White dwarfs are a class of stars with unique physical properties. They present many
challenging problems whose solution requires advanced theories of dense matter, state-of …

Magnetic storms on stars manifest as remarkable, randomly occurring changes of the
luminosity over durations that are tiny in comparison to the normal evolution of stars. These …

Redshifted components of chromospheric emission lines in the hard X-ray impulsive phase
of solar flares have recently been studied through their 30 s evolution with the high …

Understanding how atoms interact with hot dense matter is essential for astrophysical and
laboratory plasmas. Interactions in high-density plasmas broaden spectral lines, providing a …

Spectral line-shape models are an important part of understanding high-energy-density
(HED) plasmas. Models are needed for calculating opacity of materials and can serve as …

White dwarfs (WDs) are useful across a wide range of astrophysical contexts. The
appropriate interpretation of their spectra relies on the accuracy of WD atmosphere models …

He β spectral line shapes are important for diagnosing temperature and density in many
dense plasmas. This work presents He β line shapes measured with high spectral resolution …

This work communicates a review on Balmer series hydrogen beta line measurements and
applications for analysis of white dwarf stars. Laser-induced plasma investigations explore …

In the era of modern digital sky surveys, uncertainties in the flux of stellar standards are
commonly the dominant systematic error in photometric calibration and can often affect the …

The spectroscopic method relies on hydrogen Balmer absorption lines to infer white dwarf
(WD) masses. These masses depend on the choice of atmosphere model, hydrogen atomic …
