Solving the mystery of white dwarf’s mass

On Nasa website, it’s possible to find a description of white dwarf. It is said, it is the next step for stars like the Sun after they have exhausted their nuclear fuel. However, Nassim Haramain proposed a different theory according to which stars do not have a simple linear life like current model proposed, but they follow a life cycle starting from an initial black hole and returning to it at the end of this cycle. In fact, this theory is backed up with physical and mathematical equations showed in Nassim paper Scale Unification – A Universal Scaling Law for Organized Matter. But, more important, it agrees with current astronomical observations and is coherent with what is visible in nature where nearly everything is part of a cycle.

Nonetheless, like all new and groundbreaking theory, it is difficult to be accepted by the scientific establishment. But the truth will appear by itself as and when more observations will reveal more details about the nature of the cosmos. Lately, a team of the U.S. Naval Observatory just proves patience is an essential virtue in science.

"Now that the mass from the orbit matches that from the gravitational redshift, this source of consternation has gone away and it is not necessary to invoke other more exotic solutions to the problem. Patience is a virtue."

Dr Mason and his team have just published a paper on a new relative orbit solution with new dynamical masses is determined for the nearby white dwarf - red dwarf pair 40 Eridani BC. By combining the computed orbits with spectrographic data and the stars' nearby location, it was found that the brighter component was a "white dwarf".

"Due to the long period of most visual binaries and the understandable impatience of calculators, orbits are often calculated when they 'can' be and not necessarily when they 'should' be."

Utilizing a technique called "speckle interferometry," Dr. Mason and his colleagues observed 40 Eridani BC over the course of six nights. These complementary observations allowed the team to correct the inconsistency of the masses determined by gravitational redshift and dynamical techniques, due to a premature orbit calculation, and to propose a new calculation for the mass of this white dwarf star.
