Explanation:
SS433
is one of the most exotic star systems known. Its unremarkable
name stems from its inclusion in a catalog of stars which emit
radiation characteristic of atomic hydrogen.
Its very remarkable behavior stems from a compact object, a black hole
or neutron star,
which has produced an accretion disk with jets. As illustrated
in this artist's vision
of the SS433 system
based on observational data,
a massive, hot star (left) is locked in a mutual orbit with a
compact object. Material transfers from the massive star into
an accretion disk surrounding the
compact object blasting out two jets of ionized gas in opposite
directions - at about 1/4 the speed of light!
Radiation from the jet tilted toward the observer is blueshifted,
while radiation from the jet tilted away is redshifted.
The binary system itself completes an orbit in about 13 days while
the jets precess (wobble like a top) with a period of about 164
days. Are the jets from SS433 related to those from black
holes at the centers of galaxies?
