The intermediate mass
objects all lie within a 1,500-light-year distance from the sun, but that is because they are very faint and difficult to observe at greater distances.
Among specific topics are clumping in massive star winds and its possible connection to the B[e] phenomenon, the evolution of intermediate mass
and massive binary stars, massive stars evolved towards the Wolf-Rayet stage, the long-term photometric monitoring of objects with the B[e] phenomenon, and ultraviolet variability in B[e] stars.
Are there intermediate mass
black holes in the Galactic center?
Astronomers have discovered what appears to be a black hole of intermediate mass
in the arm of NGC 2276, a spiral galaxy 100 million light-years from Earth.
The birth of planetary nebulae, resulting from the death of low and intermediate mass
stars, is usually thought of as a slow process, in contrast with the intense supernovae that massive stars produce.
This new work, led by Grzegorz Pietrzynski of the Universidad de Concepcion in Chile and Warsaw University Observatory in Poland, used 16-years-worth of observations to identify a sample of intermediate mass
binary stars with extremely long orbital periods, perfect for measuring precise and accurate distances.
Abstract: Low and intermediate mass
stars have initial masses less than about 8 MSUN.
It could be an exotic object such as a pulsar, mini-quasar, supernova remnant or an intermediate mass
Anderson detected a particle of intermediate mass
, the muon (see 1937), but it lacked the necessary properties to fulfill the role Yukawa had laid out for it.
If that is the case, this is the first detection of an intermediate mass
black hole," the National Astronomical Observatory of Japan, which operates the Nobeyama radio telescope that was used to make the detection, said, in the (http://www.
Either a stellar mass black hole was accreting at extreme rates or there was a new subspecies of intermediate mass
black holes accreting at lower rates.
Mushotzky and Tod Strohmayer (also at NASA/Goddard) found that M82 X-1's quasi-periodic behavior stretches over long intervals, indicating an intermediate mass
for the black hole.
