WISE J072003.20-084651.2: An Old and Active M9.5 + T5 Spectral Binary 6 pc from the Sun
Adam J. Burgasser, Michael Gillon, Carl Melis +8
[Abridged] We report observations of the recently discovered, nearby late-M dwarf WISE J072003.20-084651.2. Astrometric measurements obtained with TRAPPIST improve the distance mea…
Orbital, Superhump, and Superorbital Periods in the Cataclysmic Variables AQ Mensae and IM Eridani
E. Armstrong, J. Patterson, E. Michelsen +6
We report photometric detections of orbital and superorbital signals, and negative orbital sidebands, in the light curves of the nova-like cataclysmic variables AQ Mensae and IM Er…
Relativity, GPS, and the Validity of Common View Synchronization
Eric L. Michelsen
We show here that Common View Synchronization is valid to synchronize distant clocks. We describe the relativistic physics, noting that a prerequisite for synchronization is the ex…
Laser Ranging to the Lost Lunokhod~1 Reflector
T. W. Murphy, E. G. Adelberger, J. B. R. Battat +6
In 1970, the Soviet Lunokhod 1 rover delivered a French-built laser reflector to the Moon. Although a few range measurements were made within three months of its landing, these mea…
Long-term degradation of optical devices on the moon
T. W. Murphy, E. G. Adelberger, J. B. R. Battat +6
Forty years ago, Apollo astronauts placed the first of several retroreflector arrays on the lunar surface. Their continued usefulness for laser-ranging might suggest that the lunar…
APOLLO: the Apache Point Observatory Lunar Laser-ranging Operation: Instrument Description and First Detections
T. W. Murphy, E. G. Adelberger, J. B. R. Battat +10
A next-generation lunar laser ranging apparatus using the 3.5 m telescope at the Apache Point Observatory in southern New Mexico has begun science operation. APOLLO (the Apache Poi…
