Tired Light and Type ia Supernovae Observations

Authors: Herman Holushko
Comments: 17 Pages.

The phenomenon known as “supernova timescale stretching” was discovered by measuring the observed light curve broadening and by measuring the rate of spectra evolution (aging) for Type Ia supernovae. In modern cosmology this phenomenon is widely considered as one that rules out the “tired light” hypothesis. The redefined “tired light” hypothesis presented in this paper not only agrees with the supernova timescale stretching but actually explains it without employing universe expansion. Using Type Ia supernova spectra template, I have conducted a computer simulation study of light propagation from a supernova to an observer based on the tired light assumptions. The results of the simulation for “at rest” UBVRIYJHK bands do not contradict the astronomical observations related to light curve broadening and spectra aging.

Yarkovsky Effect in Modified Photogravitational 3-Bodies Problem

Authors: Sergey V. Ershkov
Comments: 10 Pages. AMS Subject Classification: 70F15, 70F07. Key Words: Yarkovsky effect, YORP-effect, photogravitational restricted three body problem, stability, equilibrium points, libration points, oblateness

Here is presented a generalization of photogravitational restricted 3-bodies problem to the case of influence of Yarkovsky effect (or more general, YORP-effect). Asteroid is supposed to move under the influence of gravitational forces from 2 massive bodies, as well under the influence of pressure of light from both the primaries. It is proved the existence of maximally 256 different non-planar equilibrium libration points when the 2-nd primary is non-oblate spheroid.
