Constitution of the White Dwarf Stars [PDF]
Nature, 1931 IT is generally held that the white dwarf is in the degenerate state in the sense of the statistics of Fermi and Dirac. This assumption leads to another consequence bearing on the relative abundance of elements in the same star. Assuming further that (i) all atoms of various elements in the white dwarf are stripped of their extranuclear electrons, and (

Bricks, knots, and bodies: Material encounters and the affective making of masculinity
British Educational Research Journal, EarlyView.Abstract This paper examines how creative research methods do not just capture boys' experiences of masculinity, but actively materialise them. Drawing on two arts‐based activities used in school‐based fieldwork (a mannequin‐based exercise with one participant and a Lego‐building workshop with a small peer group), the paper analyses how materials ...

When Nature Counts: Corporate Biodiversity Attention and Access to Bank Finance
Business Strategy and the Environment, EarlyView.ABSTRACT This paper investigates whether corporate attention to biodiversity influences firms' access to bank loans, an overlooked question in the emerging biodiversity–finance literature. Using a novel, text‐based measure constructed from 446 biodiversity‐related keywords and applied to Chinese A‐share listed firms from 2000 to 2023, we show that ...

Asteroseismology of One of the Most Rapidly Rotating DBV Stars: EPIC 248705247
The Astrophysical JournalWe present a comprehensive analysis of oscillations of the helium-rich white dwarf DBV star EPIC 248705247 (SDSS J102106.69+082724.8). We extract the light curves from 79.7 days of K2 Campaign 14 data and identify 21 independent frequencies, including ...

White dwarf pollution: one star or two?
Monthly Notices of the Royal Astronomical SocietyABSTRACT The accretion of tidally disrupted planetary bodies is the current consensus model for the presence of photospheric metals commonly detected in white dwarfs. While most dynamical studies have considered a single star and associated planetary instabilities, several investigations have instead considered the influence of widely ...

Asteroseismology of white dwarf stars [PDF]
Highlights of Astronomy, 1995 Perhaps the hardest scientific problems to solve are those most scientists believe have already been solved, but which have not. Any model we make of an astronomical process is doomed to be incomplete at some level; the “broad-brush” picture of stellar structure and evolution is often accepted as a solved problem, but in fact many discrepancies exist ...
