Binary System of Stellar Corpses Sheds Secrets
Mukremin Kilic (Universitiy of Oklahoma) and collaborators report the discovery of the first millisecond pulsar with a pulsating white dwarf companion. High-speed photometry obtained using the Gemini Multi-Object Spectrograph (GMOS) on Gemini North revealed optical variability attributable to the roughly 0.2MSun white dwarf. The system offers opportunities for future investigation of mass, internal structure, and physical characteristics of these stellar endpoints, which are connected directly to their evolutionary paths. The work is in press in Monthly Notices of the Royal Astronomical Society, and a preprint is available.

KASI Joins Gemini as a Limited-term Partner
The Korea Astronomy and Space Sciences Institute (KASI) will be a limited-term partner of Gemini in 2015. A memorandum of understanding is signed, providing the Korean community access to both telescopes. The total amount of time available is roughly 20 nights over the year. We look forward to working with our new partner!

Bring One, Get One: Support for Early Career Observing Experiences
The first early-career visitors in the “Bring One, Get One” program have observed at Gemini North, and Gemini South will receive its first visitors soon. All visiting observers are eligible to apply to help their students gain hands-on observing experience.
