Broadband X-ray observations of the periodic optical source ZTF J185139.81+171430.3 and its identification as a massive intermediate polar

Ren Deng, Kaya Mori, Eric Miao +5

We present X-ray observations of the periodic optical source ZTF J185139.81+171430.3 (hereafter ZTF J1851) by the XMM, NICER and NuSTAR telescopes. The source was initially specula…

Phase-resolved spectroscopic observations of the magnetic cataclysmic binary EF Eridani: Revealing complex magnetic accretion during a high state

Zwidofhela N. Khangale, Stephen B. Potter, David A. H. Buckley +1

We present high-resolution, phase-resolved spectroscopic observations of the polar EF Eri, obtained with SALT and the SAAO 1.9-m telescope during its recent emergence from a three-…

A Link Between White Dwarf Pulsars and Polars: Multiwavelength Observations of the 9.36-Minute Period Variable Gaia22ayj

Antonio C. Rodriguez, Kareem El-Badry, Pasi Hakala +30

White dwarfs (WDs) are the most abundant compact objects, and recent surveys have suggested that over a third of WDs in accreting binaries host a strong (B 1 MG) magnetic…

NuSTAR broadband X-ray observation of EF Eri following its reawakening into a high accretion state

Luke W. Filor, Kaya Mori, Gabriel Bridges +7

We present the first NuSTAR X-ray observation of EF Eri, a well-known polar system. The NuSTAR observation was conducted in conjunction with NICER, shortly after EF Eri entered a h…

A new way to find symbiotic stars: accretion disc detection with continuum survey photometry

A. B. Lucy, J. L. Sokoloski, G. J. M. Luna +10

Symbiotic stars are binaries in which a cool and evolved star of luminosity class I-III accretes onto a smaller companion. However, direct accretion signatures like disc flickering…

IGR J19552+0044: A new asynchronous short period polar: "Filling the gap between intermediate and ordinary polars"

G. Tovmassian, D. Gonzalez-Buitrago, J. Thorstensen +23

Based on XMM--Newton X-ray observations IGR J19552+0044 appears to be either a pre-polar or an asynchronous polar. We conducted follow-up optical observations to identify the sourc…
