PI: Dr. Krystian Ilkiewicz Warsaw University Observatory Y CoI: Dr. Noel Castro Segura University of Warwick Y CoI: Simone Scaringi Durham University N CoI: Prof. Christian Knigge University of Southampton N CoI: Dr. Luca Izzo INAF - Osservatorio Astronomico di N Capodimonte ------------------------------------------------------------------------------------ Abstract BZ Cam is one of only three cataclysmic variables with bow shocks known. Recent observation revealed that the morphology of the BZ Cam bow shock is more complicated than previously thought, posing a challenge to the models of formation and structure of bow shocks. While the BZ Cam bow shock was detected in the UV range, it was never observed with UV spectroscopy. Here we propose to obtain HST STIS spectroscopy of the bow shock, which could reveal the emission mechanism of UV radiation. This will reveal the nature of its complex morphology, and in turn enhance our understanding of bow shocks in general. Depending on what the observations will reveal, the HST spectrum could shed light on the energy/mass release processes in cataclysmic variables outflows, impacting our models of binary evolution and accretion physics. Alternatively, it may provide insights into the impact of cataclysmic variables on the nearby interstellar medium, influencing our understanding of galactic chemistry and the broader context of galaxy evolution. ------------------------------------------------------------------------------------ Observations Description ------------------------ We aim to obtain a simultaneous spectrum of the bowshock from BZ Cam, we changed the PA to go trhough the region of highest optical emission. PA = 200- 240. To avoid getting too close to the bright star and facilitate shceduling we select 232-242 PA range To improve the quality of the spectrum we set a dither pattern leaving the star at 0.8 and 1.8 arsec from the edge of the slit, then -0.2 and -1.2 arsec outside of the slit (hence the - symbol). This will map 4 arminits extending the spatial coverage and minimising the impact of the shadow caused by the shadow of the gird wire. A NUV exposure was added to one orbit in the second visit G240L to cover the full near to far-UV spectrum. The buffer dumps for the brigth star are double of the selected buffer dumps, this is to avoid losing data due to exceeding the buffer size. ------------------------------------------------------------------------------------ 17750( 6) - 04-Jun-2025 12:44:55 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 2 EGB-4 STAR, ACCRETION DISK, RA=06H29M33.9600S, J2000 V = 13.27 NOVA-LIKE DEC=+71D04'36.39" Reference Frame: ICRS Comments: This object was generated by the targetselector and retrieved from the SIMBAD database.
