In 2016 the leading center of Russian ground-based observational astronomy, the Special Astrophysical Observatory of the Russian Academy of Sciences, celebrated its 50th anniversary. As part of the anniversary celebration, the Observatory organized a conference to discuss a broad range of topics related to the astrophysics of stars and star systems, which brought together the leading experts from Russia, the Russian Commonwealth, and our foreign colleagues. The main idea of the meeting is reflected in its name: the life of a star from its birth (molecular cloud collapse) to death (supernova core collapse). The result of the conference is the present volume containing the latest achievements of the Russian astronomical community in stellar astrophysics, obtained both with domestic instruments and as part of international cooperation. This volume presents recent results of the studies of star-forming regions and the interstellar medium, stellar atmospheres and magnetism, activity of stars, multiple stellar systems and exoplanets, and stars after the nuclear burning stage. Methods and instruments of present-day stellar astrophysics are also discussed.

The interaction of the supersonic gas jet from a young star with the surrounding interstellar medium is studied. Based on the law of energy conservation, simple estimates for the jet and ambient medium parameters in the region of their interaction are obtained. These estimates agree with the observational data for such regions. ...

The process of the plasma ejection formation from the accreting neutron star is investigated. Magnetocavitation model of this process is suggested. According to this model, the plasma ejection is produced because of the magnetospheric destruction associated with the processes of the neutron star quake, resonant interaction of magnetosphere with the accreted plasma and actions of ...

This paper investigates the theoretical limits of object detection within isotropic scattering media using single-photon lidar. Within a simplified model, we derive the fundamental relationship between the maximum attainable detection range and the required photon count per pulse. Two distinct limiting regimes are analyzed: the ballistic photon regime, which maintains high spatial resolution but necessitates ...

background, which occurs due to the anisotropy of the radiation when it is scattered by hot plasma of
galaxy clusters. Detection of this anisotropic Sunyaev-Zel’dovich effect would enable an independent

Dirty superconducting films with magnetic impurities can exhibit nontrivial behavior in a magnetic field that
polarizes the impurity spins. As predicted by Kharitonov and Feigelman (KF) [JETP Lett. 82, 421 (2005)],
this polarization reduces the exchange scattering rate. Consequently, a parallel magnetic field can enhance
the critical temperature Tc when magnetic-field pair breaking is weak, as realized for ...

Colloidal semiconductor nanocrystals have emerged as promising materials for next-generation light-emitting diodes (LEDs) owing to their solution processability, tunable emission wavelengths, narrow emission linewidths, and high photoluminescence quantum yields. Among them, anisotropic nanocrystals, including one-dimensional nanorods (NRs) and two-dimensional nanoplatelets (NPLs), offer additional opportunities for controlling transition dipole moment orientation and light out-coupling efficiency. These ...

A semi-implicit unstructured operator-difference scheme for three-dimensional self-gravitating flows
Kondratyev I., Moiseenko S., Journal of Physics: Conference Series 2021 Vol. 2028 No. 1 Article 012007
A support operators (operator-difference) method has proven itself well for implicit simulations of different astrophysical fluid flows. Following the operator-difference approach, we construct nodal difference analogues of differential operators in Cartesian coordinates, where the conjugacy properties are the same as for original ones. Using the difference operators, we develop an Eulerian semi-implicit gas-dynamical solver with ...
