Philipp Podsiadlowski, in a series of papers well summarized in Morris and Podsaidlowski (2009), shows that the blue supergiant and the rings can be explained as the result of the merger of a 15-20 solar mass primary and a five solar mass secondary, about 20 000 years before the explosion.
At the center of the S106 region is IRS4, a massive star born some 100,000 years ago with a solar mass of about 20 times that of the sun.
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.
The team calculates that about one-hundredth of a solar mass of material was ejected by the gamma-ray burst, some of which was gold.
Figure 1 plots the density of a black hole as a function of its mass in the unit of the solar mass (the solid line) or a function of its radius in the unit of 3 kilometers (the same line).
These more massive stars may also undergo severe mass loss through intense stellar winds--perhaps more than 1 solar mass per billion years.
In this work, a liquid model of the Sun is presented wherein the entire solar mass is viewed as a high density/high energy plasma.
0 solar mass star it will require perhaps 50 million years and for a diminutive star of just 0.
Their average velocity is about 14 percent the speed of light, or about 94 million mph, and the team estimates that the amount of matter required to sustain the outflow is close to one solar mass per year -- comparable to the accretion rate of these black holes.
and the data are used to determine global sea surface wind speed and direction as well as to monitor solar mass ejections from the sun.
The spacecraft supports on-orbit operation of the Naval Research Laboratory's WindSat instrument and the Air Force Research Laboratory's Solar Mass Ejection Imager instrument.
