TL;DR: In this paper, the authors studied the quantum gravitational effects in spherically symmetric black hole spacetimes and constructed the effective quantum spacetime felt by a pointlike test mass by ''renormalization group improving'' the Schwarzschild metric.

TL;DR: In this article, a grid-based analysis was used to estimate the fundamental properties of more than 500 main-sequence and sub-giant stars using the NASA Kepler data obtained during the first 10 months of Kepler science operations, when these solar-type targets were observed for one month each in survey mode.

TL;DR: It is found that the distribution of observed masses of these stars shows intriguing differences to predictions from models of synthetic stellar populations in the Galaxy.

TL;DR: In this paper, the authors analyzed solar-like oscillations in ~1700 stars observed by the Kepler Mission, spanning from the main sequence to the red clump, and found that the difference of the Δν-νmax relation for unevolved and evolved stars can be explained by different distributions in effective temperature and stellar mass, in agreement with what is expected from scaling relations.

TL;DR: In this paper, the fundamental properties of more than 500 main-sequence and sub-giant stars were estimated using the NASA Kepler mission data using two global asteroseismic parameters and complementary photometric and spectroscopic data.
