VY Canis Majoris: The Astrophysical Basis of Its Luminosity [PDF]
arXiv, 2006 The luminosity of the famous red supergiant VY CMa (L ~ 4 - 5 x 10e5 Lsun) is well-determined from its spectral energy distribution and distance, and places it near the empirical upper luminosity limit for cool hypergiants. In contrast, its surface temperature is fundamentally ill-defined.

Monitoring GPS‐collared moose by ground versus drone approaches: efficiency and disturbance effects
Wildlife Biology, EarlyView.Efficient wildlife management requires precise monitoring methods, for example to estimate population density, reproductive success, and survival. Here, we compared the efficiency of drone (equipped with a RGB camera) and ground approaches to detect and observe GPS‐collared female moose Alces alces and their calves. We also quantified how drone (n = 42)

ORFEUS-SPAS II EUV Spectroscopy of epsilon Canis Majoris (B2 II) [PDF]
arXiv, 1997 We report on extreme-ultraviolet (EUV) spectroscopic observations of the B bright giant epsilon Canis Majoris made during the ORFEUS-SPAS II mission. We assess the performance of the instrument in the EUV and find that the effective area is roughly 3 times that of the Extreme-Ultraviolet Explorer (EUVE) long-wavelength spectrometer and that the ...

Unraveling the impact of dog‐friendly spaces on urban–wildland pumas and other wildlife
Wildlife Biology, EarlyView.As the most widespread large carnivore on the planet, domestic dogs Canis lupus familiaris can pose a major threat to wildlife, even within protected areas (PAs). Growing human presence in PAs, coupled with increasing pet dog ownership underscores the urgency to understand the influence of dogs on wildlife activity and health.

Wildlife Biology, EarlyView.Many populations of species belonging to the order Crocodilia are threatened due to illegal trafficking, indiscriminate hunting, and habitat loss and degradation affecting crocodilian health and parasitic load. Although several studies have revealed that crocodiles, caimans, and alligators are frequently infected by Hepatozoon spp., the results from ...

Prototyping and Test of the "Canis" HTS Planar Coil Array for Stellarator Field Shaping [PDF]
arXivThea Energy, Inc. is currently developing the "Eos" planar coil stellarator, the Company's first integrated fusion system capable of forming optimized stellarator magnetic fields without complex and costly modular coils. To demonstrate the field shaping capability required to enable Eos, Thea Energy designed, constructed, and tested the "Canis" 3x3 ...

Wildlife Biology, EarlyView.Recreational activities have been shown to induce fear responses in carnivores, causing both spatial and temporal displacement that can have cascading effects on the wider ecological community. Cougars Puma concolor are one species that are particularly sensitive to human disturbances as they have been found to be impacted by various forms of ...
