Some red dwarf stars will live trillionsof years before they run out of fuel.Then why are red dwarf stars red? Because reddwarf stars only burn a little bit of fuel at a time. Theyare not very hot compared to other stars. Think of afire. The coolest part of the fire at the top of...
They compared each one to the sun in terms of surface temperature, size and rotation. They found that on average, the other stars had five times more brightness variability than our sun.”(与其他类似的恒星相比,太阳在亮度和强度上的变化要少得多。研究人员上周报告了他们对369颗恒星的检测结果。
Although the Sun is quite near to us compared with other stars, it has always kept intriguing and fundamental scientific secrets from us. For instance, we still don’t know how the solar corona — the Sun’s outermost atmosphere — maintains temperatures in excess of one million kelvin, ...
Researchers reported last week on their examination of 369 stars. They compared each one to the sun in terms of surface temperature, size and rotation. They found that on average, the other stars had five times more brightness variability than our sun. ...

Planets orbiting close to hot stars experience intense extreme-ultraviolet radiation, potentially leading to atmosphere evaporation and to thermal dissociation of molecules. However, this extreme regime remains mainly unexplored due to observational challenges. Only a single known ultra-hot giant planet, KE...
