A Multi-wavelength Study of Swift J0503.7-2819: a Chimeric magnetic CV
We present multi-wavelength temporal and spectral characteristics of a magnetic cataclysmic variable (MCV) Swift J0503.7-2819, using far ultraviolet (FUV) and X-ray data from AstroSat, supplemented with optical data from the Southern African Large Telescope and X-ray data from the XMM-Newton and Swi...

magnetic cataclysmic variable (MCV) Swift J0503.7-2819, using far ultraviolet
(FUV) and X-ray data from AstroSat, supplemented with optical data from the
Southern African Large Telescope and X-ray data from the XMM-Newton and Swift
observatories. The X-ray modulations at 4897.6657 s and 3932.0355 s are
interpreted as the orbital ($P_{\Omega}$) and spin ($P_{\omega}$) period,
respectively, and are consistent with prior reports. With a spin-orbit period
ratio of 0.8 and $P_{\Omega}$ falling below the period gap (2-3 hrs) of CVs,
Swift J0503.7-2819 would be the newest addition to the growing population of
nearly synchronous MCVs, which we call EX Hya-like systems. Hard X-ray

luminosity of $<$ $2.5\times10^{32} erg s^{-1}$, as measured with the Swift
Burst Alert Telescope, identifies it to be a low-luminosity intermediate polar,
similar to other EX Hya-like systems. The phenomenology of the light curves and
the spectral characteristics rule out a purely disc-fed/stream-fed model and
instead reveal the presence of complex accretion structures around the white
dwarf. We propose a ring-like accretion flow, akin to EX Hya, using period
ratio, stability arguments, and observational features. An attempt is made to
differentiate between the asynchronous polar/nearly-synchronous intermediate
polar nature of Swift J0503.7-2819. Further, we note that with the advent of
sensitive surveys, a growing population of MCVs that exhibit characteristics of
both polars and intermediate polars is beginning to be identified, likely
forming a genealogical link between the two conventional classes of MCVs.</description><identifier>DOI: 10.48550/arxiv.2310.07293</identifier><language>eng</language><subject>Physics - High Energy Astrophysical Phenomena ; Physics - Solar and Stellar Astrophysics</subject><creationdate>2023-10</creationdate><rights>http://arxiv.org/licenses/nonexclusive-distrib/1.0</rights><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>228,230,780,885</link.rule.ids><linktorsrc>$$Uhttps://arxiv.org/abs/2310.07293$$EView_record_in_Cornell_University$$FView_record_in_$$GCornell_University$$Hfree_for_read</linktorsrc><backlink>$$Uhttps://doi.org/10.48550/arXiv.2310.07293$$DView paper in arXiv$$Hfree_for_read</backlink></links><search><creatorcontrib>Pradeep, Kala G</creatorcontrib><creatorcontrib>Singh, Kulinder Pal</creatorcontrib><creatorcontrib>Dewangan, G.
