About this award
The National Aeronautics and Space Administration (NASA) awarded a $61,332.44 grant to The Trustees of Columbia University in the City of New York to conduct research on changes in the accretion disk boundary layer of a symbiotic recurrent nova, T CRB. The research aims to observe T CRB when it returns to its quiescent state, which may occur during NASA's 19th Announcement of Opportunity (AO19), in order to test the hypothesis that nova eruptions in T CRB are preceded by periods of enhanced accretion onto the white dwarf due to accretion disk instability. This research will help improve the understanding of disk instability events in large accretion disks. The contract does not have a set-aside designation and is set to be completed by March 7, 2023.
Description
Changes in the amount of material reaching the accretion disk boundary layer can drastically modify its structure. We are witnessing such changes in a symbiotic recurrent nova, t CRB, for the first time. Two observations with nustar and XMM have revealed that the accretion rate has increased by a factor of about 10 and that the boundary layer has become optically thick. The next step toward our understanding of the current state is to observe t CRB when IT returns to its quiescence level, which may happen during AO19. This too observation will allow US to test the idea that nova eruptions in t CRB follow after multiyear periods of enhanced accretion onto the white dwarf due to an accretion disk instability. IT will also help US study disk instability events in large accretion disks.
