Request to monitor three dwarf novae in support of radio observations
Active Dates: Nov. 13, 2008 – Nov. 13, 2009
Abstract:
Dr. Elmar Koerding (CEA Saclay & Universite Paris Diderot) and collaborators have requested our assistance to monitor the dwarf novae YZ Cnc, Z Cam, and EM Cyg for outbursts, in support of radio observations with the NRAO Very Large Array telescope. This new campaign is a continuation of the projects described in AAVSO Alert Notices 345 and 360. Koerding and collaborators are attempting to detect and characterize radio emission from dwarf novae during outbursts. Rapid optical detection of the onset of outbursts will be used to trigger target-of-opportunity (TOO) observations with the NRAO Very Large Array (VLA) in New Mexico. Observations of SS Cygni during the first campaign yielded important new results, and a paper on those observations was published in the journal Science (Koerding et al., 2008, Science 320, 1318).
Justification:
Rapid optical detection of the onset of outbursts will be used to trigger target-of-opportunity (TOO) observations with the NRAO Very Large Array (VLA) in New Mexico.
