Variations in pulsar subpulse drift rate

Unusual evolutionary features and complicated characteristics of drifting subpulses have been observed in some pulsars (Wright & Fowler 1981; Smits et al., 2005; Basu & Mitra 2018), described in terms of multiple subpulse drift rates, pr...

Research Progress in the Energy Dissipation of Solar Wind Burst and Particles Acceleration of the Diffusive Shock

Solar Eruption is the origin of the Solar Energetic Particles, and it is also the basic impact factor of the solar-terrestrial environment and the space weather. Coronal Mass Ejections (CME) driven-shock is considered to be the important...

Effects of infall and outflow on massive star-forming regions

Star formation begins with the collapse of dense clumps, and forms much more dense cores in its center. At the same time, outflow driven by the star formation activities in the dense core will take some materials away from the dense core...

Spatial Variation of the Chemical Properties of Massive Star-forming Clumps

Many authors have used molecular lines at millimeter such as N2H+(1–0), HCO+(1–0), HCN(1–0), HNC(1–0) an CN(1-0) to study the evolution of massive star forming regions, and try to find a chemical clock for massive star formation. How...

Carbon isotope ratio in starburst galaxies

Even though interstellar carbon isotope ratios are locally understood, in extragalactic space beyond the Magellanic Clouds they are almost unexplored. We lack information on objects outside the Local Group of galaxies tracing environment...
