IRAS 15398-3359 is a young, small, relatively cool Class 0 protostar, which is an early stage of star formation. The star is located about 47 light years from Earth. It emits weak light, which struggles to penetrate the surrounding cloud of gas and dust. Several studies have been conducted to understand the properties and environment…

Research to be reviewed related to the formation scenarios in these planet formation convections cells processes: Rapid formation of exoplanetesimals revealed by white dwarfs “By simulating planetesimal evolution and collisional evolution, we show that the most likely heat source is short-lived radioactive nuclides such as 26Al (which has a half-life of ~0.7 Myr). Core-rich materials in the…

To what degree is gravity needed to form structures in space? While many believe that celestial bodies (stars, planets, moons, meteoroids) can only form through gravitational attraction in the vacuum of space, I believe that these bodies form through a thermodynamic process similar to the formation of hydrometeors (e.g., hail). This is because our solar…
