ALMA reveals unusual composition of interstellar comet 2I/Borisov.
We present the first results of the application of the recently found universality of behavior of muon signal to electromagnetic (EM) signal ratio with respect to the vertical depth of showers maximum...
We re-examine the recombination/collisional emission line (RL/CEL) nebular abundance discrepancy problem in the light of recent high-quality abundance determinations in young stars in the Orion star-f...
First results of our 3D numerical simulations of thermohaline convection driven by 3He burning in a low-mass RGB star at the bump luminosity are presented. They confirm our previous conclusion that th...
Evolution of grain mantles in various interstellar environment is studied. We concentrate mainly on water, methanol, carbon di-oxide, which constitute nearly 90% of the grain mantle. We investigate ho...
We present new data on Cherenkov light observations obtained during the period 1994-2009, after a modernization of the Yakutsk EAS array. A complex analysis of $\xmax$ and its fluctuations $\sigma(\xm...
Chemical composition in fast rotators main sequence stars。
The chemical composition of the galactic H II regions M8 and M17. A revision based on deep vlt echelle spectrophotometry。
Photoionization models for planetary nebulae with inhomogeneous chemical composition
Chemical composition of globular cluster and halo post-agb stars。
Chemical composition of planetary nebulae:including iso results。
Physical parameters and chemical composition in abell 78。
This contribution presents the unique technique of using rock pushing activities to estimate the densities of rocks remotely.
