ALMA reveals planet-forming potential of protoplanetary disk
ALMA planet-forming potential protoplanetary disk
2016/2/23
Astronomers struggle to understand how planets form in binary star systems. Early models suggested that the gravitational tug-of-war between two stellar bodies would send young planets into eccentric ...
Joint downscale fluxes of energy and potential enstrophy in rotating stratified Boussinesq flows
Turbulent ows Strati ed ows Rotating ows
2011/10/14
We employ a coarse-graining approach to analyze nonlinear cascades in Boussinesq flows using high-resolution simulation data. We derive budgets which resolve the evolution of energy and potential enst...
We study the hybrid inflationary potential in a regime where the defect field is light, and more than 60 e-folds of accelerated expansion occur after the symmetry breaking transition. Using analytic a...
Potential Biases in the Detection of Planetary Systems with Large Transit Timing Variations
methods: data analysis – planetary systems – planets and satellites: detection –techniques: photometric
2011/9/29
The Transit Timing Variations (TTVs) technique provides a powerful tool to detect additional planets in transiting exoplanetary systems. In this paper we show how transiting planets with significant T...
Inflation with improved D3-brane potential and the fine tunings associated with the model
improved D3-brane potential the fine tunings associated
2011/1/13
We investigate brane-antibrane inflation in a warped deformed conifold background that includes contributions to the potential arising from imaginary anti-self-dual (IASD) fluxes including the term wi...
Nonlinear force-free and potential field models of active-region and global coronal fields during the Whole Heliospheric Interval
Nonlinear force-free potential field models
2011/1/13
Between 2008/3/24 and 2008/4/2, the three active regions NOAA active regions 10987, 10988 and 10989 were observed daily by the Synoptic Optical Long-term Investigations of the Sun (SOLIS) Vector Spec...
The Potential Importance of Non-Local, Deep Transport on the Energetics, Momentum, Chemistry, and Aerosol Distributions in the Atmospheres of Earth, Mars and Titan
Non-Local Deep Transport the Energetics
2011/1/11
A review of non-local, deep transport mechanisms in the atmosphere of Earth provides a good foundation for examining whether similar mechanisms are operating in the atmospheres of Mars and Titan. On E...
Fitting galactic rotation curves with conformal gravity and a global quadratic potential

2010/11/16
We apply the conformal gravity theory to a sample of 110 spiral galaxies whose rotation curve
data points extend well beyond the optical disk. With no free parameters other than galactic mass to ligh...

Galaxies evolution-dark matter-Galaxies halos
2009/1/15
Two-component systems are conceived as macrogases, and the re-
lated equation of state is expressed using the virial theorem for subsystems, under
the restriction of homeoidally striated density pro...
