Roche Lobe Sizes in Deep-MOND Gravity
MOdified Newtonian Dynamics (MOND) is evolving from an empirical to a decent theory respecting fundamental physics after Bekenstein (2004) showed that lensing and Hubble expansion can be modeled rigourously in a Modified Relativity. The degeneracy of MOND with Dark Matter can be broken if we examine the non-linear MONDian Poisson’s equation in detail. Here we study the effect of tides for a bin...
متن کاملRoche Lobe Overflow from Dwarf Stellar Systems
We examine the evolution of residual gas within tidally-limited dwarf galaxies and globular clusters. In systems where the gas sound speed exceeds about 10% of the central velocity dispersion, hydrostatic equilibrium causes the gas to have significant density at the tidal radius. In contrast to the stellar component, gas particles relax rapidly in response to mass loss. Gas lost through the Lag...
متن کاملRoche Lobe Shapes for testing MOND-like Modified Gravities
Dark Matter (DM) theories and mass-tracing-light theories like MOND are by construction nearly degenerate on galactic scales, but not when it comes to the predicted shapes of Roche Lobes of a two-body system (e.g., a globular cluster orbiting a host galaxy). We show that the flattening of the Roche lobe is sensitive to the function μ(g) in modification of the law of gravity. We generalise the a...
متن کاملDirect diameter measurement of a star filling its Roche Lobe
Context. Stellar evolution in close binary systems is strongly influenced by mass transfer from one star to the other when one component fills its zero-velocity surface or Roche Lobe. SS Lep is a fairly nearby close binary showing the Algol paradox and a shell spectrum, both indicative of (past) mass transfer. Aims. To study the process of mass transfer and its evolutionary consequences, we aim...
متن کاملCalculator for Fuzzy Numbers
This paper has been discussed and reviewed two R packages FuzzyNumbers and Calculator.LR.FNs. These packages have the ability of installation on R software, and in fact they propose some useful instruments and functions to the users for draw and easily using arithmetic operators on LR fuzzy numbers. For the convenience of the readers, the proposed methods and functions have been presen...
