Analysis and compensation of the reflector antenna pointing error under wind disturbance

期刊: RESEARCH IN ASTRONOMY AND ASTROPHYSICS, 2021; 21 (6)

A large reflector antenna has been widely used in satellite communications, gravitational wave detection, galaxy origin observation and other fields d......

Stellar activity cycles as revealed by long-term beat-like patterns from light curves of Kepler

期刊: RESEARCH IN ASTRONOMY AND ASTROPHYSICS, 2021; 21 (6)

Stellar activity cycles have been found on many stars through different methods. Although in debate, an empirical relation has been found where a peri......

Investigating variable stars in the open cluster NGC 1912 and its surrounding field

期刊: RESEARCH IN ASTRONOMY AND ASTROPHYSICS, 2021; 21 (3)

In this work, we studied the variable stars in the open cluster NGC 1912 based on the photometric observations and Gaia DR2 data. More than 3600 CCD f......

Simulation of the orbit and spin period evolution of the double pulsars PSR J0737-3039 from their birth to coalescence induced by gravitational wave radiation

期刊: RESEARCH IN ASTRONOMY AND ASTROPHYSICS, 2021; 21 (4)

The complete orbital and spin period evolutions of the double neutron star (NS) system PSR J0737-3039 are simulated from birth to coalescence, which i......

High-alpha-Metal-Rich stars in the LAMOST-MRS survey and its connection with the galactic bulge

期刊: RESEARCH IN ASTRONOMY AND ASTROPHYSICS, 2021; 21 (6)

We report the detection of a large sample of high-alpha-metal-rich stars on the low giant branch with 2.6 < log g < 3.3 dex in the LAMOST-MRS su......

Exploring the characteristics of the flare from PMN J0218-2307 by Fermi-LAT

期刊: RESEARCH IN ASTRONOMY AND ASTROPHYSICS, 2021; 21 (7)

PMN J0218-2307 (4FGL J0218.9-2305) is classified as a blazar candidate with unknown type (BCU) in the fourth source catalog from the Fermi Large Area ......

A correction method for the telluric absorptions and application to Lijiang Observatory

期刊: RESEARCH IN ASTRONOMY AND ASTROPHYSICS, 2021; 21 (7)

Observing a telluric standard star for correcting the telluric absorption lines of spectrum will take a significant amount of precious telescope time,......

Lunar cratering asymmetries with high lunar orbital obliquity and inclination of the Moon

期刊: RESEARCH IN ASTRONOMY AND ASTROPHYSICS, 2021; 21 (6)

Accurate estimation of cratering asymmetry on the Moon is crucial for understanding Moon evolution history. Early studies of cratering asymmetry have ......

GRB 130310A: very high peak energy and thermal emission

期刊: RESEARCH IN ASTRONOMY AND ASTROPHYSICS, 2021; 21 (3)

The special GRB 130310A was observed by Fermi Gamma-Ray Burst Monitor and Large Area Telescope, with T (90)similar to 2.4 s. With a combination of a B......

The feasibility and flexibility of selecting quasars by variability using ensemble machine learning algorithms

期刊: RESEARCH IN ASTRONOMY AND ASTROPHYSICS, 2021; 21 (4)

In this work, we train three decision-tree based ensemble machine learning algorithms (Random Forest Classifier, Adaptive Boosting and Gradient Boosti......

Predicting the evolution of photospheric magnetic field in solar active regions using deep learning

期刊: RESEARCH IN ASTRONOMY AND ASTROPHYSICS, 2021; 21 (5)

The continuous observation of the magnetic field by the Solar Dynamics Observatory (SDO)/Helioseismic and Magnetic Imager (HMI) produces numerous imag......

A WISE view of IRAS debris disks: revising the dust properties

期刊: RESEARCH IN ASTRONOMY AND ASTROPHYSICS, 2021; 21 (3)

Debris disks around stars are considered as components of planetary systems. Constraining the dust properties of these disks can give crucial informat......

Chempl: a playable package for modeling interstellar chemistry

期刊: RESEARCH IN ASTRONOMY AND ASTROPHYSICS, 2021; 21 (3)

Astrochemical modeling is needed for understanding the formation and evolution of interstellar molecules, and for extracting physical information from......

Design of the cryogenic system of the wideband phased array feed for QTT

期刊: RESEARCH IN ASTRONOMY AND ASTROPHYSICS, 2021; 21 (4)

Phased array feeds (PAFs), which illuminate the dish with digitally synthesized beams instead of separated horns, provide the capability for wider and......

Nereid's orbit based on new precise observations

期刊: RESEARCH IN ASTRONOMY AND ASTROPHYSICS, 2021; 21 (7)

A new orbit of Triton was provided by our previous work, benefitted by new Gaia Data, both in a new precise reduction of charge-coupled device observa......
