"Rapid Weight Loss: Sun-like Stars Shed Pounds Due to Powerful Stellar Winds"

Astronomers have detected stellar winds blowing from three main-sequence stars similar to the sun, finding that these winds shrink about 67 times as fast as the sun's. These powerful winds can trigger processes that evaporate the atmospheres of planets orbiting these stars, affecting their potential habitability. The observation of X-rays emitted by the stars' hot plasma bubbles has provided crucial insights into the rates at which these stars lose mass via their stellar winds, shedding light on planetary system evolution and the likelihood of habitable planets.

White Dwarf Transforms into Massive Diamond in Space

Astrophysicists have found a white dwarf in the process of crystallizing, which will help them understand how and when this phenomenon occurs. The white dwarf is in a system with other main-sequence stars, making it easier to determine its age. The researchers estimate its age to be 7.3 billion years, but they say it could be an underestimation. The white dwarf is the first confirmed crystallizing white dwarf in a Sirius-like system, and its location in a system with other stars will make it easier to study white dwarf crystallization.
