The first binary star evolution model producing a Chandrasekhar mass white dwarf
, 2003 Today, Type Ia supernovae are essential tools for cosmology, and recognized as major contributors to the chemical evolution of galaxies. The construction of detailed supernova progenitor models, however, was so far prevented by various physical and ...

Can the rapid braking of the white dwarf in AE Aquarii be explained in terms of the gravitational wave emitter mechanism? [PDF]
, 2002 The spin-down power of the white dwarf in the close binary AE Aquarii significantly exceeds the bolometric luminosity of the system. The interpretation of this phenomenon in terms of the gravitational-wave emitter mechanism has been recently suggested by

Magnetars and white dwarf pulsars [PDF]
International Journal of Modern Physics D, 2016 The anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs) are a class of pulsars understood as neutron stars (NSs) with super strong surface magnetic fields, namely [Formula: see text][Formula: see text]G, and for that reason are known as magnetars.

Locating Traces of Arboreal Beings: Connecting the Tree and the Woodblock
Archaeology in Oceania, EarlyView.ABSTRACT Woodblocks for printmaking are multi‐perspectival communicators inscribed with layered narratives. The artistic process of cutting excavates the surface of a woodblock, making visible lesser‐seen traces of the past, reflective of the practice of archaeology.

Essential work, invisible workers: The role of digital curation in COVID‐19 Open Science
Journal of the Association for Information Science and Technology, Volume 76, Issue 4, Page 703-717, April 2025.Abstract In this paper, we examine the role digital curation practices and practitioners played in facilitating open science (OS) initiatives amid the COVID‐19 pandemic. In Summer 2023, we conducted a content analysis of available information regarding 50 OS initiatives that emerged—or substantially shifted their focus—between 2020 and 2022 to address ...

Nuclear Mixing Meters for Classical Novae [PDF]
, 2013 Classical novae are caused by mass transfer episodes from a main sequence star onto a white dwarf via Roche lobe overflow. This material forms an accretion disk around the white dwarf.

To Tell or Not to Tell? On the Under Communicating of Sustainability in Digital Environments
Business Strategy and the Environment, EarlyView.ABSTRACT The paper investigates sustainability communication using digital tools—such as social media, websites, emails, and newsletters—and delves into the drivers that determine the undercommunication of sustainability (i.e., the green blushing phenomenon) in digital environments.

Revisiting the Impact of Axions in the Cooling of White Dwarfs
, 2012 It has been shown that the shape of the luminosity function of white dwarfs can be a powerful tool to check for the possible existence of DFSZ-axions. In particular, Isern et al.
