Engineering at the SOAR Telescope in Chile
I recently participated in an engineering trip to the SOAR Telescope in Chile, where I helped with numerous maintenance and upgrades for the Goodman Spectrograph.
Pulsations and Evolution
Kepler finds a new binary system with a Delta Scuti pulsator.
Orbital Decay of X-ray Binaries
In today’s paper, the authors study how the periods of two black hole x-ray binaries are changing. They find that the periods are decaying faster than expected based on standard theoretical arguments.
Progenitors of AM CVn systems
The progenitors of a special type of cataclysmic variable, AM CVn, and possibly supernovae have been found.
When Galaxies Interact
The authors seek to understand how two galaxies are interacting with each other.
