The evolution of globular clusters: Analysis of external effects and determination of progenitor populations
Globular cluster evolution Evolution The Milky Way. Base elliptical galaxies galaxy
2014/12/9
We include external effects in the Fokker-Planck scheme for studying globular cluster evolution. We use this method to study cluster evolution under the combined influence of relaxation, tidal heating...
Pasadena, CA—Wolf-Rayet stars are very large and very hot. Astronomers have long wondered whether Wolf-Rayet stars are the progenitors of certain types of supernovae. New work from the Palomar Transie...
The Progenitor Mass of SN 2011dh from Stellar Populations Analysis
Progenitor Mass Stellar Populations Analysis
2011/10/13
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}...
Another Look at the EBS: A Stellar Debris Stream and a Possible Progenitor
Another Look Stellar Debris Stream Possible Progenitor
2011/7/25
Using the Sloan Digital Sky Survey Data Release 7, we reexamine the Eastern Banded Structure (EBS), a stellar debris stream first discovered in Data Release 5 and more recently detected in velocity sp...
Panchromatic Observations of SN 2011dh Point to a Compact Progenitor Star
Panchromatic Observations Compact Progenitor Star
2011/7/10
We report the discovery and detailed monitoring of X-ray emission associated with the Type IIb SN 2011dh using data from the Swift and Chandra satellites, placing it among the best studied X-ray super...
Caltech Core-Collapse Project (CCCP) observations of type IIn supernovae: typical properties and implications for their progenitor stars
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Solar and Stellar Astrophysics (astro-ph.SR)
2010/10/13
Type IIn Supernovae (SNe IIn) are rare events, constituting only a few percent of all core-collapse SNe, and the current sample of well observed SNe IIn is small. Here, we study the four SNe IIn obser...
