The stellar evolution of Luminous Red Galaxies, and its dependence on colour, redshift, luminosity and modelling
galaxies evolution - cosmology observations - surveys
2010/11/15
We present a series of colour evolution models for Luminous Red Galaxies (LRGs) in the 7th spectroscopic data release of the Sloan Digital Sky Survey (SDSS), computed using the full-spectrum fitting c...
Binary YORP and Evolution of Binary Asteroids
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/31
The rotation states of kilometer sized near earth asteroids are known to be affected by the YORP effect.
A Chandra Census of C2D YSOS: Evolution of X-ray Emission
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
We present an analytical study of a large sample of ~109 young stellar objects in the X-ray. Our objects were detected in X-ray independent of age. Unexpectedly, the X-ray energy is somewhat correlate...
Thermal evolution and interior models of the transiting super-Earth GJ 1214b
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/23
The planet GJ 1214b is the second known super-Earth with a measured mass and radius. Orbiting a quiet M-star, it receives considerably less mass-loss driving X-ray and UV radiation than CoRoT-7b, so t...
Proposed cosmological surveys will make use of photometric redshifts of galaxies that are significantly fainter than any complete spectroscopic redshift surveys that exist to train the photo-z methods...
