Galaxy evolution in groups and clusters: star formation rates, red sequence fractions, and the persistent bimodality
methods: statistical-galaxies: groups: general-galaxies: clusters:general-galaxies: haloes-galaxies: evolution-galaxies: star formation
2011/10/17
Using galaxy group/cluster catalogs created from the Sloan Digital Sky Survey Data Release 7, we examine in detail the specific star formation rate (SSFR) distribution of satellite galaxies and its de...
Star-forming Region Sh 2-233IR I. Deep NIR Observations toward the Embedded Stellar Clusters
Star-forming Sh 2-233IR Observations Embedded Stellar Clusters
2011/10/9
We observed the Sh 2-233IR (S233IR) region with better sensitivity in near-infrared than previous studies for this region. By applying statistical subtraction of the back- ground stars, we identified ...
Investigations of mass segregation are of vital interest for the understanding of the formation and dynamical evolution of stellar systems on a wide range of spatial scales. Our method is based on the...

The numerous and massive young star clusters in blue compact galaxies (BCGs) are used to investigate the properties of their hosts. We test whether BCGs follow claimed relations between cluster popula...
Radiation-driven winds of hot luminous stars. XVI. Expanding atmospheres of massive and very massive stars and the evolution of dense stellar clusters
Radiation mechanisms: general – Methods: numerical – Radiative transfer – early Universe – Stars: early-type – mass- loss – stellar winds – very massive stars – stellar evolution
2011/9/27
Context: Starbursts, and particularly their high-mass stars, play an essential role in the evolution of galaxies. The winds of massive stars not only significantly influence their surroundings, but th...
