The Factory and The Beehive I. Rotation Periods For Low-Mass Stars in Praesepe
Factory Beehiv Rotation Periods Low-Mass Stars Praesepe
2011/10/12
Stellar rotation periods measured from single-age populations are critical for investigating how stellar angular momentum content evolves over time, how that evolution depends on mass, and how rotatio...
The host galaxies and black-hole:galaxy mass ratios of luminous quasars at z~4
galaxies: active – galaxies: fundamental parameters – galaxies: high-redshift –galaxies: photometry – infrared: galaxies – quasars: general
2011/10/8
We present and analyse the deepest, high-quality Ks-band images ever obtained of luminous quasars at z~4, in an attempt to determine the basic properties of their host galaxies less than 1 Gyr after t...
Winds from Low Mass Stars：impact on the ISM。
The Mass/Eccentricity Limit in Double Star Astronomy
Stellar evolution statistics binaries
2009/5/19
A research that we conducted in 1963 on the evolution of
the binaries based on the available orbital data to obtain a philosophical
degree, led to the establishment of an interesting and new diagram...
GRADIENT OF MEAN MASS OF A STAR IN THE FIELD OF GLOBULAR CLUSTERS
globular clusters general-Stars fundamental parameters (masses)
2009/2/16
Based on the relevant available data, the distributions of masses
and apparent magnitudes of stars belonging to globular star clusters are simulated.
The simulations are aimed at examining the in°ue...
