Two phase, inward-then-outward migration of Jupiter and Saturn in the gaseous Solar Nebula
accretion, accretion disks – planets and satellites: formation – hydrodynamics – methods: numerical
2011/10/20
It has recently been shown that the terrestrial planets and asteroid belt can be reproduced if the giant planets underwent an inward-then-outward migration (the "Grand Tack"; Walsh et al 2011). Inward...
Strong Electroweak Phase Transitions in the Standard Model with a Singlet
Strong Electroweak Phase Transitions Standard Model Singlet
2011/10/14
It is well known that the electroweak phase transition (EWPhT) in extensions of the Standard Model with one real scalar singlet can be first-order for realistic values of the Higgs mass. We revisit th...
Quest for a new form of matter inside compact stars compels us to examine the thermodynamical properties of the phase transitions. We closely consider the first-order phase transitions and the phase e...
Large-Scale Gas Dynamics in the Adhesion Model: Implications for the Two-Phase Massive Galaxy Formation Scenario
the Adhesion Model Implications the Two-Phase Massive Galaxy Formation Scenario
2011/1/13
The mass assembly and star formation histories of massive galaxies identified at low redshift z in different cosmological hydrodynamical simulations, have been studied through a detailed follow-up ba...
Curvature Perturbations and non-Gaussianities from Waterfall Phase Transition during Inflation
Curvature Perturbations non-Gaussianities
2011/1/13
We consider a variant of hybrid inflation where the waterfall phase transition happens during inflation. By adjusting the parameters associated with the mass of the waterfall field, we arrange that t...
Structure in phase space associated with spiral and bar density waves in an N-body galactic disk
bar density waves N-body galactic disk
2011/1/11
An N-body simulation of a Galactic disk is used to study the stellar phase space distribution or velocity distributions in different local neighborhoods. Pattern speeds identified in Fourier spectrogr...
Imprints of the QCD Phase Transition on the Spectrum of Gravitational Waves
the QCD Phase Transition the Spectrum
2011/1/10
We have investigated effects of the QCD phase transition on the relic GW spectrum applying several equations of state for the strongly interacting matter: Besides the bag model, which describes a firs...
Pasta Structures of Quark-Hadron Phase Transition in Proto-Neutron Stars
Pasta Structures Quark-Hadron Phase Transition
2011/1/11
We study the quark-hadron mixed phase in proto-neutron stars with the finite-size effects. In the calculations of pasta structures appeared in the mixed phase, the Gibbs conditions require the pressur...
On the Rebrightenings of Classical Novae during the Early Phase
Classical Novae the Early Phase
2011/1/11
We report on the spectral evolution of 6 classical novae, V1186 Sco, V2540 Oph, V4745 Sgr, V5113 Sgr, V458 Vul, and V378 Ser, based on the low-resolution spectra obtained at the Fujii-Bisei Observator...
Supersoft X-ray Phase of Single Degenerate Type Ia Supernova Progenitors in Early Type Galaxies
Supersoft X-ray Phase Single Degenerate Type
2011/1/13
In the single degenerate (SD) scenario for Type Ia supernova (SN Ia) progenitors, an accreting white dwarf (WD) is expected to undergo a supersoft X-ray source (SSS) phase. Recently, Gilfanov & Bogdan...
Warm dark matter at small scales: peculiar velocities and phase space density
Warm dark matter small scales peculiar velocities phase space density
2010/11/12
We study the scale and redshift dependence of the power spectra for density perturbations and
peculiar velocities, and the evolution of a coarse grained phase space density for (WDM) particles that d...
The pasta phase and its consequences on neutrino opacities
pasta phase neutrino opacities
2010/11/16
In this paper, we calculate the diffusion coefficients that are related to the neutrino opacities considering the formation of nuclear pasta and homogeneous matter at low densities. Our results show t...
A Model for Thermal Phase Variations of Circular and Eccentric Exoplanets

2010/11/9
We present a semi-analytic model atmosphere for close-in exoplanets that captures the essential
physics of phase curves: orbital and viewing geometry, advection, and re-radiation. We calibrate the mo...
The revival of an explosion mechanism of massive stars - the quark hadron phase transition during the early post bounce phase of core collapse supernovae
Core collapse supernovae protoneutron stars general relativity radiation hydrodynamics
2010/11/16
We explore explosions of massive stars, which are triggered via the quark hadron phase transition during the early post bounce phase of core collapse supernovae. The onset of quark matter is favored u...
Possible detection of phase changes from the non-transiting planet HD 46375b by CoRoT

2010/11/15
Context. The present work deals with the detection of phase changes in an exoplanetary system. HD 46375 is a solar analog known to host a non-transiting Saturn-mass exoplanet with a 3.0236 day period....
