Monitoring of the Recurrent Nova U Scorpii

Active Dates: Jan. 22, 2008 – Jan. 22, 2010


Abstract:

Dr. Bradley E. Schaefer (Louisiana State University) requests increased monitoring of the recurrent nova U Scorpii (AAVSO 1616-17) over the next 24 months. Observers are asked to add U Sco to their regular observing program and to monitor the star in advance of an outburst predicted to occur around 2009.3 +/- 1.0 year.

Justification:

Schaefer predicts that because the nova outburst occurs after a certain amount of material collects on the white dwarf, and because the quiescent brightness of the star follows the mass accretion rate, we can predict when the accreted mass reaches the nova ignition point.
