While Earth's weather reports center on precipitation, temperature, wind direction and velocity, and humidity, space weather forecasts attempt to predict activity that occurs on the sun -- and how the...
Accretion onto supermassive black holes (SMBHs) in galaxy formation simulations is frequently modelled by the Bondi-Hoyle formalism. Here we examine the validity of this approach analytically and nume...
We use three-dimensional hydrodynamical simulations to study the rapid infall phase of the common envelope interaction of a red giant branch star of mass equal to 0.88 \msun and a companion star of ma...
We investigate NLTE effects for magnesium and calcium in the atmospheres of late-type giant and supergiant stars. The aim of this paper is to provide a grid of NLTE/LTE equivalent width ratios W/W* of...
S-type stars are late-type giants whose atmosphere is enriched in carbon and s-process elements because of either extrinsic pollution by a binary companion or intrinsic nucleosynthesis and dredge-up o...
We present results of high resolution ( 55000) spectral observations of 830 photometrically pre-selected candidate red giants in the magnitude range of V = 9-12. We develop a pipeline for automated d...
A procedure of gridification of the computation of asteroid proper orbital elements is described. The need to speed up the time consuming computations and make them more e±cient is justified by the la...
Binary star formation and mass outflows:Mhd nested grid simulation。
Synthetic ionizing spectra for planetary nebulae:a new grid of metal-line blanketed nlte model atmospheres。
