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.

A search for the presence of magnetic fields in the two Supergiant Fast X-ray Transients IGR J08408-4503 and IGR J11215-5952 [PDF]

, 2017
A significant fraction of high-mass X-ray binaries are supergiant fast X-ray transients (SFXTs). The prime model for the physics governing their X-ray behaviour suggests that the winds of donor OB supergiants are magnetized.

Adaptability in Innovation Management: A Meta‐Analysis

Journal of Product Innovation Management, EarlyView.
ABSTRACT Academic Summary As firms navigate dynamic technological, market, and institutional environments, adaptability—and related notions such as flexibility and agility—have become central to innovation management. Yet, the literature is conceptually fragmented: multiple labels are applied with overlapping but inconsistent content, and few studies ...

The long-period Galactic Cepheid RS Puppis - II. 3D structure and mass of the nebula from VLT/FORS polarimetry

, 2012
The long-period Cepheid RS Pup is surrounded by a large dusty nebula reflecting the light from the central star. Due to the changing luminosity of the central source, light echoes propagate into the nebula.

Elevation, rather than land use, causes important dietary shifts in the Mediterranean golden eagle

Journal of Zoology, EarlyView.
In an ever‐changing landscape, golden eagles in the Iberian Peninsula demonstrate remarkable dietary adaptability. We monitored 50 distinct breeding events over 4 years using camera traps, collecting over 520 000 images. Elevation, rather than land use, emerged as the main driver of prey composition: lagomorphs and columbiforms dominated at lower ...

Marécages, une pollution par essence? Conditions d'une écopoétique des marais et autres zones humides au XXe siècle

Orbis Litterarum, EarlyView.
Abstract To expose the pollution of marshes and swamps, whether by hydrocarbons or other contaminants, the French or Francophone author of the twentieth century must first confront a literary tradition that equates stagnant water with a volatile poison and, more broadly, wetlands with toxic environments. In his article “Wetland Gloom and Wetland Glory,”
