Star destroys the life of its own planet
Man is so lucky that he got a life giving planet like earth. one in the universe. We are the ones who live life with passion. Despite this, the human being is bent on burning it in the hellish fire like global warming. If we compare it with other planets of our solar system, none is like Earth. Now talking about outer exoplanets, how dangerous their life is, new research shows.
Exoplanet means the life of planets outside our solar system is not safe. The planet’s own star burns it to death. This startling revelation has come to the fore from the research done on the scorching planets. This research was done by German scientists on 21 stars regarding the effect of intense solar flares.
This discovery has been published in the Astronomical Society Monthly Science magazine. Most of the stars in our galaxy are considered cool stars. Astronomers classify cool stars as F, G, K or M. Our own star Sun is in G category. Although our Sun is full of intense heat, it is still considered a cold star. Now the best type of stars are M stars ie red dwarf stars. These are present in the largest numbers in our galaxy. Red dwarf stars are extremely active. These emit fierce solar winds. Their intense radiation can be dangerous for any nearby exoplanet. To find out, scientists from the Leibniz Institute for Astrophysics Potsdam (AIP) in Germany studied this phenomenon. It was then discovered that stars with stronger magnetic fields generate more powerful dangerous solar winds, which can strip the atmosphere of any nearby planet. Comparing it to our Sun, ours is considered cool in the category of stars. Despite this, the Earth is always in danger from the solar storm coming from it. To avoid this, solar scientists keep an eye on the Sun for 24 hours. This research is the first systematic characterization of stellar winds in a sample of cold stars. The researchers used numerical simulations with one of the most sophisticated existing models. The large-scale magnetic field distributions of 21 well-observed stars were included in the simulations. The research team used supercomputers at the AIP and the Leibniz Reichenzentrum (LRZ). In which the gravity of stars, strength of magnetic field, various characteristics of stars including rotation period were studied. This research was done on 21 stars.
Still little is known about the world of stars
Solar scientist Dr. Wahabuddin, former director of Aryabhatta Observational Science Research Institute ARIES, says that the world of stars is unique. Their power cannot even be imagined. Actually we know very little about the world of stars. Who does not know the superpower of the universe like black hole, which is made of stars. Therefore, it can be easily guessed that how it can swallow any planet and the new research throws light on this.
