Kuiper et al. (2006) Atel 684:
- Flux of ~2.3 mCrab in the 20-65 keV band, with potential counterparts: 1RXS J145341.1-552146 and
1RXS J145349.4-552144.

Mukai et al. (2006) Atel 686:
- X-ray spectrum requires at least two components to be fitted:
a hard power law (with photon index ~ 1.0) and a soft blackbody (kT~70 eV)
with little absorption,
- Spectrum is reminiscent of
certain magnetic cataclysmic variables.
- UVOT source at magnitude 17.59+/-0.02 in the UVW1 filter

Masetti et al. (2006) Atel 783:
- Balmer and HeI lines in emission at z = 0
- likely Cv
|
|
Barlow et al. (2006) :
- 20-100 keV Power law photon index 3.1, or bresstrahlung kT=11.1 keV
|
|
Masetti et al. (2006) :
- Halpha, Hbeta, HeII emission lines
- R=15.4
- d~190 kpc
|

Monard (2008):
- Improved period of
0.13153d +/- 0.0001d derived by considering sharp minima in the
(optical) lightcurves over a period of 29d.
|
|
Potter et al. 2009 (MNRAS):
- Optical observations
- Rapid photometry and polarimetry => orbital period 3.1564 hours
- Orbital circulary polarized modulation from 0 to -18% seen over 95% of the orbit=> single pole accretion
- Clearly identify source as a Polar
- QPO of period 5-6 minutes detected in the source optical
light curve on specific occasion
- Detection of these QPO in circular polarimetry
- Associate the QPO to the emission site
at the cyclotron emitting shock region
|
|
Butters et al. 2011 (A&A):
- No coherent modulation at period of 3.1 hr
- Presence of a clear signal at periods likely harmonically related period
- Spectra consistent with the source being a magnetic CV, presence of iron line
- Possible contamination
by a nearby hard X-ray object.
