Abstract
It is known that most stars lose matter in the form of stellar wind. A thermal mechanism for mass loss at chromospheric temperatures is impossible. But it is from the surface of the chromosphere that the accelerated movement of one hundred million tons of gases in the form of spicules begins, reaching speeds of 150 km/s and heating up to a million degrees at the base of the corona. The coronal temperature makes the thermal contribution significantly significant, but still insufficient. Comparison The comparison of the calculated mass loss rate in the tails of the distribution function with the observed values for increasing mass main sequence stars, even for coronal temperatures, indicates an increasing excess of actual mass loss over the gravitational limit. This demonstrates the presence of a non-thermal mechanism for particle acceleration above the photosphere. Regardless of particle acceleration mechanisms such as radiation pressure, MHD, anomalous strong ambipolar diffusion mechanism or Coulomb acceleration, All of them operate outside the hydrostatic model. All stars exhibiting a consistently high mass loss rate exceeding gravitational confinement can be classified as nonrelativistic white holes. Unlike relativistic white holes, a nonrelativistic white hole loses matter from its surface due to the hyperthermal acceleration of atoms above the photosphere.
