Don't be
fooled by its pixelated look. A set of young stellar twins circle each other in
this infrared image.
Weighing more
than 10 times the mass of the Sun altogether, these two stars sit about 5,000
light-years away toward the constellation Cygnus. Researchers believe the stars
are relatively young – only 100,000 years old – and make up the youngest
massive binary system ever observed directly.
In this
infrared view, the higher-mass primary star appears as the pink spot at the
center, with its lower-mass companion showing as the green spot to the lower
right.
The
blue-white spots at the upper right and left in this image are holes cleared in
the system’s surrounding circumstellar disk by outflow from the young star
system. The presence of the disk, which itself contains about one-tenth the
mass of the Sun or about 100 Jupiter masses, suggests that massive binary
systems form by accreting material much like the Sun.
Astronomers
with the Harvard-Smithsonian Center for Astrophysics used the UKIRT Telescope
atop Hawaii’s Mauna Kea to observe the stellar pair in the infrared range of
the light spectrum.
