Compact stellar systems in the Fornax cluster: a UV perspective
Steffen Mieske, Michael Hilker, Dominik J. Bomans +4
In recent years, increasing evidence for chemical complexity and multiple stellar populations in massive globular clusters (GCs) has emerged, including extreme horizontal branches…
Spitzer Observations of Bok Globule B335: Isolated Star Formation Efficiency and Cloud Structure
Amelia M. Stutz, Mark Rubin, Michael W. Werner +8
We present infrared and millimeter observations of Barnard 335, the prototypical isolated Bok globule with an embedded protostar. Using Spitzer data we measure the source luminosit…
Numerical Simulations of a Protostellar Outflow Colliding with a Dense Molecular Cloud
Chang Hyun Baek, Jongsoo Kim, Minho Choi
High-resolution SiO observations of the NGC 1333 IRAS 4A star-forming region showed a highly collimated outflow with a substantial deflection. The deflection was suggested to be ca…
Turbulence and Magnetic Fields in the Large Scale Structure of the Universe
Dongsu Ryu, Hyesung Kang, Jungyeon Cho +1
The nature and origin of turbulence and magnetic fields in the intergalactic space are important problems that are yet to be understood. We propose a scenario in which turbulent fl…
Millimeter Imaging of HH 24 MMS: A Misaligned Protobinary System
Miju Kang, Minho Choi, Paul T. P. Ho +1
The HH 24 MMS protostellar system was observed in the 6.9 mm continuum with a high angular resolution (0.5"). HH 24 MMS was resolved into two sources. The separation between source…
The Effects of Clumps in Explaining X-ray Emission Lines from Hot Stars
J. P. Cassinelli, R. Ignace, W. L. Waldron +3
It is now well established that stellar winds of hot stars are fragmentary and that the X-ray emission from stellar winds has a strong contribution from shocks in winds. Chandra hi…
