A population synthesis study of the luminosity function of hot white dwarfs

, 2014
We present a coherent and detailed Monte Carlo simulation of the population of hot white dwarfs. We assess the statistical significance of the hot end of the white dwarf luminosity function and the role played by the bolometric corrections of hydrogen ...

Carbon Dots for Cancer Theranostics: Synthesis Strategies, Luminescence Properties, and Advances in Bioimaging‐Guided Diagnosis and Therapy

Chemistry – A European Journal, EarlyView.
Lighting up the path to precision oncology: This review comprehensively summarizes the rational design of carbon dots (CDs), elucidating how core size, surface chemistry, and heteroatom doping dictate their luminescence mechanisms. Special emphasis is placed on engineering NIR‐II emissive CDs for deep‐tissue imaging.

“Train and Hope”: The Role of Restorative Justice Coordinators in Sustaining a Culture of Care in Schools

Conflict Resolution Quarterly, EarlyView.
ABSTRACT This article examines the role of restorative justice coordinators in supporting teachers and schools in adopting a whole‐school approach to restorative justice in education. Coordinators are often tasked with implementing a train‐and‐hope model, in which they receive initial training in restorative justice but are largely left unsupported ...

Dilution of accreted planetary matter in hot DA white dwarfs according to their mass

Astronomy & Astrophysics
Context. A large proportion of observed white dwarfs show evidence of debris disks, remnants of the former planetary systems, and/or signatures of heavy elements in their atmospheres, induced by the accretion of planetary matter onto their surfaces.

Kinetic Contribution to the Arbitrary Order Odd Frequency Moments of the Dynamic Structure Factor

Contributions to Plasma Physics, EarlyView.
ABSTRACT An exact expression is derived for the kinetic contribution to the odd (arbitrary order) frequency moments of the dynamic structure factor via a finite summation that features averages of even (all lower orders) powers of the momentum over the exact momentum distribution.

MAGNETISM OF WHITE DWARFS (intermediate results of a survey for kilogauss magnetic fields in white dwarfs)

Odessa Astronomical Publications, 2017
We shortly present intermidiate results of a survey for weak magnetic fields among degenerate stars (white dwarfs and hot subdwarf stars). Kilogauss upper limits of longitudinal magnetic fields are presented for several brightest DA white dwarfs and new ...

A study of high proper-motion white dwarfs I. Spectropolarimetry of a cool hydrogen-rich sample

, 2012
We conducted a spectropolarimetic survey of 58 high proper-motion white dwarfs which achieved uncertainties of >2 kG in the Halpha line and >5 kG in the upper Balmer line series.

Edge Fluid Turbulence Simulations of Stellarators With GRILLIX

Contributions to Plasma Physics, EarlyView.
ABSTRACT The edge fluid turbulence code GRILLIX has recently been extended from axisymmetric tokamak geometries to support 3D stellarator configurations. Following successful proof‐of‐principle simulations published in Stegmeir et al., we present here a comprehensive simulation of the Wendelstein 7‐AS stellarator.

A White Dwarf Catalog from LAMOST DR11 Using Deep Learning

The Astrophysical Journal Supplement Series
White dwarfs, also referred to as degenerate dwarfs, represent the ultimate fate for the majority of stars in the Universe, unless their mass is large enough for them to evolve into black holes or neutron stars.
