When it comes to directly imaging Earth-like exoplanets orbiting faraway stars, seeing isn’t always believing.
The ATLAS3D Project-- VIII: Modelling the Formation and Evolution of Fast and Slow Rotator Early-Type Galaxies within $Λ$CDM
galaxies elliptical and lenticular cD – galaxies formation – galaxies evolution – galaxies structure
2011/10/21
We propose a simple model for the origin of fast and slow rotator early-type galaxies (ETG) within the hierarchical $\Lambda$CDM scenario, that is based on the assumption that the mass fraction of ste...
On the linear coupling between fast and slow MHD waves due to line-tying effects
Magnetohydrodynamics Waves Magnetic fields Sun atmosphere—Sun oscillations
2010/11/10
Context. Oscillations in coronal loops are usually interpreted in terms of uncoupled magnetohydrodynamic (MHD) waves. Examples of these waves are standing transverse motions, interpreted as the kink M...
Standing Slow-Mode Waves in Hot Coronal Loops: Observations, Modeling, and Coronal Seismology
Solar activity Solar corona Coronal Seismology Coronal loops
2010/11/15
Strongly damped Doppler shift oscillations are observed frequently associated with flarelike events in hot coronal loops. In this paper, a review of the observed properties and the theoretical modelin...
Damping of Slow Magnetoacoustic Waves in an Inhomogeneous Coronal Plasma
Sun corona—active region—coronal loops—TRACE—MHD waves—heating
2010/9/16
We study the propagation and dissipation of slow magnetoacoustic waves in an inhomogeneous viscous coronal loop plasma permeated by uniform magnetic field. Only viscosity and thermal conductivity are ...

Slow-roll inflation Gauss-Bonnet correction
2010/3/19
We consider slow-roll inflation for a single scalar field with an arbitrary potential and an arbitrary non-minimal coupling to the Gauss-Bonnet term. By introducing a combined hierarchy of Hubble and ...
