Hydrogen-Atmosphere White Dwarfs Are Less Likely To Be Found with Wide-Binary Companions [PDF]

arXiv
The fraction of white dwarfs found in wide binaries is estimated by cross referencing a catalogue of wide binaries with catalogues photometrically determined white-dwarf candidates and spectroscopically confirmed white dwarf stars. The wide-binary fraction of white dwarfs with hydrogen-dominated atmospheres is about 5%, but the fraction of white dwarfs

Remediation of the picture‐text problem for learners exhibiting reading deficits

Journal of Applied Behavior Analysis, EarlyView.
Abstract Early reading materials are replete with pictures. Pictures purportedly improve reading comprehension and motivation; however, the simultaneous presentation of pictures and text can also impede textual control for some readers. Attempts to remediate restricted stimulus control in picture–text compounds suggest that omitting the picture element

The MIRI Exoplanets Orbiting White dwarfs (MEOW) Survey: Mid-infrared Excess Reveals a Giant Planet Candidate around a Nearby White Dwarf

The Astrophysical Journal Letters
The MIRI Exoplanets Orbiting White dwarfs survey is a cycle 2 JWST program to search for exoplanets around dozens of nearby white dwarfs via infrared excess and direct imaging.

Investigating the reasons behind a later or missed diagnosis of attention‐deficit/hyperactivity disorder in young people: A population cohort study

JCPP Advances, EarlyView.
Abstract Background Attention Deficit Hyperactivity Disorder (ADHD) is a common neurodevelopmental condition, more often diagnosed in males. In many individuals, particularly females, ADHD is diagnosed later or missed, the reasons for this are not fully understood.

The White Dwarf Pareto: Tracing Mass Loss in Binary Systems

The Astrophysical Journal
The white dwarf mass distribution has been studied primarily at two extremes: objects that presumably evolved as single stars, and members of close binaries that likely underwent substantial interaction.

Static and rotating white dwarfs at finite temperatures [PDF]

arXiv, 2019
Static and uniformly rotating, cold and hot white dwarfs are investigated both in Newtonian gravity and general theory of relativity, employing the well-known Chandrasekhar equation of state. The mass-radius, mass-central density, radius-central density etc relations of stable white dwarfs with $\mu=A/Z=2$ and $\mu=56/26$ (where $A$ is the average ...

Age is not a primary risk factor for ACL injury—A comprehensive review of ACL injury and reinjury risk factors confounded by young patient age

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Revision surgery after anterior cruciate ligament reconstruction (ACL‐R) is hypothesized to be the result of an interplay between factors associated with the anatomy, physiological characteristics and environment of the patient. The multifactorial nature of revision ACL‐R risk is difficult to quantify, and evidence regarding the independent ...
