| Expected & Detected X-ray emission from the outer atmospheres, or coronas, of stars of almost every type: young and old, large and small. Unexpected Detection of X-ray flares from brown dwarfs, or failed stars. This discovery provides a new way to study how the magnetic field changes on low-mass stars as they age. |
Unexpected Chandra observations of massive stars suggest that some of these stars may not be losing nearly as much mass in strong winds flowing away from the stars as previously thought. Unexpected Radiation from a single massive star has triggered the formation of hundreds of new stars. |
Unexpected Flares from very young stars are much more frequent and intense than on the present-day Sun, and may actually aid the formation of planets around these stars |
Unexpected Evidence that the X-ray emitting hot gas from planetary nebulas comes from deep within a Sun-like star that has neared the end of its evolution and will soon become a white dwarf. |
