Soarele intr-un sistem dublu

-----------------------------------

Desi e highly speculative, unele voci sustin ideea ca soarele face parte dintr-un sistem dublu cu lung ciclu. Partenerul Soarelui ar trebui sa fie un corp intunecat: pitica maronie de ex, sau chiar o gaurica neagra care nu se haraneste. Nu cred ca ar fi fost cazul de un partener stea "normala" caci am fi simtit sigur influenta lui.

In mod ironic (atentie Abel :) ), chestia asta se leaga si de precesia aia a ta de care nu mai vreau sa aud  :twisted: 

Anyway, e un subiect interesant ce parere aveti?

Understanding Precession of the Equinox
Evidence our Sun may be part of a long cycle binary system

Walter Cruttenden and Vince Dayes

A recent study of the phenomenon known as &#8220;Precession of the Equinox&#8221; has led researchers to question the extent of lunisolar causation and to propose an alternative solar system model that better fits observed data, and solves a number of current solar system anomalies.

The current (standard) model was theorized before there was any knowledge of the life cycle of stars, or awareness that some stars are non-visible and could thereby exert unseen gravitational influence. The standard model was developed before knowledge of binary prevalence or any understanding of binary star motions. Indeed the idea of a single sun with lunisolar wobble causing precession was originally developed at a time when the Sun had only recently replaced the Earth as the center of the solar system and the Sun was thought to be fixed in space. Consequently, any theory to explain the observed phenomenon of precession of the equinox had to be based solely on movement of the Earth. Although, it has stood for almost 500 years with only minor changes, it fails to answer a number of well-documented solar system anomalies:
# Angular Momentum: Why is there an anomalous distribution of angular momentum in the solar system -- why do the Jovian planets have most of the angular momentum when the Sun has most of the mass?
# Sheer Edge: Why, just beyond the Kuiper Belt, does our solar system seem to have an unusual sheer edge to it? This is surprising for a single sun system.
# Sidereal vs. Solar Time : Why is the delta (time difference) between a sidereal and solar day attributed to the curvature of the Earth's orbit (around the Sun), but the delta between a sidereal "year" and solar year attributed to precession?
# Comet Paths: Why are many comet paths concentrated in a non-random pattern?
# Acceleration of Rate of Precession: Why has the annual precession rate increased over the last 100 years? What would cause it to slow down or speed up?
# Equinoctial Slippage: Lunisolar precession theory would cause the seasons to shift were it not for a concurrent slippage of the equinoctial point around the Earth's orbit path (ecliptic). Lunar cycle equations contradict this motion. Why can't it be explained with the current theory?

All of these questions have been answered in different ways; e.g., angular momentum may have disappeared due to an early solar magnetic force which has also disappeared, the sheer edge may be due to a rogue planet that swept by our solar system in fairly recent times but is now gone, etc. We would like to propose a new model, based on a binary system, which provides a single and greatly simplified solution to all these questions.
