Angular Momentum Loss from Cool Stars: An Empirical Expression and Connection to Stellar Activity

, 2011
We show here that the rotation period data in open clusters allow the empirical determination of an expression for the rate of loss of angular momentum from cool stars on the main sequence.

Scoliosis Surgery in a Patient With Advanced Friedreich's Ataxia—It Is Not Too Late

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Friedreich's ataxia is a multisystem disorder with scoliosis being the most common non‐neurological manifestation. While scoliosis surgery is typically performed in adolescent, ambulatory patients, few data exist on surgical outcomes in patients with advanced disease.

What Physical Factors Influence the Transformation between Blue Supergiants and Red Supergiants?

The Astrophysical Journal
The post-main-sequence evolution of massive stars is highly sensitive to key stellar model parameters, particularly initial rotational velocity and metallicity.

Evidence from stellar rotation of enhanced disc dispersal: (I) The case of the triple visual system BD-21 1074 in the $\beta$ Pictoris association

, 2014
The early stage of stellar evolution is characterized by a star-disc locking mechanism. The disc-locking prevents the star to spin its rotation up, and its timescale depends on the disc lifetime.

Starspot Area Coverage: Correlation with Age and Spectral Type in FGK and M Stars

The Astrophysical Journal Letters
Starspots, analogous to sunspots, are surface manifestations of stellar magnetic activity. Their study provides crucial insights into stellar dynamo processes and the evolution of magnetic phenomena.

Prevalence of Pincer Morphology in Early Adolescents From the General Population: A Population‐Based Study

Arthritis Care &Research, EarlyView.
Objective Pincer morphology can lead to femoroacetabular impingement syndrome (FAIS) and may be a modifiable risk factor for hip osteoarthritis (OA). Currently, no studies investigate the prevalence of pincer morphology in early adolescence, which is the period when this bony shape likely develops.

Effects of gravitational darkening on the determination of fundamental parameters in fast rotating B-type stars

, 2005
In this paper we develop a calculation code to account for the effects carried by fast rotation on the observed spectra of early-type stars. Stars are assumed to be in rigid rotation and the grid of plane-parallel model atmospheres used to represent the ...

Lived and Care Experiences of Chronic Musculoskeletal Shoulder Pain in Australian Adults: A Qualitative Study

Arthritis Care &Research, EarlyView.
Objective Australian evidence on lived and care experiences of chronic musculoskeletal shoulder pain (CMSP), irrespective of disorder classification or disease, is limited. However, such evidence is important for person‐centered care and informing local service pathways and care guidelines or standards.
