Stellar Astrophysics : The Music of Sun ! 1. What does Helioseismology tell us about the sun? 2. Does the sun oscillate? 3. Does the sun produce sound? The Sun resembles an immense melodic instrument. It rings like a chime/bell, and vibrates like an organ pipe, Much the same as a piano has 88 keys … Continue reading Stellar Astrophysics : The Music of Sun ! →

1.The Resilience of Life to Astrophysical Events Abstract: Much attention has been given in the literature to the effects of astrophysical events on human and land-based life. However, little has been discussed on the resilience of life itself. Here we instead explore the statistics of events that completely sterilise an Earth-like planet with planet radii … Continue reading Top physics related Journal papers (2017-18) From Nature →

A review on the analysis and application of RS-25 cryogenic engine used in NASA’s typical space missions – Astrophysics

Posted on by Akshay kumar das in NASA - National Aeronautics and Space Administration

Abstract The cryogenic propulsion technology consists of Liquid Hydrogen (-253°C) and Liquid Oxygen (-183°C). The Newton’s third law of motion is used as a basic principle. This is the only engine that gives 100% efficiency and without any greenhouse gas, vapors emissions. This engine gives a trust of 15000 lb. This thrust can be increased … Continue reading A review on the analysis and application of RS-25 cryogenic engine used in NASA’s typical space missions – Astrophysics →
