The Gum Nebula is a faint supernova remnant extending about 40°across the southern sky,potentially affecting tens of background pulsars.Though the view that the Gum Nebula acts as a potential scattering screen for ba...
Since soon after the discovery of radio pulsars in 1968,their scintillation due to multi-path scattering in the interstellar medium(ISM)emerged as a useful tool in studying the ISM.For example,a recent study with the ...

I analyze a new X-ray image of the youngest supernova remnant(SNR)in the Galaxy,which is the type Ia SNR G1.9+0.3,and reveal a very clear point-symmetrical structure.Since explosion models of type Ia supernovae(SNe Ia...
It is verified that the Nebula Hypothesis is applicable to the Solar System by way of a straightforward generalization of Kepler’s third law which also confirms that angular momentum transport is achieved by way of t...
The extremely accurate estimates of stellar variability and radial velocity in the Gaia Data Release 3(Gaia DR3)have enabled us to examine the close binarity and radial velocity(RV)of central stars(CSs)of planetary ne...
