The first direct measurement revealed the object to be a 40-billion solar mass
This lead to the conclusion that the mass of the Milky Way is 1.5 trillion solar masses
. A solar mass
is the standard unit of mass in astronomy, which equals approximately 2A1030 kg.
The Milky Way weighs in at about 1.5 trillion solar masses
(one solar mass
is the mass of our Sun), according to the latest measurements.

These more massive stars may also undergo severe mass loss through intense stellar winds--perhaps more than 1 solar mass
per billion years.
Found within two young star clusters, NGC 3603 and RMC 136a, the stars weigh up to 300 times the mass of the Sun, a figure which doubles the previously accepted limit of solar mass
The several hundred faint young objects are seen to have recently emerged at the tip of the Northern Cross with a solar mass
of around less than eight hundredths, it said.
The O-V model is not quite realistic because it considers the neutrons as a Fermi gas; however, no matter which model is considered, all the models predict a limit to the mass because of the singular metric, while it will be shown that in a nonsingular metric even the O-V model, that otherwise gives the sharper limit to the mass ([approximately equal to] 0.7 of solar mass
), does not show it, instead it gives the equilibrium radius for any value of the mass.
For example, to reach this stage, it will take a star of around 5.0 solar masses
something like 500,000 years but for a 1.0 solar mass
star it will require perhaps 50 million years and for a diminutive star of just 0.3 solar masses
the period will extend to over 100 million years.
Prof George Simnett said the pictures of so-called solar mass
ejections had been taken with equipment developed and built at the university and sent into space.
The researchers also found that in regards to massive black holes with a solar mass
of 100 million or less, there is no correlation between the black-hole mass and the galaxy distribution.
I did not take the proposed black hole mass for M but used one solar mass
instead as a reference.
