The outer atmosphere of the Sun is observed to be a very hot plasma medium. Since the frequency of electromagnetic wave emission from a plasma medium depends on the electron number density, high frequency radio waves ...

The Mauritius Radio Telescope (MRT) has been used to observe some Southern Hemisphere pulsars at 151.6 MHz. A tracking system allowing observation of a source for 8 x sec (δ) minutes of time and a Fast Data Acquisition ...

The thesis is mainly focused on the modeling of pulsar radio emission and polarization. The radio emission mechanism of pulsar is not fully understood, because of the lack of understanding about the kinematical processes ...

Ever since their discovery, pulsars have been proved to be excellent tools to study the Interstellar Medium. Results from new observations using the Ooty Radio Telescope at 327 MHz are used to investigate the properties ...

We give a brief account of various observational data about pulsars, of some of the conclusions one can derive from these data, about the nature of the pulsars, and in particular, of the properties of the binary pulsar PSR ...

Observations on the pulsation pattern in the time profile of short duration solar radio bursts at decametre wavelengths are presented. The pulsations are found to be present predominantly in the saturation phase of the ...

A method of finding physical parameters by studying the pulses in the sun is discussed. Consideration is given to an ideal highly relevant model which could exist in the sun with the effects of ionization, due to which ...

HD 179821 is classified as G5 Ia star. From the IRAS colors and spectral energy distributions it was classified as a post-AGB star. But some studies classify it as a massive (30 to 19 M⊙) post-red supergiant evolving to ...

What is habitability? Can we quantify it? What do we mean under the term habitable or potentially habitable planet? With estimates of the number of planets in our Galaxy alone running into billions, possibly a number greater ...
