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.
