.Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

The Astrophysical Journal Supplement SeriesStellar X-ray emission serves as a direct diagnostic of coronal activity, which is fundamentally linked to coronal heating processes. It also strongly influences the atmospheres and long-term habitability of orbiting exoplanets.

The Anatomical Record, EarlyView.Abstract Cells derived from the endocardium, epicardium, cardiac neural crest, and second heart field play a critical role in the formation of the valvuloseptal structures of the heart. Previous studies have shown that the expression of the transcription factor SOX9 in these cell populations is essential in the regulation of this process.

The Anatomical Record, EarlyView.Abstract The obstetrical dilemma hypothesis (ODH) proposes an evolutionary trade‐off between obstetric requirements and locomotor performance. However, whether external pelvic breadth measures influence walking energetics during human growth remains poorly understood.

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies
Animal Research and One Health, EarlyView.Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

Searching for GEMS: Confirmation of TOI-5573 b, a Cool, Saturn-like Planet Orbiting an M Dwarf
The Astronomical JournalWe present the confirmation of TOI-5573 b, a Saturn-sized exoplanet on an 8.79 days orbit around an early M dwarf (3790 K, 0.59 R _⊙ , 0.61 M _⊙ , 12.30 Jmag). TOI-5573 b has a mass of $11{2}_{-19}^{+18}$ M _⊕ (0.35 ± 0.06 M _Jup ) and a radius of 9.75 ±

Spectroscopy of DENIS nearby stars candidates
, 2005 We present spectra of 36 nearby star candidates and 3 red giant candidates, identified in the DENIS database. 32 of the dwarf candidates are nearby red dwarfs, with spectral types from M 5.5 to M 8.5. Out of 11 targets with low proper motion (mu \u3c 0.1
