This work interrogates one of the most fundamental and important problems in astrophysics --- namely, the radiation problem thought to bedevil massive stars in their effort to accumulate more mass beyond ten solar masses. Current star formation wisdom holds that at about ten solar masses, the radiation emanating from the nascent massive star aught to halt and ultimately reverse the in-fall of matter onto the nascent massive star. Using Larson (1982, 1981)'s embellished empirical laws, we demonstrate that the gravitational force emanating from the circumstellar material surrounding the nascent ...
This work interrogates one of the most fundamental and important problems in astrophysics --- namely, the radiation problem thought to bedevil massive stars in their effort to accumulate more mass beyond ten solar masses. Current star formation wisdom holds that at about ten solar masses, the radiation emanating from the nascent massive star aught to halt and ultimately reverse the in-fall of matter onto the nascent massive star. Using Larson (1982, 1981)'s embellished empirical laws, we demonstrate that the gravitational force emanating from the circumstellar material surrounding the nascent star is sufficient to overcome the supposed radiation problem. That is to say, with respect to Larson (1982)'s empirical law, we consider the ensuring dynamics between the gravitational force due to the circumstellar material around the nascent massive star and the radiation force emanating from it, and from this consideration, regarding the plausible origins of these laws, we find an excellent agreement between theory and observations. This excellent agreement between theory and observations strongly points to a dynamical origin of Larson (1982)'s empirical law.
