Some stars have stellar winds boasting speeds as great as 5 million miles per hour, deeming even their"habitable zone" planets as not so friendly to life.Cool stars with powerful magnetic fields could have stellar winds so harsh they strip away the atmospheres of orbiting planets, making these worlds incapable of hosting life.
"Cool stars," as considered by the team, include stellar bodies divided into four categories: F-type, G-type, K-type and M-type stars. These categories are dependent on size, temperature and brightness. An example of such an interaction is with the auroras created over the Earth's north and south poles. When solar winds strike our planet’s magnetic bubble — the magnetosphere — several processes occur that lead to glowing green patterns in the sky. But the result of stellar wind antics, as it appears, isn't always so pretty.
