The team conducted an in-depth analysis of ZTF J0112+5827, including X-ray and time-domain spectroscopic observations. The findings confirmed that the system belongs to the polar subclass of cataclysmic variables, where a white dwarf and a companion star interact without forming an accretion disk. Instead, emissions are generated from the accretion stream and magnetic field lines.<\/p>\n<p>As <a href=\"https:\/\/phys.org\/news\/2025-03-astronomers-polar-cataclysmic-variable.html\" target=\"_blank\" rel=\"nofollow noopener\">reported<\/a>, light curve analysis revealed double-spiked variations, attributed to cyclotron radiation from charged particles on the white dwarf&#8217;s surface. The system&#8217;s strong magnetic field, measured at approximately 38.7 MG, reinforced its classification as a polar. Researchers estimated the white dwarf&#8217;s mass at around 0.8 times that of the Sun, while the donor star&#8217;s mass was calculated to be roughly 0.07 solar masses. The system has been placed at a distance of approximately 1,186 light-years.<\/p>\n<h2 id=\"potential-gravitational-wave-source\">Potential Gravitational Wave Source<\/h2>\n<p>As per the research, ZTF J0112+5827 may emit gravitational waves detectable by the <a href=\"https:\/\/www.gadgets360.com\/tags\/lisa\">Laser Interferometer Space Antenna<\/a> (LISA), a mission set for launch in 2035. The paper&#8217;s authors noted that future studies on the system&#8217;s component masses would be essential in determining its viability as a gravitational wave source.<\/p>\n<\/div>\n<p><br \/>\n<br \/><a href=\"https:\/\/www.gadgets360.com\/science\/news\/astronomers-discover-new-polar-cataclysmic-variable-ztf-j0112-5827-7861334#rss-gadgets-news\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A new cataclysmic variable system of the polar subclass has been identified by astronomers using the ROentgen SATellite (ROSAT).
