PI: Dr. Koji Mukai NASA Goddard Space Flight Center Y CoI: Dr. Gerardo Juan Manuel Luna Instituto de Ciencias Astronomica, de la N Tierra y del Espaci CoI: Dr. Jennifer L Sokoloski Columbia University in the City of New N York CoI: Dr. N.P.M Paul Kuin Mullard Space Science Laboratory Y CoI: Dr. Alejandro Pujol Universidad de Buenos Aires N ------------------------------------------------------------------------------------ Abstract Since 2014, the symbiotic recurrent nova T Coronae Borealis has been in a high accretion rate state, rapidly accumulating the hydrogen-rich fuel that the massive white dwarf in this system will need for its next nova eruption, expected within several years. T CrB is evolving within this high state, with the optical light showing a gradual fading. XMM observations in 2017, 2018, and 2020, however, suggested that the accretion rate remained relatively constant. The observed differences appear to be caused by changes in the intrinsic absorber, probably related to the accretion disk wind. We therefore propose a set of two joint XMM -HST observations to monitor the accretion rate through the Keplerian disk and the boundary layer, and the amount of X-ray/UV absorber during this crucial period. ------------------------------------------------------------------------------------ Observations Description ------------------------ This proposal aims to obtain ultraviolet spectroscopy during two epochs of XMM observations. We have been given 100ks XMM time which will be split between an observation around August 2021 and February 2022. The target, T CrB is a nearby recurrent nova which had eruptions in 1866 and 1946, 80 years apart, and is expected to have another eruption around the 2024. Recurrent novae have been sshown to have nearly identical lightcurves around their eruptions. This is especially important when planning HST observations, since we can follow brightnesss changes and compare them to the historical light curve - that from the 1936-1950 period. T CrB presented in the years prior to the nova eruption of 1946 a slow change in brightness above some shorter period variability which was within a magnitude of the overall light curve evolution. Initially it showed a brightening lasting a few years, then a dip in brightness lasting about a year, followed by the eruption of the 1946 nova. The current observations have shown an increase in brightness which can be matched to that in the years prior to the 1946 eruption. So far, a dimming has not been seen, suggesting the eruption is still more than a year in the future. However, our plan extends to February next year at which time the dimming may 16486( 28) - 17-Aug-2022 14:40:26 - [ 2] have commenced. Our original planning assumed the brightness seen with IUE in the 1978-1997 period, and thus our planning was off. At its current brightnesss, COS FUV cannot be used, and we have adopted our plan to use STIS for two orbits in the August 2021 timeframe, and also two STIS orbits in the February 2022 timeframe. Should the brightness drop to 0.35 times the current brightness, when COS can be used safely for the FUV, we will request the TTRB for changing configuration of the FUV to COS which at that time will give better S/N, but maintain STIS for NUV spectroscopy.. Important Notes: *** based on the historic light curve of this nova, the current brightening by ~2.5 mag can be expected to be followed some time in the next two years by a brightness dip. We have provided two plans: for the current brightness, spectroscopy with STIS only, while (if it happens during this project) after a sufficient loss of brightness occurs, we will switch to COS for FUV, STIS for NUV spectroscopy. *** We have split our 4 orbits to two orbits each, for the two epochs of coordinated XMM observations. *** the first epoch of XMM observation would likely be in the mid July 2021 to the beginning of October period during HST Cycle 28; the second epoch would likely be in the Mid January 2022 to the beginning of March that year during HST cycle 29. *** We will maintain monitoring of T CrB with the Swift XRT and UVOT instruments, and will request daily cadence prior to the planned HST observations. In addition we plan to have a ground-based observation campaign. This should provide the necessary information for a go/no go and for which planned setup to use. *** HST contact is Co-PI Paul Kuin *** reduced gyro : we should be able to handle an acq each orbit without problem. Jitter may affect the flux inside the slit, but the line ratios will still be of use. ------------------------------------------------------------------------------------ 16486( 28) - 17-Aug-2022 14:40:26 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 V-T-CRB STAR, RECURRENT NOVA RA=15H59M30.1571S +/- 0.003", J2000 V = 10. +/- 1.
