Shortest-Period Polar Cataclysmic Variable Discovered
Gaia19bxc appears to contain a magnetic white dwarf and a metal-poor star in theory-defying close quarters — a configuration seen for the first time in a cataclysmic variable system.
Following Up on Flares: Can We Spot Black Hole Mergers in Active Galactic Nucleus Disks?
Astrobites reports on the possibility of merging black holes producing flares within the accretion disks surrounding active supermassive black holes.
A Strange Brown Dwarf Gets Stranger
A brown dwarf that made headlines for showing signs of auroral activity is back in JWST’s sights — and it’s now doubly interesting.
Investigation of the First Radio-Bright Off-Nuclear Tidal Disruption Event
The tidal disruption event AT 2024tvd happened outside the nucleus of its host galaxy, indicating the presence of a wandering or recoiling massive black hole. What can radio observations tell us about this unusual event?
