Astronomers know that while large stars can end their lives as violently cataclysmic supernovae, smaller stars end up as planetary nebulae--colorful, glowing clouds of dust and gas. In recent decades,...
The Progenitor Mass of SN 2011dh from Stellar Populations Analysis
Progenitor Mass Stellar Populations Analysis
2011/10/18
Using Hubble Space Telescope (HST) photometry, we characterize the age of the stellar association in the vicinity of supernova (SN) 2011dh and use it to infer the zero-age main sequence mass (M_{ZAMS}...
Dynamical Tides in Eccentric Binaries and Tidally-Excited Stellar Pulsations in KEPLER KOI-54
binaries: close|stars: oscillations|stars: rotation|stars: individual: HD187091 (KOI-54)
2011/10/13
Recent observation of the tidally-excited stellar oscillations in the main-sequence binary KOI-54 by the KEPLER satellite provides a unique opportunity for studying dynamical tides in eccentric binary...
SPIDER - V. Measuring Systematic Effects in Early-Type Galaxy Stellar Masses from Photometric SED Fitting
Measuring Systematic Effects Early-Type Galaxy Stellar Masses Photometric
2011/10/17
We present robust statistical estimates of the accuracy of early-type galaxy stellar masses derived from spectral energy distribution (SED) fitting as functions of various empirical and theoretical as...

This contribution to the Stellar Clusters & Associations: A RIA Workshop on Gaia deals with surveys of stars, in particular spectroscopic surveys, with attention to their impact on cluster studies, an...
Outflow activities in the young high-mass stellar object G23.44-0.18
stars: pre-main sequence—ISM:molecules—ISM: individual (G23.44-0.18)—stars: formation
2011/9/29
We present an observational study towards the young high-mass star forming region G23.44-0.18 using the Submillimeter Array. Two massive, radio-quiet dusty cores MM1 and MM2 are observed in 1.3 mm con...
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...
