Habitability of Super-Earth Planets around Main-Sequence Stars including Red Giant Branch Evolution: Models based on the Integrated System Approach
Main-Sequence Stars including Red Giant Branch Evolution Models based Integrated System Approach
2011/10/20
In a previous study published in Astrobiology, we focused on the evolution of habitability of a 10 M_E super-Earth planet orbiting a star akin to the Sun. This study was based on a concept of planetar...
Detailed Abundances of the Solar Twins 16 Cygni A and B: Constraining Planet Formation Models
Detailed Abundances Solar Twins Constraining Planet Formation Models
2011/10/10
Results of a detailed abundance analysis of the solar twins 16 Cyg A and 16 Cyg B based on high-resolution, high signal-to-noise ratio echelle spectroscopy are presented. 16 Cyg B is known to host a g...
Distance determination for RAVE stars using stellar models III: The nature of the RAVE survey and Milky Way chemistry
Stars: distances, Stars: fundamental parameters, Galaxy: abundances, Galaxy: disk, Galaxy: stellar content, Galaxy: structure
2011/9/29
We apply the method of Burnett & Binney (2010) for the determination of stellar distances and parameters to the internal catalogue of the Radial Velocity Experiment (Steinmetz et al. 2006). Subsamples...
Orbit-Based Dynamical Models of the Sombrero Galaxy (NGC 4594)
Dynamical Models Sombrero Galaxy (NGC 4594)
2011/9/29
We present axisymmetric, orbit-based models to study the central black hole, stellar mass-to-light ratio, and dark matter halo of NGC 4594 (M104, the Sombrero Galaxy). For stellar kinematics, we use p...
Probing bulk viscous matter-dominated models with Gamma-ray bursts
Probing viscous matter-dominated Gamma-ray bursts
2011/9/27
In this paper we extend the range of consistency of a constant bulk viscosity model to redshifts up to $z\sim 8.1$. In this model the dark sector of the cosmic substratum is a viscous fluid with press...

Statistical Synthesis Models。
In this paper we examine air densities derived from our realiza-
tion of aeronomic atmosphere models based on accelerometer measurements from
satellites in a low Earth's orbit (LEO). Using the adapt...
