Request for additional epsilon Aurigae observations
Active Dates: Oct. 29, 2009 – Nov. 5, 2009
Abstract:
Dr. Robert Stencel (Denver U.) requests enhanced coverage of the bright, long-period eclipsing binary star epsilon Aurigae through Wednesday. Observations are requested beginning immediately (October 29, 2009; JD 2455134) and continuing through November 5, 2009 (JD 2455141). This request is in conjunction with scheduled observations with the CHARA optical interferometer at Mount Wilson in California. Optical photometry by a number of observers will provide a continuous photometric baseline of epsilon Aurigae during the course of the interferometry, enabling Stencel and collaborators to more easily interpret the interferometric images.
Justification:
These interferometric observations are being made to image the system as it enters eclipse; the optical interferometric observations being made by CHARA are completely analogous to those made with radio interferometers like the Very Large Array, and allow ground based observers to obtain images with far higher resolution than a single optical telescope is capable of.
