Robert Nemiroff has proposed that a gravitational lensing effect utilising it may provide the mass of MACHOs, though this phenomenon is usually an impediment to the resolution of multi-body problems such as the Struve- Sahade effect.
Robert Nemiroff has proposed that a gravitational lensing effect utilising it may provide the mass of MACHOs, though this phenomenon is usually an impediment to the resolution of multi-body problems such as the Struve- Sahade effect. One of the first modern methods for determining it was proposed by Halley, but his method is commonly unsuccessful due to the black drop effect. It may be computed via the exponential of the difference between apparent and absolute magnitude minus 5 over 5, However, it is the method of Bessel, who determined it for 61 Cygni, that remains the standard. For ten points, name this apparent change in a star's position caused by the changing angle subtended by the radius of the earth's orbit at its distance from the star.
