The Casimir free energy of peptide films on a silicon substrate: Impact of dielectric-to-metal transition in silicon and nanoparticles in peptide
G. L. Klimchitskaya, V. M. Mostepanenko
Using the Lifshitz theory of the van der Waals and Casimir forces, we calculate the Casimir free energy of thin peptide films deposited on silicon substrates. The Casimir free ener…
Estimation of black hole spins in low-mass AGNs and comparison with other types of AGNs
M. Yu. Piotrovich, S. D. Buliga, T. M. Natsvlishvili
We estimated the spins of a sample of 58 low-mass AGNs. Analysis of the obtained spins showed that they decrease with increasing SMBH mass, leading us to hypothesize that mergers a…
TOI-6884b: A low-mass brown dwarf transiting a slightly evolved star
Akanksha Khandelwal, Shubhendra Nath Das, Rishikesh Sharma +42
We report the discovery of a low-mass transiting brown dwarf orbiting TOI-6884 (TIC~156514476, ) from NASA's \textit{Transiting Exoplanet Survey Satellite} (\text…
Role of the Casimir force in the capacitive radio-frequency microelectromechanical switches
G. L. Klimchitskaya, A. S. Korotkov, V. V. Loboda +1
We determine the role of the fluctuation-induced Casimir force acting between a membrane of cylindrical shape and a bottom electrode in microelectromechanical capacitive switches.…
Veiling of Photosphere Lines in the Spectra of UX ORI Stars at Deep Light Minima. I. The Star RR Tau
P. O. Dimitrieva, L. V. Tambovtseva, V. P. Grinin
The spectra of RR Tau star, which belongs to the family of young irregular variable UX Ori type stars, in its different brightness states have been studied using a comparative anal…
Analysis of the Space Velocities of Several Samples of Open Star Clusters
Vadim V. Bobylev, Anisa T. Bajkova
An analysis of the kinematics of open star clusters (OSCs) using their characteristics from the new Hunt and Reffert catalog was conducted. Based on 4003 OSCs younger than 200 mill…
