Numerical Study on Effects of High-Frequency Arrayed Energy Deposition on Scramjet Combustor Performance [PDF]
For the supersonic flows have large momentum, it is difficult to get higher penetration depth because of the influence of transverse jet on incoming flow so as to affect the mixing and combustion efficiency of jet in scramjet combustor.

VELOcities of CEpheids (VELOCE) [PDF]
We present the first data release of VELOcities of CEpheids (VELOCE), dedicated to measuring the high-precision radial velocities (RVs) of Galactic classical Cepheids (henceforth, Cepheids). The first data release (VELOCE DR1) comprises 18 225 RV measurements of 258 bona fide classical Cepheids on both hemispheres collected mainly between 2010 and 2022,

Oscillatory Modes оf the Atmosphere оf Jupiter аnd Venus
Introduction. The article studies the oscillatory modes of the atmosphere of two planets (Jupiter, Venus), taking into account the influence of axial rotation, which affects the occurrence of beating and resonance, and comparing their parameters with the
