The Impact of Breathing Pulses during Core Helium Burning on the Core Chemical Structure and Pulsations of Hydrogen-rich Atmosphere White Dwarfs

open access: yesThe Astrophysical Journal
Breathing pulses are mixing episodes that could develop during the core helium-burning phase of low- and intermediate-mass stars. The occurrence of breathing pulses is expected to bear consequences on the formation and evolution of white dwarfs ...

Unearthing the impact of earthquakes: A review of economic and social consequences

open access: yesJournal of Policy Analysis and Management, EarlyView.
Abstract The purpose of this paper is to offer a comprehensive overview of the socioeconomic effects of earthquakes. We begin with a thorough literature review. Following this, we assess policy measures taken in response to major earthquakes, drawing on existing research to formulate insights and recommendations that policymakers can use to effectively

A Short Intense Dynamo at the Onset of Crystallization in White Dwarfs

open access: yesThe Astrophysical Journal Letters
The origin of large magnetic fields (≳10 ^6 G) in isolated white dwarfs is not clear. One possible explanation is that crystallization of the star’s core drives compositional convection, which when combined with the star’s rotation, can drive a dynamo ...

We are storytelling apes: Experimenting with new scientific narratives in a time of climate and biodiversity collapse

open access: yesPeople and Nature, EarlyView.
Abstract Provoked by a lack of appropriate political action on the global climate and biodiversity crisis, we present a perspective advocating and demonstrating a new plurality in scientific communication methods. Science writing, in being objective and dispassionate, actively seeks to mask empathetic connection and hides curiosities that may exist ...

Predicted scarcity of suitable habitat for alpine plant communities in northern Japan under climate change

open access: yesApplied Vegetation Science, Volume 25, Issue 4, October/December 2022., 2022
We estimated the future distribution of alpine and subalpine vegetation types under climate change in the Taisetsu Mountains, Daisetsuzan National Park, Hokkaido (northern Japan). Under the RCP2.6 scenario, habitats suitable for snowbeds and alpine heathland/fellfield drastically decreased overall.

Constraining the origin of magnetic white dwarfs [PDF]

open access: yesarXiv
The origin of magnetic white dwarfs has been a long standing puzzle. Proposed origin mechanisms have included: fossil fields frozen in from the progenitor convective core; a dynamo in the progenitor envelope; crystallization dynamos in sufficiently cool white dwarfs; and accretion disk dynamos from white dwarf-white dwarf mergers or tidally shredded ...

Landrace diversity and heritage of the indigenous millet crop fonio (Digitaria exilis): Socio‐cultural and climatic drivers of change in the Fouta Djallon region of Guinea

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
White fonio (Digitaria exilis [Kippist] Stapf) is an understudied millet crop, indigenous to West Africa and cultivated in the region largely through traditional practices. This species is climate‐resilient, fast‐growing, nutritionally rich, and provides livelihoods and food security to rural communities.
