13400( 15) - 18-Sep-2013 17:40:19 - [ 1] HUBBLE SPACE TELESCOPE OBSERVING PROGRAM 13400 Version: 15 Check-in Time: 18-Sep-2013 17:40:19 STScI Edit Number: 5 Title The Surprising Ejecta Geometry of Recurrent Nova T Pyx ------------------------------------------------------------------------------------ Type Cycle GO 21 ------------------------------------------------------------------------------------ Investigators Contact? PI: Dr. Arlin Crotts Columbia University in the City of New Y York CoI: Dr. Jennifer Sokoloski Columbia University in the City of New N York CoI: Dr. Stephen S. Lawrence Hofstra University N ------------------------------------------------------------------------------------ Abstract Given the striking appearance of the old remnant that surrounds T Pyxidis (T Pyx), and the rapid pace at which this binary is currently evolving, T Pyx is one of the most stunning and interesting recurrent novae (RNe). But it is also one of the most disobedient, with the rate of mass transfer, the mass of the white dwarf, and the speed of the eruptions all inconsistent with standard expectations. In 2011, T Pyx experienced its first eruption in 45 years, providing observers with the long-awaited opportunity to determine the detailed properties of a T Pyx explosion and to test ideas about how these events might have led to T Pyx's unusual state. Our Cycle 20 HST observations of the light echo from the old remnant and direct line emission from the young remnant from 2011 provided one of several surprises: much of the old and young ejecta form a disk or ring inclined with respect to the plane of the sky. The 2011 ejecta also contain multiple kinematic components. But our Cycle 20 observations did not cover enough position angles, or span a long enough time baseline, to enable us to fully disentangle the spatial and velocity structure of the young remnant. In Cycle 21, we propose to take advantage of the unique moment in time when the young remnant is both large enough and bright enough for the spatial extent, expansion, and velocity structure to be clearly mapped. This research has implications for our understanding of the mass expelled in the 2011 eruption of T Pyx, the shaping of nova remnants, and the potential influence of nova eruptions on binary stellar evolution and the production of type Ia supernovae. ------------------------------------------------------------------------------------ Observations Description ------------------------ The purpose of the current version of this Phase II proposal is to execute the three-orbit Visit 1 as soon as possible but before June 28, 2013 if at all possible according to the APT in order to be consistent with the following. We are taking images and spectra of the recurrent nova T Pyx, a highly variable and unpredictable target. These consist of two sets of images (Visits 1 and 4); the first one (Visit 1) which must be taken as soon as possible, since the [Ne V] (F343N) emission nebula is fading rapidly. The second and third visits (Visits 2 and 3) are timed to occur when the STIS slit corresponds to the principal axes of the nebula so as to allow us to define the velocity field, hence must be executed in July and October 2013. Depending on the outcome of each Visit, we might be forced to change exposure times on subsequent Visits, 13400( 15) - 18-Sep-2013 17:40:19 - [ 2] for which a new APT file will be submitted if necessary. The specific timings and adaptive nature of our observations are spelled out in our Phase I proposal, which specify non-disruptive TOO observations.

It would be highly preferable if Visit 1 could be scheduled sufficiently in advance of Visit 2 in case exposure times need to be adjusted for Visit 2. This strategy was described in our Phase i proposal in connection with our non-disruptive TOO request. The goal of this Visit 1 is to acquire two dithered images of the T Pyx nebula, on in [Ne V] (F343N) requiring two orbits, and [O III] (F502N) requiring one orbit.

The purpose of Visit 7 is to supplement information obtained on the longer Visit 1 and spectroscopic Visit 5 to aid in their interpretation. It requires one orbit, mainly on [He II] (F459N) plus to a lesser extent on [Ne V] (F343N) and on [O III] (F502N).
