PI: Dr. Peter M. Garnavich University of Notre Dame Y CoI: Mr. Colin Littlefield University of Notre Dame N CoI: Dr. Mark Kennedy University College Cork N ------------------------------------------------------------------------------------ Abstract White dwarfs (WD) in intermediate polars (IPs) rotate rapidly and have sufficiently high magnetic-field strengths to channel gas from an accretion disk onto their magnetic poles. The WD in FO Aquarii, the so-called ``King of the IPs, '' began spinning down in 2015 after spinning up for the preceding quarter-century. Almost immediately, it began to drop into a series of low-accretion states in the optical and X-rays, behavior that was never observed when the WD was spinning up. The power generated by the spin-down is nearly 0.5 Solar luminosities, which raises a very basic question: where is this energy deposited? We hypothesize that during FO Aqr's low states, the WD powers an outflow that removes angular momentum from the WD, causing the observed spin-down. This scenario is similar to X-ray binaries in which a magnetized neutron star, after being spun-up by accretion, develops a centrifugal barrier that drives outflows or even a jet. FO Aqr's spin-down power is sufficiently high to drive a substantial outflow, and although optical spectra of FO Aqr during its recent low state hint at the existence of this feature, ultraviolet spectra are vastly more sensitive to outflowing gas because of the presence of C IV and Si IV resonance lines. We propose HST/COS observation of FO Aqr to test for outflow/jet signatures such as P-Cygni line profiles that were not present in UV spectra taken in 1995 when the WD was spinning up. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will observe the intermediate polar FO Aquarii with COS in time-tag mode. We will used the G140L grating centered on 1105 angstroms. The first visit will be 3 consecutive HST orbits that will cover 80% of the 4.85-h binary orbit. The gaps in phase coverage caused by Earth occultations will be filled by a second visit 30 orbits after visit 1. The brightness of FO Aqr has been near its all-time maximum of V=13.5 for decades. We have used FOS spectra taken in 1995 to estimate fluxes and count rates for the COS observations. We plan a NUV imaging acquisiton for both visits. The NUV flux based on XMM/OM and SWIFT/UVOT observations is 4e-14 erg/cm2/s/A, so we will use the BOA and MirrorA for the acqusitions. To get the S/N=30 image will take a 22sec exposure. The position and proper motion of FO Aqr is very well determined by Gaia EDR3. ------------------------------------------------------------------------------------ 16727( 10) - 04-Aug-2023 16:06:51 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 V-FO-AQR STAR, INTERMEDIATE RA=22H17M55.3797S +/- 0.00003", J2000 V = 14.0 +/- 1.0 POLAR DEC=-08D21'3.76" +/- 0.00002" Reference Frame: ICRS Extended: NO Comments: Coordinates and PM are from Gaia EDR3.
