The X-ray luminosity function of short gamma-ray bursts

期刊: ASTROPHYSICS AND SPACE SCIENCE, 2021; 366 (4)

We present for the first time the X-ray luminosity function of short gamma-ray bursts (sGRBs) estimated from 22 Fermi sGRBs. We find that the cumulati......

The midrange periodicities of solar Ha flare index during Solar Cycles 21-24

期刊: ASTROPHYSICS AND SPACE SCIENCE, 2021; 366 (7)

The temporal and spatial variations of solar magnetic activity indices in the various atmospheric layers are important for understanding and revealing......

Investigation and application of fitting models for centering algorithms in astrometry

期刊: ASTROPHYSICS AND SPACE SCIENCE, 2021; 366 (6)

To determine the precise positions of stars in CCD frames, various centering algorithms have been proposed for astrometry. The effective point spread ......

MHD simulations of the Kelvin-Helmholtz instability near the ionopause of Venus across a range of density ratios and magnetic Reynolds numbers

期刊: ASTROPHYSICS AND SPACE SCIENCE, 2021; 366 (8)

The Kelvin-Helmholtz instability on the ionopause of Venus with different density ratios and magnetic Reynolds numbers has been simulated numerically ......

Analysis of ionosphere response during high-speed solar wind stream in early August 2020

期刊: ASTROPHYSICS AND SPACE SCIENCE, 2021; 366 (8)

Ionosphere parameters obtained from International Global Navigation Satellite System (GNSS) Service (IGS) stations and SWARM satellites were used to a......

Wavelength dependent transit depth of HATS-5b: a haze dominant atmosphere?

期刊: ASTROPHYSICS AND SPACE SCIENCE, 2021; 366 (8)

The wavelength-dependent transit depth indicates the atmosphere composition of an exoplanet. We analyze the transit depth of HATS-5b using the data fr......

A simulated gravity field estimation for the main belt comet 133P/Elst-Pizarro

期刊: ASTROPHYSICS AND SPACE SCIENCE, 2021; 366 (6)

The Main Belt Comet 133P/Elst-Pizarro is one of the targets in China's asteroid exploration mission. To support this goal, gravity field estimation fo......

The transfers from lunar DROs to Earth orbits via optimization in the four body problem

期刊: ASTROPHYSICS AND SPACE SCIENCE, 2021; 366 (6)

The distant retrograde orbits (DROs) can serve as the parking orbits for a long-term cis-lunar space station. This paper gives a comprehensive study o......

Calibration and parameter corrections for the new generation of the TSI monitor on the FY-3E satellite

期刊: ASTROPHYSICS AND SPACE SCIENCE, 2021; 366 (3)

In order to support the analysis of potential long-term trends in the Sun's variability and trace the WRR ground calibration ratio to the measurement ......

Bifurcation analysis and approximate analytical periodic solution of ER3BP with radiation and albedo effects

期刊: ASTROPHYSICS AND SPACE SCIENCE, 2021; 366 (3)

The nonlinear dynamics of an elliptic restricted three-body system with perturbations such as radiation and albedo are studied in this paper. The effe......

The influence of tesseral harmonic J(22) term on the TLE orbit error of low polar orbit satellite

期刊: ASTROPHYSICS AND SPACE SCIENCE, 2021; 366 (1)

By expanding the perturbation function of tesseral harmonic J(22) term of the earth's non spherical gravitation, it is found that there is a term cos2......

A homotopy approach connecting time-optimal with fuel-optimal trajectories

期刊: ASTROPHYSICS AND SPACE SCIENCE, 2021; 366 (1)

This paper describes a novel homotopy method to compute fuel-optimal trajectories starting from a time-optimal solution. The time-optimal problem is p......
