The eclipsing binary 2MASS J04100497+2931023(J04100497+2931023)is classified its spectral type of M0±2V on basis of a low-resolution spectral survey by the Lar
Lucky imaging is a high-resolution astronomical image recovery technique with two classic implementation algorithms,i.e.image selecting,shifting and adding in i
Employing the stellar evolution code Modules for Experiments in Stellar Astrophysics(MESA),we calculate yields of heavy elements from massive stars via stellar
The continuous observation of the magnetic field by the Solar Dynamics Observatory(SDO)/Helioseismic and Magnetic Imager(HMI)produces numerous image sequences i
Flat-field reflects the non-uniformity of the photometric response at the focal plane of an instrument,which uses digital image sensors,such as Charge Coupled D
The Galactic halo is supposed to form from merging with nearby dwarf galaxies.In order to probe different components of the Galactic halo,we have applied the Ga
This paper presents the results of H imaging of 169 galaxies randomly selected from the.40-SDSS catalog.The sample has excluded all low surface brightness galax
Extreme space weather events including≥X5.0 flares,ground level enhancement(GLE)events and super geomagnetic storms(Dst≥-250 nT)caused by super active regions
We present the results obtained from detailed timing and spectral studies of a black hole candidate MAXI J1813-095 using Swift,NICER,and NuSTAR observations dur
