Studying the UV Mg II Resonance Lines in 20 Be Stars

Open Astronomy, 2011
Using the GR model, we analyze the UV Mg II resonance lines in the spectra of 20 Be stars of different spectral subtypes, in order to detect the presence of satellite or discrete absorption components. The values of some physical parameters – rotational,

Analysis of mass-transferring binary candidates in the Milky Way

Astronomy & Astrophysics
Mass transfer between stars in binary systems profoundly impacts their evolution, yet many aspects of this process–especially the stability, mass loss, and eventual fate of such systems–remain poorly understood.

Comparison of individual versus ensemble wind farm parameterizations inclusive of sub-grid wakes for the WRF model

, 2022
Wind turbine wakes can be predicted somewhat accurately with mesoscale numerical models, such as the Weather Research and Forecast (WRF) model, via a wind farm parameterization (WFP) that treats the effects of the wakes, which are sub-grid features, on ...
