We suggest that the mass lost during the evolution of very massive stars may be dominated by optically thick, continuum-driven outbursts or explosions, ins... N Smith,SP Owocki - 《Astrophysical Journal Letters》 被引量: 200发表: 2006年 A Possible Origin of the Mass–Metallicity Relation of...
tion frequency indicative of the afterglow shock wave moving in a dense medium. Our broadband modeling favors a constant density profile for the circumburst medium over a wind-like profile (R −2 ). However, keeping in mind the uncer- ...
Using optically detected magnetic resonance (ODMR), the divacancy spin spectra in silicon carbide are explored, with a particular focus on varying magnetic field orientations. The contrast observed in ODMR diminishes as the off-axis magnetic field intensity amplifies. Our subsequent investigation focused...
Imagine rays of light striking a distinct boundary separating an optically less dense medium. A less dense medium is the one with a lower reflection index. At an appropriate incidence angle, these rays rather than passing through will be reflected fully. This phenomenon is referred to as the ...
